NALGENE 157-0020

Conduct vacuum filtration and single-use biological work requiring sterile filtration, prefiltration or clarification of aqueous solutions in the lab or field with Thermo Scientific™ Nalgene™ Rapid-Flow™ Sterile Disposable Filter Units with SFCA Membrane. Surfactant-Free Cellulose Acetate (SFCA) membranes have lower extractables than standard (CA) membranes.

Features

• Upper chamber separates from storage bottle for easy access to filtrate
• Upper chamber clearly marked with pore size, membrane type, catalog number, lot number and expiration date (except 115mL size)
• Leakproof (except 115mL sizes) screw cap eliminates pH shift in storage bottle to provide longer life for stored media
• Padless membrane support minimizes foaming of proteinaceous samples
• Non-pyrogenic and non-cytotoxic
• Gamma radiation-sterilized and individually bagged for a 5-year sterile shelf life

Surfactant-Free Cellulose Acetate Membranes (SFCA)

• Low protein binding, excellent flow rates, little or no loss of specific proteins
• No wetting agents to affect sensitive cell culture lines
• Yellow collar for easy identification
• Much lower extractables than standard CA membranes
