Simax Test Tubes with Rim – 150 × 16mm, 1.2mm Wall (Box of 100)

The Simax Rimmed Test Tubes (150 × 16mm) are part of the trusted Simax 3.3 borosilicate glass test and boiling tube range, engineered for reliable performance in school and educational laboratories. Each tube features a rolled rim and uniform wall thickness, ensuring safe handling, consistent heating, and long‑lasting durability.

With a medium‑duty 1.2mm wall thickness, these test tubes provide additional strength for more demanding experiments while maintaining excellent heat transfer. Borosilicate glass is highly resistant to thermal shock and chemical attack, making these tubes ideal for heating, boiling, and repeated classroom use with a wide variety of chemicals.

Supplied in a convenient box of 100, these longer test tubes are particularly well suited to experiments requiring larger sample volumes or clearer visual demonstrations. The transparent glass allows students to easily observe reactions, colour changes, gas evolution, and precipitate formation.
