Nalgene filtration units -

Complete filter units Nalgene

Membranes available:
• CA or SFCA: cellulose acetate or surfactant-free cellulose acetate, colour code yellow;
• CN: cellulose nitrate, colour code green;
• Nylon, colour code red;
• PES: polyethersulfone, colour code blue;
• PES FASTER: Supor MachV rapid filtration membrane, asy mmetrical, low protein binding.

Applications:
• PES: for cell culture media, low protein binding, low extractables, no external wetting agent, rapid filtration
• SFCA: low protein binding, no wetting agent
• CN: for the general filtration of buffers or solutions
• Nylon: no wetting agent, lowest level of extractables, excellent resistance to alcohol
