Porous AISI 316L stainless steel filters
AmesPore® candle filters and porous tubes are long, cylindrical filters with thin walls, i.e. they have a high length/diameter ratio.
The material used for these filters is AISI 316L stainless steel. They are made by isostatic compaction of powder in a flexible mould with the negative shape of the part, and then sintered.The pore size is adjusted by changing the compaction pressure and/or the particle size of the powder.
