Whatman mixed cellulose ester membranes are composed of cellulose acetate and cellulose nitrate. These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters.

By choosing an ELGA water purification system, you are making an investment in quality, reliability and value.

Syringe filters are available with a choice of membrane type: Polyethersulfone (PES) for low protein binding and faster flow rates; surfactant-free cellulose acetate (SFCA), with or without prefilter, for lowest protein binding; Polytetrafluoroethylene (PTFE) for chemical resistance; regenerated cellulose (RC) – the best choice for DMSO compatibility; and nylon (NY) which is hydrophilic, surfactant-free and lowest extractable.
