        CA Filtration Membrane

        GVS Cellulose Acetate (CA) Filtration Membrane is a supported, hydrophilic membrane that exhibits naturally low protein binding.

        Composed of cellulose acetate internally supported by an inert polyester web, resulting membrane has dimensional stability.

        This provides higher throughputs than competitor offerings and reduces the number of filter changes needed during the filtration of proteinaceous solutions.

        It is ideal for use in filtration applications where maximum recovery of protein is critical.

        Properties

        GVS CA Membrane is available in roll widths from 1 inch (2.54 cm) to 13 inches (33 cm), as well as in sheets and disks that can be customized to meet your application and size requirements.

        Features & Benefits

        • Superior strength to withstand aggressive handling or use with automated equipment without breaking or tearing;
        • Low protein binding minimizes retention of proteins in solution;
        • Low extractable ensure tests will be clean with consistent results;
        • Lot-to-lot consistency ensures consistent flow and diffusion rates for dependable results every time
        • Non-lysing of cells prevents contaminations of critical solutions;
        • Passes USP Class VI Toxicity testing, ensuring suitability for use in medical devices;
        • The material in this membrane are FDA approved for food contact under the applicable regulations in 21 CFR.
