Osmonics* PreSep* Glass Prefilters

Biologically inert and highly resistant to oxidizing agents and weak acids.
Type G15 Glass Fiber Prefilters with Binders
Nominal pore size (0.5 micrometer). High retention efficiency. Limited dirt-handling capacity. Protection of 0.2 micrometer to 0.8 micrometer final filters. Autoclavable.
Type G20 Glass Fiber Prefilters with Binders
Nominal pore size (1.0 micrometer). Average retention efficiency. High dirt-handling capacity. Protection of 0.8 micrometer final filters and larger pore sizes. Autoclavable.
Type G25 Glass Fiber Prefilters with Binders
Nominal pore size (1.0 micrometer). Average retention efficiency. Highest dirt-handling capacity. Recommended for solutions with heavy contaminate loads. Protection of 0.8 micrometer final filters and larger pore sizes. Autoclavable.
Type G40 Glass Fiber Prefilters without Binders
Nominal pore size (1.0 micrometer). Average retention efficiency. Highest dirt-handling capacity. Recommended for solvent filtration, gravimetric analysis, contamination analysis of waste water and industrial effluents. Autoclavable.
