The glass fibre structure of PISCO sintered filters results in a more abrasion resistant surface. Being fused together on a greater surface area, the particles do not detach from the filter body as easily as spheroid granules. Being made entirely of heat resistant borosilicate glass, resistance to thermal shok and chemical attack is unimpaired. PISCO sintered filters are manufactured from 100% low expansion borosilicate glass grains and cleaned till it is 100% chemical pure.

Operating Pressure Limit Of Sintered Glass Buchner Funnel(for filter purpose) : Fritted sintered glassware is designed primarily for vacuum filtration or for gas flow at relatively low pressure. If used for pressure work the maximum differential on the disc should not exceed 15 psi. PISCO manufacture a very wide range of sintered glass filtration sets with different models/sizes and porosities. PISCO sintered filters are extensively used for the filtration of both liquids and gases. Apart from these range, we can fabricate any special type/model sintered filter apparatus according to customer's design and specification.
