DPS Double Layered PES Cartridge FIlters
PNC Membrane Filter Cartridges are sterilizing grade cartridges with charged Nylon 6,6 membrane. The nylon membrane used in these cartridges is positively charged for enhanced retention of particles below the rated pore size of the filter. Nylon cartridges see broad service in sterile fill applications in SVPs and as bioburden management filters in LVPs. Media preparation and service liquid filtration are other common applications for this cartridge. Positively charged nylon is particularly suited for endotoxin removal in water systems. Nylon is also used for filtration of solvents because of its broad compatibility and low level of extractables. Positively Charged Nylon 6,6 Membrane
