Product Overview
One of the most important separation methods in the laboratory environment is filtration, which is used to separate or clean different media. For this working method, filters are required which are selected according to the application with regard to size and porosity. Filter funnels are filters that are used for solid-liquid separation by means of vacuum. Filter tubes have a glass sintered disc bottom which serves as a filter medium and does not require any further filter paper.

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.
