The application of the frit depends on the size of its pores. According to ISO standard 4793, man distinguish seven pore sizes refers to the filtration purpose:

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.
