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

The Simax Rimmed Test Tubes (100 × 16mm) are part of Simax’s premium 3.3 borosilicate glass test and boiling tube range, designed for outstanding performance in educational and laboratory environments. Featuring a rolled rim and uniform wall thickness, these test tubes provide consistent, reliable results during heating and experimental work.

With a medium‑duty 1.2mm wall thickness, these test tubes offer enhanced strength while still allowing efficient heat transfer. The high‑quality borosilicate glass delivers excellent thermal shock resistance and chemical durability, making these tubes ideal for boiling, heating, and repeated use in busy school laboratories.

Supplied in a practical box of 100, these larger‑diameter test tubes are well suited to class sets, demonstrations, and experiments requiring slightly larger sample volumes. The clear glass construction allows for easy observation of reactions, colour changes, and precipitates.
