ISO-identification Identification Diameter of pores in µm Applications of the frits
P 500 POR 00 / G 00 250-500 Filtration of coarse precipitates, gas distribution in liquids with low gas pressure.
P 250 POR 0 / G 0 160-250 Filtration of coarse precipitates, gas distribution in liquids with low gas pressure.
P 160 POR 1 / G 1 100-160 Coarse filtration, gas distribution with higher pressure.
P 100 POR 2 / G2 40-100 Preparative fine filtration, preparative work with crystalline precipitates, diffusion of gases in liquids.
P 40 POR 3 / G 3 16-40 Analytical filtration, analytical work with medium precipitation, preparative work with fine precipitates, diffusion of gases in liquids.
P 16 POR 4 / G 4 10-16
Analytical fine filtration, analytical and preparative work with very fine precipitates, very fine gas distribution in liquids by means of pressure, shut-off valves for mercury.
P 1,6 POR 5 / G 5 1-1.6
Ultrafine filtration, bacteriological filters, filtration of larger microorganisms, extremely fine gas distribution in liquids by means of high pressure.
