An essential guide to help you be better informed when purchasing borosilicate glassware. It covers material grade, product form, standards, volumetric accuracy, heating and cooling, closures, chemical compatibility, cleaning, inspection and lifecycle considerations. To view the PDF version of this guide, click the guide cover image.
Borosilicate glassware is widely used in school laboratories, research environments, clinical settings and industrial quality control. Although products can look very similar, performance can vary with glass composition, wall design, annealing quality, joint precision, vessel geometry, manufacturing control, physical condition and conformity to the applicable standards.
The most important starting point is the intended task. A borosilicate label on its own does not mean that an item is suitable for direct flame, a hotplate, pressure, vacuum, autoclaving or quantitative volume measurement. Always check the exact product datasheet, the applicable standard and your local risk assessment.
If you are short on time, match the intended application to the specification that matters most. The table below follows the updated buying priorities in the PDF guide.
| User / Application | Recommended Glassware | What to Prioritise |
|---|---|---|
| KS3 Science | General-purpose laboratory glassware selected for the exact practical | Clear markings, easy handling, economical pack sizes and, where rough handling is likely, reinforced-rim or documented heavy-duty products. |
| GCSE Chemistry and Biology | Appropriate borosilicate laboratory glassware for the specified method | Correct vessel form, product-specific heating or sterilisation approval where needed, clear markings and compatibility with the practical method. |
| A Level Practical Work | Task-specific borosilicate and calibrated volumetric products | Stated tolerances, standards, joint compatibility and any required heating, vacuum or pressure rating. |
| Accurate Solution Preparation | Calibrated volumetric flasks, pipettes and burettes | A stated tolerance, accuracy class and standard. Choose Class A or equivalent where the method or required uncertainty demands the tighter permissible error. |
| Heating Liquids | A vessel expressly designed for the intended heating method | Product-specific approval for flame, hotplate, mantle, bath or oven use, plus suitable support and thermal-shock guidance. |
| Storage of Reagents | Laboratory bottles with a compatible complete closure system | Glass, cap body, liner or gasket, pouring ring, chemical compatibility, usable headspace and storage conditions. |
| Light-Sensitive Materials | Amber or low-actinic laboratory bottles where specified | Verify the product’s stated wavelength protection rather than relying on colour alone. |
| Sterilisation and Media Prep | Glassware and closures expressly suitable for the selected sterilisation cycle | Documented autoclave compatibility, suitable headspace and the manufacturer’s venting, slow-exhaust and cooling instructions. |
| Specialist Assemblies | Rated glassware with compatible joints, adapters and supports | Complete joint designations and, for vacuum or pressure work, a specific rating for the intended differential. |
Choose the vessel form according to what the glassware must actually do. Capacity, accuracy, closure system, joint type and heating method should then be checked against the exact product specification.
| What Do You Need To Do? | Best Glassware Type | Specification to Check | Important Limitation |
|---|---|---|---|
| Mix, pour or carry out routine heating | Beaker | Griffin/low form or Berzelius/tall form, clean-pouring spout, suitable rim and product-specific heating approval where required | Beaker graduations are normally approximate and are not for quantitative volumetric measurement. |
| Swirl liquids during reactions or titrations | Conical / Erlenmeyer flask | Narrow neck, appropriate capacity and product-specific heating approval where required | Standard conical flasks should not normally be evacuated unless specifically designed and rated for vacuum. |
| Measure liquid volume | Measuring cylinder | Stated standard, tolerance and accuracy class where applicable; In/TC calibration marking | Do not use a measuring cylinder for direct heating. |
| Prepare a defined final volume | One-mark volumetric flask | Calibration, tolerance, class, reference temperature and In/TC marking | Do not use volumetric flasks for direct heating. |
| Deliver accurate liquid volumes | Pipette or burette | Relevant product standard, tolerance, class and Ex/TD calibration marking | Accuracy depends on the specific product calibration and correct use, not on borosilicate material alone. |
| Store liquids or media | Laboratory bottle | Thread size, cap body, liner or gasket, pouring ring, chemical compatibility and sterilisation rating | Ordinary reagent/media bottles are generally not for direct flame, hotplates, pressure or vacuum unless specifically rated. |
| Heat or react small samples | Test tube or boiling tube | Exact material and product suitability for the intended heating method, plus suitable holder or rack | Do not heat damaged or unknown-specification glassware. |
| Run reflux, distillation or controlled heating | Round-bottom flask and compatible jointed apparatus | Correct joint designation, compatible adapters, secure support and a suitable mantle or bath | Clips secure compatible joints but do not create a pressure rating. |
This guide is intended for people purchasing reusable laboratory glassware for education, research, clinical work, quality control and other laboratory environments.

