Nalgene PES: The best choice for cell culture Polyethersulfone (PES) is the ultimate tissue culture membrane. It’s fast and clean. PES is low protein binding, so there is less chance of removing critical protein from your media. It is hydrophilic, so no external wetting agents or surfactants are needed, resulting in low extractables. And it is fast, so you spend less time waiting. WARNING! All NALGENE Filterware is for research use only, not for in vitro diagnosis or parenterals. *CAUTION: Use only sterile bottles designed for use with vacuum. Always use safety shield during vacuum procedures.
