Inlet: Female Luer-Lok™, outlet: Male Luer slip
Polypropylene housing with ID colour rings
Pore size and membrane type printed on unit
Polyethersulfone (PES) membranes:
Highest throughput and lowest clogging
Low binding
Most commonly used general purpose membrane
Surfactant-Free Cellulose Acetate (SFCA) membranes:
Low protein binding, lower extractables than standard CA
Good for cell culture fluids and cellular solutions
Polypropylene housings with blue colour rings
Cellulose Acetate (CA) membranes:
Some protein binding and extractables
For sterile filtration and clarification of: buffers, aqueous solutions and reagents
Polypropylene housings with red colour rings
Nylon membranes:
Naturally hydrophilic, low extractables, some protein binding
Useful for alcohols, cryoprotectants such as DMSO and with aqueous/biological and weak solvents
Polypropylene housings with pink colour rings
PTFE membranes:
Naturally hydrophobic
Excellent for HPLC/GC solvent filtration. Ideal for sterile venting of air or other gases during filtration
Polypropylene housings with white colour rings
