PreFlow™ Cartridges

Pall PreFlow filters have been expressly designed to bring a significant improvement to prefiltration technology. The filter media utilized is based on our expertise in manufacturing rugged resin-bonded glass fiber composites. These sanitary-style filter cartridges are manufactured with pleated high-area construction for long service life. PreFlow filters are designed to reduce costs and are especially suited for biological prefiltration applications, including serum, vaccines, tissue culture media, and protein solutions.
