Laboratory Boiling Tubes – Heavy‑Duty 150 × 24mm with Rim (3.3 Borosilicate Glass, Box of 50)

These robust Labglass heavy‑duty boiling tubes are manufactured from premium 3.3 borosilicate glass, offering outstanding resistance to heat, thermal shock, and chemical exposure. Designed specifically for high‑temperature work, they provide a safe and reliable solution for demanding experiments in school science laboratories.

Each boiling tube measures 150mm in length and 24mm in diameter, making them ideal for larger‑volume reactions and boiling tasks. The reinforced rolled rim allows for safer handling with tongs or clamps, while the uniform heavy‑duty wall thickness of approximately 1.8mm delivers excellent durability for repeated heating cycles.

Supplied in a practical box of 50, these boiling tubes are well suited to busy classrooms, prep rooms, and science departments requiring long‑lasting, high‑capacity laboratory glassware.
