DLHPVHBR/LHPVHBR Sterilizing-Grade Liquid Filter
Cobetter's DLHPVHBR/LHPVHBR series filter cartridge is made of hydrophilic and positively-charged PVDF membrane. PVDF's unique very low protein adsorption performance makes it particularly suitable for filtration of culture fluids, biological reagents, sterile vaccines, etc. At the same time, DLHPVHBR/LHPVHBR has low leachables, wide chemical compatibility, and very excellent temperature resistance.
