PES Filter

Supor EKV filters are 0.2 micron rated validated sterilizing-grade membrane filters. Utilizing a laid-over-pleat membrane geometry for high flow rates and throughput performance, they are designed for the most cost effective filtration of a wide range of liquids such as buffers, tissue culture media, and others. A PES membrane ensures very high compatibility over the whole pH range plus very low protein binding to ensure the maximum transmission of active ingredients.

Pall’s AB style filters are disposable cartridges to be used with stainless steel housing assemblies, most suitable for medium to large scale manufacturing operations (100 L to >1000 L).

A validation package for Supor grade EKV filters supports the assurance of safety within your process.
