Corning 431155 Polystyrene Vacuum Filtration System - 150mL Sterile Graduated Bottle with 0.45μm Cellulose Acetate Membrane (Case of 12) - Ideal for Laboratory Sample Preparation, Media Filtration & Sterile Storage

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 150mL polystyrene receiver bottle and filter funnel with a 0.45µm pore size 13.6sq cm area CA membrane and a polyethylene neck adaptor with hose connector. Cellulose acetate (CA) membranes provide fast flow rates and low protein binding and are good for filtering cell culture media. 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. 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). Individually packaged, sterile, and certified nonpyrogenic. This is the suggested replacement for Corning Item Number 430945. Sterile. Graduated. Material: Polystyrene. Bottle Capacity: 150mL.
