SFCA (surfactant-free cellulose acetate membrane) filter 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 is labeled with pore size and SFCA. Membranes are radiation sterilized, non-pyrogenic, non-cytotoxic and triton-free. The quick-disconnect sidearm accepts 1/4 to 3/8” tubing.

Use only with sterile bottles designed for vacuum use. Always use safety shield during vacuum procedures. The 0.2 µm size is for sterilization of aqueous solutions and culture media. The 0.45 µm filters are used for particle analysis, scintillation counting, prefiltration of aqueous solutions and general cytology. For laboratory use only, not for in vitro diagnosis or parenterals.