Use the links below to jump directly to the section most relevant to your borosilicate glassware buying decision.
Borosilicate glass is a family of silica-based glasses containing significant amounts of boron trioxide. Borosilicate 3.3 is a widely used low-expansion laboratory grade whose low thermal expansion gives it greater resistance to thermal shock than soda-lime glass, although rapid or uneven temperature changes can still cause breakage.
A typical borosilicate 3.3 composition is approximately 80.6% SiO2, 13.0% B2O3, 4.0% Na2O and 2.3% Al2O3 by mass. Its mean linear expansion coefficient is approximately 3.3 × 10−6 K−1 between 20 °C and 300 °C.
The updated PDF places greater emphasis on the complete finished-product specification. These are the features worth comparing before purchase.
Where borosilicate 3.3 is required, look for the documented grade or relevant material standard rather than identifying the glass by appearance alone.
Uniform construction and appropriate annealing help limit local stress concentrations and residual manufacturing stress. Wall thickness alone is not a reliable measure of durability.
Beaded or reinforced rims may improve resistance to handling damage, while bases should be stable where the vessel is designed to stand upright.
Check that lines and numbers are crisp, evenly spaced and durable enough for the intended chemicals, cleaning agents and sterilisation cycles.
For quantitative work, check the stated tolerance, Class A/AS/B where applicable, calibration mode, reference temperature and relevant product standard.
The complete joint designation matters. A 24/29 joint and a 24/40 joint are not the same specification, even though they share the same nominal diameter.
Assess the cap body, liner or gasket, pouring ring, septum and any other closure components as one system against the exact chemical and temperature conditions.
Do not infer direct-heating, autoclave, vacuum or pressure suitability from the word borosilicate. Check the manufacturer’s stated limits for the exact item.
Different forms are designed for different jobs. The updated guidance distinguishes general-purpose vessels from calibrated volumetric ware, storage products and specialist jointed apparatus.
| Glassware Type | Best For | Key Features to Check | Buying Note |
|---|---|---|---|
| Beakers | General mixing, pouring and suitable heating applications | Low or tall form, beaded rim where required, clean-pouring spout and product-specific heating suitability | Graduations are normally approximate. |
| Conical Flasks | Swirling, reactions and titrations | Narrow neck, appropriate capacity and any required heating specification | Standard conical flasks should not normally be used under vacuum unless specifically designed and rated. |
| Measuring Cylinders | Calibrated or routine volume measurement, depending on the product | Tolerance, class where applicable, standard, stable base and readable scale | Use only where the cylinder’s specified tolerance is adequate for the method; do not use for direct heating. |
| Volumetric Flasks | Preparing solutions to a defined final volume | One-mark calibration, Class A or B as required, tolerance, standard and reference temperature | Do not use volumetric flasks for direct heating. |
| Burettes and Pipettes | Accurate delivery of measured liquid volumes | Relevant standard, maximum permissible error, accuracy class and Ex/TD calibration mode | Class marking does not by itself mean an individual calibration certificate is supplied. |
| Laboratory Bottles | Storage, media preparation and reagent handling | Thread size, cap body, liner or gasket, pouring ring, chemical compatibility and sterilisation instructions | Ordinary media and reagent bottles are generally not for direct flame, hotplates, pressure or vacuum unless specifically rated. |
| Test Tubes and Boiling Tubes | Small-scale reactions and heating where the exact product is suitable | Material specification, product condition and compatible racks or holders | Do not heat chipped, cracked, deeply scratched or etched glassware. |
| Round-Bottom Flasks | Even heating in suitable mantles or baths, reflux and distillation | Correct capacity, joint designation and secure support | Use an appropriate support; do not rest round-bottom forms unsupported on a flat surface. |
| Condensers and Adapters | Distillation, reflux and specialist assemblies | Complete joint designation, matching components and suitable clips or clamps | Joint clips secure compatible parts but do not create a pressure rating. |
Use this visual comparison as a starting point, then verify the material and finished-product specification of the exact item. Direct-heating, quantitative measurement and storage suitability are product- and method-dependent.
Compare common laboratory glassware forms, remembering that the exact material and product specification determine whether an item is suitable for direct heating, quantitative measurement or long-term storage.
For school laboratories, prioritise products that match the intended curriculum task and are easy to handle, inspect, clean and replace. Where rough handling is likely, reinforced-rim or documented heavy-duty products may be worth considering, but material grade or wall thickness should never be used as a substitute for the finished-product specification.
Look for clear markings, easy handling, suitable pack sizes and consistent product specifications.
