Corning® Tube-Top Vacuum Filter Systems

Corning® Tube Top Filter Systems are designed for the filtration of cell culture media, biological fluids, and other aqueous solutions. The systems consist of a 150 mL polystyrene filter funnel with 50 mm diameter 0.22 μm or 0.45 μm cellulose acetate membrane, a 50 mL polypropylene receiver centrifuge tube and a polyethylene neck adaptor and hose connector.
  • Minimizes unnecessary transfers by filtering directly into 50 mL centrifuge tube.
  • Includes two centrifuge tube stands with each case.
  • Cellulose acetate (CA) membranes provide fast flow rates and low protein binding and are good for filtering cell culture media.
  • Polypropylene centrifuge tube is supplied with an individually wrapped cap for storage.
  • Individually packaged, sterile, certified nonpyrogenic.
  • Expiration date appears on the filter funnel and shipping boxes. Expiration date of the membrane is three years from the time the product is sterilized.
