VENTECH® LOW EXPANSION BOROSILICATE GLASS
Laboratory work requires apparatus made in a Borosilicate 3.3 expansion glass which maintains maximum inertness to widest range of chemical substances, withstand thermal shock, high temperature without deforming and resilient enough to withstand the normal laboratory handling, washing and sterilizing processes.
VENTECH® is the trade name of such a glass.
CHEMICAL COMPOSITION
The approximate composition of the borosilicate glass used by us is as follows:
- SiO2 - 81%
- B2O3 - 13%
- Na2O - 04%
- Al2O3- 02%