Use only the correct vessel form and an item expressly suitable for the proposed flame, hotplate, mantle, bath or oven method.
Use calibrated volumetric products with a stated tolerance, class, standard and calibration mode where the method requires quantitative volume measurement.
Check bottle and closure compatibility, usable headspace and documented sterilisation or autoclave suitability where required.
Standardise sensible sizes and fittings where useful, but verify every product’s instructions for heating, cleaning, sterilising and inspection.
Inspect before use and remove chipped, cracked, deeply scratched or etched items from service. All glassware remains breakable.
Start with where and how the glassware will be used. This determines the appropriate material, vessel form, wall design, joint type, closure system and accuracy class.
Prioritise clear markings, easy handling and economical pack sizes. Consider reinforced-rim or documented heavy-duty products where rough handling is likely.
Choose the correct vessel form and confirm product-specific approval for the intended heating method, suitable supports and relevant thermal-shock guidance.
Choose calibrated volumetric products with a stated tolerance, accuracy class and standard. Use Class A or equivalent where the method or required uncertainty demands the tighter permissible error.
Check the complete bottle-and-closure system, chemical resistance, suitable headspace and documented sterilisation or autoclave compatibility.
Use products specifically designed and rated for the intended pressure or vacuum differential, with compatible joints, adapters, supports and traceable specifications.
For controlled or professional workflows, confirm the exact standard and edition, material grade, tolerance, calibration details, identification and certificate type.
Borosilicate 3.3 is a widely used laboratory glass grade because its low thermal expansion gives it better resistance to thermal shock than soda-lime glass. It is also highly resistant to water, many acids, salt solutions and many organic solvents, and its dimensional stability supports calibrated volumetric products.
Borosilicate 3.3 generally offers lower thermal expansion and better thermal-shock performance than soda-lime glass, but the finished product and intended method still determine suitability.
| Feature | What It Means | Buying Advice |
|---|---|---|
| Low Thermal Expansion | Borosilicate 3.3 expands and contracts relatively little with temperature change. | Useful where thermal cycling is expected, but only heat the exact item by a method for which it is designed. |
| Thermal-Shock Resistance | Lower expansion reduces thermal stress compared with soda-lime glass. | Thermal-shock resistant does not mean thermal-shock proof; avoid rapid or uneven temperature changes. |
| Chemical Durability | Good resistance to water, many acids, salt solutions and many organic solvents. | Check the exact chemical, concentration, temperature and contact time before use or storage. |
| Dimensional Stability | Low expansion supports stable dimensions in calibrated volumetric products. | Volumetric performance still depends on the product’s calibration, tolerance and reference temperature. |
| Finished-Product Suitability | The material and the finished vessel are not the same specification. | Check the exact product for heating, vacuum, pressure, autoclave and volumetric limits. |
Standards may apply to the glass material, finished product, volumetric testing or joint dimensions. Check the exact designation and edition stated in the product documentation; BS, EN, ISO, ASTM and DIN designations should not be treated as interchangeable.
Class A/AS products have tighter maximum permissible errors under the relevant standard; Class B products have wider permissible errors. Always check the exact standard, calibration mode and certificate supplied.
Tighter maximum permissible errors under the relevant product standard. Choose the tighter class where the method, quality system or required uncertainty demands it.
Wider maximum permissible errors, commonly up to twice the corresponding Class A limit where the applicable standard specifies this.
Check whether the product is calibrated to contain (In/TC) or to deliver (Ex/TD). Volumetric flasks and many measuring cylinders are In/TC; pipettes and burettes are normally Ex/TD.
Batch certificates, individual certificates and accredited calibration are separate purchasing options. A Class A marking alone does not confirm that an individual calibration certificate is supplied.
| Area | Examples |
|---|---|
| Material properties | ISO 3585:1998 — borosilicate glass 3.3; ASTM E438-92(2024) — glasses used in laboratory apparatus. |
| Beakers | ISO 3819:2015; ASTM E960-93(2026). |
| Volumetric flasks | ISO 1042:1998 — one-mark volumetric flasks. |
| Burettes and pipettes | ISO 385:2005 — burettes; ISO 648:2008 — single-volume pipettes; ISO 835:2007 — graduated pipettes. |
| Measuring cylinders | ISO 4788:2005 — graduated measuring cylinders. |
| Screw-neck bottles | ISO 4796-1:2016. |
| Testing and calibration | ISO 4787:2021 — testing capacity and use of volumetric instruments. |
| Ground joints | ISO 383:1976 — interchangeable conical ground joints. |
The correct form matters as much as the nominal capacity. Choose a vessel whose geometry, neck, base, joint and working volume suit the task and the equipment with which it will be used.
