DURAN® Filter Disc, sintered glass, edge not fused, centred, surfaces untreated, Ø 30 mm, Porosity 5

  • Manufactured from borosilicate glass 3.3
  • Edge non-melted and centred, surfaces untreated
  • Successful work through the correct choice of porosity (The largest pore size should be slightly below the grain size of the smallest particles still to be separated).
  • Available in 6 different porosity classes
  • Glass articles for further processing

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. A prerequisite for successful work with glass filters is the selection of the right porosity. It is important to select a filter whose largest pore size is slightly below the grain size of the smallest particles still to be separated.
