Simax Test Tubes with Rim – 100 × 12mm, 1mm Wall (Box of 100)

The Simax Rimmed Test Tubes (100 × 12mm) are high‑quality laboratory test tubes manufactured from premium 3.3 borosilicate glass, designed to deliver excellent performance and durability in school and educational laboratories. Featuring a rolled rim and uniform wall thickness, these tubes provide safe handling and consistent results during experimental work.

With a medium‑duty 1mm wall thickness, these test tubes are ideal for heating, boiling, and mixing small volumes of liquids. Borosilicate glass offers exceptional resistance to thermal shock and chemical corrosion, making these test tubes suitable for repeated use with a wide range of laboratory chemicals.

Supplied in a convenient box of 100, these Simax test tubes are well suited to class sets, practical investigations, and demonstrations. The clear glass construction allows students and teachers to easily observe reactions, colour changes, and precipitate formation.
