Application area

Polycarbonate membranes are recommended for microscopic, chemotactic and cytological studies as well as aerosol filtration and subsequent analysis by X-ray fluorescence spectroscopy.

12.0 and 10.0 µm: general purification, prefiltration, purification and preliminary filtration of caustic fluids such as photoresist, concentrated acids, ester solutions

8.0 µm: as 12.0 µm: microfiltration of alcohols, of chemicals used as reagents

5.0 µm: in cytology, chemotaxis, and gravimetric analysis

3.0 µm: general microfiltration and purification; cytological evaluation of cerebrospinal fluids, chemotaxis, microfiltration of caustic fluids

2.0 µm: chemotaxis

1.0 µm: beer stabilization, prefiltration of serum, ultrapurification of fluids, ultrapurifications of caustic fluids, microfiltration of alcoholic solutions

0.8 µm: aerosol analysis, gravimetric analysis, wine stabilization, microscopic analysis of aerosols, yeasts and mould fungi

0.6 µm: biological determination of cells, wine and milk, plasmapheresis, particle analysis in caustic fluids

0.4 µm: biological determination of fluids, collection of asbestos fibres, dehydration and purification of cellular suspensions, immunology, particle analysis of caustic fluids, analysis of yeast, mould fungi and silicon oxide (silica)

0.2 µm: general sterile filtration, immunology, sterile filtration of caustic fluids

0.1 and 0.08 µm: virus filtration

0.05; 0.03 and 0.015 µm: virus and protein filtration

Product specification

Membranes can stand permanent temperatures of +140 °C (air or steam) for an indefinite time allowing repeated autoclaving. Polyester membranes are hydrophilic with chemical resistance similar to PTFE. Polyester membranes are recommended for filtration of HPLC solutions and samples which are to be analyzed by HPLC.
