Nalgene^® bottle-top sterile filter units are suitable for the filtration of cell culture media, additives, serum, and buffers.

Nalgene^® bottle-top sterile filter units have the following benefits:

• Polyethersulfone (PES) membrane is best suited for tissue culture.
• Faster results and less waiting time.
• Non-pyrogenic and endotoxin free.
• PES exhibits low protein binding, resulting in low chances of loss of protein from media.
• PES is hydrophilic and thus does not require external wetting agents or surfactants.
• PES offers higher aqueous flow rates.
• PES has greater strength, capacity, and chemical resistance than cellulose acetate, nitrocellulose, or nylon.
• Polystyrene body with graduations.
