- Foods and Beverages
- Process Water Systems
The filtration of process water installations for removal of general contamination and resin fines. The naturally occurring zeta-potential of glass fibre in aqueous solutions makes the MicrofilTM GP filter ideal for removing submicronic particles.
- Pharmaceuticals and Bioprocessing
The excellent dirt holding capacity of the Microfil™ GP makes it an ideal choice for prefiltration of complex biological fluids (e.g. cell culture media).
- Fine Chemicals
The filtration of high grade chemicals including solvents, reagents, photographic emulsions, inks and paints.
