Use Corning® Sterile Bottle-Top Vacuum Filters to filter cell culture media, biological fluids, and other aqueous solutions. They are designed to work well with glass and polystyrene media bottles. Plus, these filters have the membrane material and pore size printed on them, and they are color coded by membrane type for easy product identification. Each includes a membrane filter, graduated clear polystyrene funnel, and polyethylene neck adapter with angle hose connected, which simplifies vacuum line attachment. Filters are provided individually packaged, Gamma sterilized, and certified non-pyrogenic.

Choose from Filter EF8259B, featuring a 45mm neck diameter to fit wide mouth media bottles and polyethersulfone (PES) membrane, and Filter EF8251D, featuring a 33mm neck diameter to fit narrow mouth media bottles and cellulose acetate (CA) membrane.
