GVSModel CA -Cellulose Acetate Filtration Membrane

SHARE

GVS Life Sciences 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, the resulting membrane has dimensional stability. This provides higher throughputs than competitor offerings and reduces the amount of filter changes needed during filtration of proteinaceous solutions. It is ideal for use in filtration applications where maximal recovery of protein is critical. GVS Life Sciences CA Membrane is available in roll widths from 25 mm (1 in) to 30 cm (12 in), as well as in sheets and disks that can be customized to meet your application and size requirements.
