Millipak Disposable Filter Units
Stacked disc filters designed for the removal of particles and microorganisms from liquids and gases.
Description
Millipak disposable filter units are stacked disc filters designed for the removal of particles and microorganisms from liquids and gases. The stacked disc design allows minimal hold-up volume and particle shedding, making Millipak units ideally suited for high value-added applications. All Millipak units are made with Durapore PVDF membranes, providing high flow rates and throughputs, low extractables, broad chemical compatibility and the lowest protein binding of any membrane available.
Millipak units are available in 0.1 µm, 0.22 µm and 0.45 µm pore sizes and a variety of inlet and outlet connections. Five different stack sizes allow optimum flexibility for easy scale-up and system sizing. For added convenience, some Millipak units are supplied sterile. Each unit is 100% integrity tested during manufacture to guarantee integrity.
For traceability and easy identification, each Millipak unit is labelled with its catalogue number, lot number, pore size and serial number.
Typical Applications
● Sterile filtration of parenterals, diagnostics, and buffers
● Sterile filtration of media and biologicals
● Point-of-use filter for high purity water
