SFCA (surfactant-free cellulose acetate) membrane filters are much cleaner than standard cellulose acetate and are designed for vacuum filtration with glass media bottles
Polystyrene bottle-top design features molded graduations and a support plate that minimizes foaming and eliminates the need for a separate filter pad. Filter unit screws directly onto media bottles. Yellow collar filter cup is labeled with lot number, catalog number, pore size, and expiration date. Certified radiation-sterilized, nonpyrogenic, and noncytotoxic. The quick-disconnect sidearm accepts 1/4–3/8" tubing.
Note: Use only with sterile bottles designed for vacuum use. Always use safety shield during vacuum procedures. For laboratory use only, not for in vitro diagnosis or parenterals.
Use the 0.2µm size for sterilization of aqueous solutions and culture media. Select the 0.45µm size for particle analysis, scintillation counting, prefiltration of aqueous solutions, and general cytology.
