NEW! Over the next several months Corning is introducing a new square filter support with a higher capacity Polyethersulfone (PES) membrane for greater filtering performance. Continue ordering the same catalog numbers you are currently using and the new improved filters will show up in your lab as soon as they are available. These new Corning® Bottle Top Vacuum Filters are designed for use on glass or polystyrene media bottles to filter cell culture media, biological fluids and other aqueous solutions. These filters consist of a 500mL polystyrene filter funnel with a 0.22µm pore 33.2m² PES membrane and a 45mm diameter polyethylene neck adaptor with hose connector.

• Fits plastic or glass media bottles with 45mm neck sizes. 
• Polyethersulfone (PES) membranes provide the fastest flow rates, the lowest protein binding and low extractables and are best for filtering cell culture media. 
• 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.
