Cellulose Acetate Membrane

Product code:


Johnson Test Papers’ CA (cellulose acetate) membrane filters are made of pure cellulose acetate which has been altered to provide the lowest binding filters possible for researchers. When compared to alternative offerings, these filters provide large throughput and reduce the need to change filters when filtering protein solutions. CA membrane filters are exceptionally strong and exhibit minimal binding properties, making them suitable for applications where maximum recovery of proteins is essential such as filtration of proteins and enzymes, tissue culture media sterilisation, cold sterilisation and biological fluid filtration.

In order to prevent damage when handled or creased, CA membrane filters are produced using a special impregnation process that is internally supported by a polyester web. These unique processes generate filters guaranteed to give reliable performance. CA membrane filters have unparalleled dimensional stability after autoclaving or steam sterilisation and are unaffected by temperatures up to 135 °C with a burst strength of 130 psi, offering invariable performance with a uniform pore size and consistent flow rates.
