GVS Cellulose Acetate (CA) Filtration Membrane is a supported, hydrophilic membrane that is naturally low binding. It is ideal for use in filtration applications where maximal recovery of protein is critical.

GVS CA Filtration membranes are composed of pure cellulose acetate that is internally supported by an inert polyester web. This web gives each membrane exceptional strength to prevent cracking, tearing, breaking and distortion when handled or creased. The resulting membrane has dimensional stability that can withstand autoclaving or steam sterilizing leaving the membrane unaffected in temperatures up to 135°C (274°F). The exceptional dimensional strength and low binding characteristics of GVS CA Filtration Membranes provides higher throughputs than competitive offerings and reduces the amount of filter changes needed during proteinaceous solution filtering. Its uniform pore size and consistent flow rates ensure reliable performance.  

Features:

Superior strength: Can withstand aggressive handling or be used with automated equipment without breaking or tearing

Low extractables: Ensures tests will be clean with consistent results

Hydrophilic: Wets out rapidly

Lot-to-lot consistency: Quality checks ensure consistent flow and diffusion rates for dependable results every time

Nonlysing of cells: Prevents contamination of critical solutions

Autoclaving and steam sterilizing
