Prefilter in glass microfiber (GF/GMF): Hydrophilic glass microfiber membrane, which can be used for solutions with high particle load or high viscosity, e.g. soil samples and fermentation media. The high chemical resistance of GF glass microfiber allows the filtration of aggresive solutions and solvents.
Polyvinyldifluoride (PVDF): Hydrophilic membrane, use for aqueous polar and slightly non-npolar solutions. The membrane has a very low protein binding, and is ideal for use with biological macromolecules, water soluble oligomers, and polymers. Suitable for high flow rates.
