Hydrophilic CA membrane filter rolls

These Hydrophilic CA Membrane Filter Rolls Cellulose Acetate membrane filters provide superior throughput and reduce the need for filter changes; effectively decreasing both cost and process times. The hydrophilic nature and durable physio-chemical properties of these membranes support a wide range of samples and applications, including: proteinaceous solutions, rigorous or automated processes, and thermal/pressure intensive conditions. These filters are produced from an exclusive impregnation process, ensuring pore-size and material uniformity for consistent flow rates, analytical precision, and repeatable results. Additionally, our Hydrophilic CA Membrane Filter Rolls are completely un-compromised up to 135 °C (275 °F), retaining dimensional strength throughout both autoclave and steam sterilization.

*Composed of cellulose and triacetate, these filters exhibit low static charge and high strength
*May be sterilized repeatedly without loss of integrity or change in bubble point
*Extremely low aqueous extractables
*Good resistance to heat and low molecular weight alcohols
*Use for filtration of enzyme solutions, diagnostic cytology or receptor binding studies
