General description

Corning square bottle-top vacuum filter systems support a higher capacity cellulose nitrate (CN) membrane for greater filtering performance. These new bottle/filter systems are designed for filtering and storing cell culture and/or tissue culture media, biological fluids and other aqueous solutions.

• Cellulose nitrate (CN) membranes are good for filtering buffers where protein binding is not a concern.
• Receiver bottles feature easy grip sides for improved handling.
• Additional storage bottles can be purchased to increase capacity.
• Bottle caps are supplied sterile and individually packaged.
• Angled hose connector simplifies vacuum line attachment.
• Individually packaged, sterile and certified nonpyrogenic.
• Each system has the membrane material and pore size printed on the unit and is color-coded by membrane type for easy product identification.
• Expiration date appears on the filter funnel and shipping boxes.
• Expiration date of the membrane is three years from the time the product is manufactured.

Corning® bottle-top vacuum filter systems feature a square filter support for improved filtering performance. These bottle top vacuum filter systems are designed for filtering and storing cell culture and/or tissue culture media, biological fluids and other aqueous solutions. The systems consist of a polystyrene receiver bottle and filter funnel with filter membrane and a polyethylene neck adaptor with hose connector.
