Labglass Test Tubes with Screw Caps – 16 × 100mm (Box of 24) [2769]

These Labglass Test Tubes with Screw Caps are high‑quality laboratory essentials, ideal for routine use in school science laboratories. Manufactured from 3.3 borosilicate glass, the tubes offer excellent thermal and chemical resistance, making them suitable for heating, mixing, and storing a wide range of substances used in educational experiments.

Each test tube features a round bottom and is supplied with a secure bakelite screw cap fitted with a rubber liner. This design helps to reduce spillage and contamination during storage or gentle mixing. The glass tubes and bakelite caps are autoclavable, supporting good laboratory hygiene, although the rubber liner should not be autoclaved.

With dimensions of 16 × 100mm, these test tubes are easy for students to handle while still offering sufficient volume for common classroom investigations. Supplied in a convenient box of 24, they are well suited to group work and repeated use in busy teaching environments.
