DURAN® filter plates edge unfused and centered, surface unmachined, D.30 mm, POR.4

DURAN® filter plate, rim unfused, Ø 30 mm, porosity 4 Sintering glass powder with a specific particle size distribution produces a porous, solid body. In the form of plates and candles, these bodies are used as filter material. Made of DURAN® (borosilicate glass 3.3). They are ideal for separations with, for example, strong acids or alkalis and thus offer advantages over other materials such as plastic or paper. Available in 6 different porosity classes each according to ISO 4796 as well as ASTM EI28-99. Suitable for vacuum filtration with a maximum resulting pressure difference of 1 bar. Special features and advantages: Rim unfused and centered, surfaces unmachined Successful work due to the correct choice of porosity (The largest pore size should be slightly below the particle size of the smallest particles still to be separated) Available in 6 different porosity classes according to ISO 4796 as well as ASTM EI28-99. Glass articles for further processing Application: Suitable for vacuum filtration with a maximum resulting pressure difference of 1 bar.
