Product Overview
By default, tests are carried out at normal pressure. The conduct of tests under vacuum (negative pressure) can have significant effects on the reaction sequence. In order to be able to observe these effects in the rough and fine vacuum range, a vacuum experiment plate and a bell jar (also called air pump bell) are required.

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.
