Combustion Tubes made of borosilicate 3.3 glass that can withstand high temperature fluctuations and thermal shocks, which is ideal for the controlled combustion of substances.

• With superior durability and chemical resistance
• 30 cm in length
• Open on both ends
• Used for the oxidization and reduction of chemical substances in a furnace

Often use for chemical reactions that involve heating a substance in the presence of oxygen or other gases. Tubes measure 30 cm long.

Eisco borosilicate glass has the following heat tolerances:
- Strain point 515 °C
- Annealing point 565 °C
- Softening point 820 °C
