Introduction of PVDF membranes
PVDF membranes (polyvinylidene difluoride) are particularly microporous membranes, can be prepared to exhibit high efficiency for particle removal. There are Hrophobic PVDF membrane and Hydrophilic PVDF membrane. Most is Hrophobic PVDF membranes with a pore size of 0.2 or 0.45 µm. Proprietary alterations in the pierce PVDF membrane make it more resistant to discoloration which [...]
Knowledge of Hydrophobic Glass Fiber Membrane Filter
Glass fiber filters are manufactured from 100% borosilicate glass. Glass fiber filters are manufactured by Membrane Solutions. Hydrophobic glass fiber membrane filter is a barrier to airborne microbial contaminants, and its surface is modified so that the medium may be used in vent applications exposed to extremely viscous solutions.
