Beschreibung

General description

Polystyrene body with graduations. Membrane is polyethersulfone (PES), offering higher aqueous flow rates, lower extractables (no wetting agents), lower protein binding, and greater strength, capacity and chemical resistance than cellulose acetate, nitrocellulose or nylon. Sterile.

Application

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

Features and Benefits

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.
