Corning 430756 Polystyrene Vacuum Filter/Storage Bottle System, Graduated, Sterile, Cellulose Nitrate Membrane, 0.22 Micron, 250mL Capacity (Case of 12)

This new vacuum filter/storage bottle system is designed for filtering and storing cell culture media, biological fluids, and other aqueous solutions. The new system consists of a 250mL polystyrene receiver bottle and filter funnel with a 0.22µm pore size 19.6sq cm area CN membrane and a polyethylene neck adaptor with hose connector. Cellulose nitrate (CN) membranes are good for filtering buffers where protein binding is not a concern. The receiver bottle features easy grip sides for improved handling. Additional storage bottles can be purchased to increase capacity. Bottle cap is supplied sterile and individually packaged. An angled hose connector simplifies vacuum line attachment. Each system has the membrane material and pore size printed on the unit and is color-coded by membrane type for easy product identification.
