SFCA (surfactant-free cellulose acetate) membrane filters are much cleaner than standard cellulose acetate and are designed for vacuum filtration with glass media bottles.

• Certified radiation-sterilized, non-pyrogenic, and non-cytotoxic
• Quick-disconnect sidearm accepts ¹/₄ to ³/₈" tubing
• Use the 0.2 µm size for sterilization of aqueous solutions and culture media

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.

Select the 0.45 µm size for particle analysis, scintillation counting, prefiltration of aqueous solutions, and general cytology.