| Glassware | When to Choose It | What to Check | Important Note |
|---|---|---|---|
| Beakers | General mixing, pouring and product-approved heating | Griffin/low form for general work; Berzelius/tall form for more splash control; rim and spout quality | Graduations are normally approximate. |
| Conical / Erlenmeyer Flasks | Swirling, reactions and titrations | Neck width, capacity, heating suitability and any stopper or fitting requirements | Do not assume vacuum suitability. |
| Volumetric Flasks | Preparing solutions to a defined final volume | Calibration class, tolerance, standard, stopper and reference temperature | Do not use for direct heating. |
| Measuring Cylinders | Volume measurement where the stated tolerance is adequate | Class where applicable, scale readability, stable base and guard features for teaching use | For analytical standard solutions, use a volumetric flask unless the method specifically permits a calibrated mixing cylinder. |
| Laboratory Bottles | Reagent or media storage | Thread size such as GL 45, complete closure materials, usable headspace and any amber/low-actinic performance claim | Verify the specified wavelength protection for light-sensitive materials. |
| Round-Bottom Flasks | Even heating with a suitable mantle or bath, reflux and distillation | Capacity, joint designation and support arrangement | Use a suitable clamp, stand or heating system. |
| Joints, Adapters and Assemblies | Interchangeable specialist apparatus | Complete standard taper designation, compatible components and appropriate clips or PTFE joint clamps | 24/29 and 24/40 are not identical specifications. |
Durability depends on the complete design and condition of the item, not wall thickness alone. Uniform construction can help reduce local stress concentrations, while proper annealing reduces residual manufacturing stress and may extend service life.
Thermal-shock resistance is not the same as immunity to breakage. Heat gradually and evenly, use the correct support and avoid sudden hot-to-cold or cold-to-hot changes.
Match closure materials to the exact chemical and sterilisation method. The complete closure assembly matters: assess the cap body, liner or gasket, pouring ring, septum and any other components as a system rather than selecting only by the headline material.
Ground-glass stoppers provide an all-glass contact surface for selected applications, but they are not universally inert or gas-tight and may seize after prolonged storage, heating, contamination or exposure to alkaline residues.
These materials have different chemical and temperature limits. Check the exact chemical, concentration, contact time, temperature and sterilisation cycle for the complete closure assembly.
PTFE may be useful in demanding chemical applications, but suitability still depends on the whole closure system and the exact conditions of use.
PTFE/silicone septa can allow sampling without opening the container. Check chemical and temperature compatibility for the complete cap and septum assembly.
Use only where the glassware and closure are expressly suitable for the selected cycle. Ordinary screw caps should be loosened in accordance with the manufacturer’s instructions.
Only specially designed self-venting closure systems should be used closed during sterilisation. Never autoclave a sealed standard container.
Readability and compatibility affect both accuracy and day-to-day usability. Check the marking method, calibration mode, joint designation and the physical fit with the equipment already used in your laboratory.
Check the complete ground-joint designation before combining components. Compatible clips or clamps secure the assembly but do not create a vacuum or pressure rating.
Fired-on ceramic enamel, etched or diffusion-stained markings can offer better durability than ink that rubs off. Check suitability for the intended chemicals, cleaning agents and sterilisation cycles.
High-contrast white or amber graduations may suit different liquid colours. Lines and numbering should be crisp and evenly spaced.
Check whether the instrument is marked In/TC, to contain, or Ex/TD, to deliver. Volumetric flasks and many measuring cylinders are In/TC; pipettes and burettes are normally Ex/TD.
Standard taper joints support interchangeability only when the complete specification matches. Check both the nominal diameter and the ground length.
Confirm that vessel geometry and size suit the hotplate, mantle, bath, tripod, gauze or other support specified for the method.
Check the external dimensions and shape against cupboards, trays, drying racks, glassware washers and other storage or cleaning systems.
Use the least hazardous validated method and follow the manufacturer’s instructions, COSHH assessment and relevant safety data.
Wash with laboratory detergent, warm water and a soft, non-abrasive brush suitable for the vessel. Avoid abrasive pads and metal brushes, and make sure the brush cannot scratch the glass or become trapped.
Rinse with deionised water where required. Never mix cleaning agents, and collect solvent rinses through the correct waste stream.
Do not use chromic-acid cleaning mixtures or other aggressive oxidising cleaners unless an approved, documented laboratory procedure specifically requires them.
Autoclave only glassware and closures expressly suitable for the selected cycle. Loosen ordinary screw caps, leave appropriate headspace and use the specified slow-exhaust or cooling procedure.
Compatibility depends on the exact chemical, concentration, temperature, contact time, mechanical stress and any previous surface damage.
