Product Overview
Glass powder with a certain particle size distribution results in a porous, solid body. These bodies are used as filter material in the form of plates and candles. Made of DURAN® (borosilicate glass 3.3). They are ideally suited for separations with strong acids or alkalis, for example, and thus offer advantages over other materials such as plastic or paper. Available in 6 different porosity classes according to ISO 4796 as well as ASTM EI28-99.
Suitable for vacuum filtration with a maximum resulting pressure difference of 1 bar.
Suitable for vacuum filtration with a maximum resulting pressure difference of 1 bar.
Specifications
| h (mm) | 3.8 |
| 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. |
