Product Overview
DURAN® cylinders with a round bottom are convincing due to their good wall thickness distribution and enable the cost-effective production of reaction vessels with reproducible geometry.
For pressure resistance, please refer to our notes in the technical appendix of the laboratory glassware catalogue.

For glass articles which deviate from the original form due to further processing, the permissible operating data must be determined in accordance with the technical rules and regulations.

Specifications
Wall Thickness s (mm) 5.5
Boro 3.3 Borosilicate glass 3.3 has a very good chemical resistance, virtual inert behavior, a high maximum usage temperature, high light transparency and minimal thermal expansion. Borosilicate glass 3.3 has a linear coefficient of expansion of 3.3 × 10−6 K−1 at 20 °C. It also conforms to the requirements of a USP/EP/JP Type 1 neutral glass suitable for use by the pharmaceutical industry. The properties of DURAN® are specified to ISO 3585 and ASTM-E438 Type 1 Class A.
