Available in Two Types
Glass vacuum filter holders are available in two types which differ only in the filter support. This support contains either a glass frit or a PTFE-coated stainless-steel screen and an underdrain screen. The filter supports may only be changed as a unit. Because of the particularly even distribution of particulates of the membrane filter surface, filter supports with glass frits are preferred for use in particulate analysis. Filter supports with a PTFE-coated screen are mainly used for clarifying or sterile filtration of liter volumes