Remove chipped, cracked, deeply scratched or etched items from service. Where markings or calibration are critical, check that cleaning has not impaired readability or performance.
All glassware remains breakable. Inspect the item and check the exact product information before heating, sterilising, evacuating, pressurising or using it with demanding chemicals.
The updated guide treats lifecycle cost, repairability, replacement parts and disposal as part of the purchasing decision.
Glassware that looks similar can differ in material grade, calibration, wall design, annealing, joint specification and operating limits.
Durability depends on the complete design, uniform construction, annealing, vessel geometry, condition and intended heating method.
A borosilicate label does not automatically approve an item for flame, hotplate, mantle, bath, oven, autoclave, vacuum or pressure use.
Beakers, many flasks and bottles have approximate scales. Use calibrated volumetric ware when quantitative accuracy is required.
Check the cap body, liner or gasket, pouring ring, septum and other components against the exact chemical, temperature and sterilisation conditions.
Clips and clamps can secure compatible joints but do not create a pressure or vacuum rating.
Replaceable caps, liners, pouring rings, joint clips, stoppers, adapters and manufacturer-approved stopcock parts can reduce lifecycle cost.
Use the organisation’s waste procedure. Clean broken glass belongs in a designated rigid glass-disposal container; contaminated glass must follow the appropriate hazardous or sharps waste route.

Accessories and support equipment should be chosen around the vessel geometry and the manufacturer’s instructions for the exact method.
Use only where the exact glassware and local method permit flame heating, with the specified support and gradual, even heating.
View Bunsen BurnersUse the support specified for the heating method; the updated guide refers to ceramic-centred gauze where the manufacturer or local method specifies flame heating.
View Tripods & GauzeSupport round-bottom flasks, condensers, burettes and assemblies securely without overtightening or relying on a clamp to provide a pressure rating.
View Stands & ClampsChoose racks that fit the exact tube diameter and allow stable handling, preparation, storage and drying.
View Test Tube RacksCheck neck fit, chemical compatibility and temperature limits. Never heat a sealed or blocked system.

View MarkersBorosilicate glassware is laboratory glassware made from a silica-based glass containing significant amounts of boron trioxide. Borosilicate 3.3 is a widely used low-expansion laboratory grade.
Borosilicate 3.3 is a low-expansion glass grade with a mean linear expansion coefficient of approximately 3.3 × 10−6 K−1 between 20 °C and 300 °C.
It is widely used in school laboratories, but the exact product must still be selected for the intended task. A borosilicate label does not automatically mean an item is suitable for heating, autoclaving, vacuum, pressure or quantitative measurement.
Only when the exact item is expressly suitable for that heating method. Use the support specified by the manufacturer or local method, heat gradually and evenly, and never heat damaged or sealed glassware.
Only suitable flat-bottom glassware that is expressly designed for hotplate use should be heated this way. Check the product instructions and avoid localised hotspots and sudden temperature changes.
Borosilicate 3.3 has lower thermal expansion and generally better thermal-shock resistance. The finished product specification still determines whether either glass is suitable for a particular task.
Class A or AS glassware has tighter maximum permissible errors under the relevant product standard. The exact tolerance and calibration requirements depend on the product and standard.
Class B glassware has wider maximum permissible errors, commonly up to twice the corresponding Class A limit where the relevant standard specifies this.
Beaker graduations are normally approximate and should not be used where quantitative volumetric accuracy is required.
Only glassware and closures expressly suitable for the selected cycle should be autoclaved. Follow the manufacturer’s headspace, cap-loosening, slow-exhaust and cooling instructions, and never autoclave a sealed standard container.
Borosilicate 3.3 resists water, many acids, salt solutions and many organic solvents, but hydrofluoric acid, hot concentrated phosphoric acid and strong alkalis can cause appreciable attack.
Start from the practicals you need to support, then select the correct vessel forms and specifications for routine mixing, product-approved heating, quantitative measurement, storage and any specialist assemblies.
Choose a capacity that provides suitable working volume and headspace for the task, then check the vessel’s physical dimensions, spout, rim and any required heating specification.
Match capacity and neck size to the reaction or titration, check whether heating is required, and do not assume a standard conical flask is suitable for vacuum use.
Chipped, cracked, deeply scratched or etched items should be removed from service, particularly where heating, sterilisation, vacuum, pressure or demanding chemicals are involved.
That depends on the vessel and method. Common requirements include suitable supports, clamps, racks, closures, heating equipment, cleaning tools and the controls identified by the local risk assessment.
Before purchasing, make sure the specification addresses the following points from the updated PDF checklist.
