Fiberglass Prefilters

Microclar fiberglass prefilters are manufactured with 100% borosilicate glass, free of chemically inert binding agents and also with micro-fiberglass with binding agents. These depth filters allow fast filtration speed and high retention of particles. They are recommended for air and water contamination analysis and as prefilters for membranes.
