47mm diameter filter discs for benchtop membrane qualification studies. 

Supor® grade EAV membrane filters are 0.2 micron-rated filters validated to achieve a titer reduction of 6 LRV when challenged with B. diminuta (ATCC 19146). Incorporating a single layer of highly asymmetric Supor polyethersulfone filter membrane, Supor EAV filters deliver outstanding flow rates and throughput to blockage. They are suited to the bioburden control filtration of buffers and dilute protein solutions or the prefiltration of high-particulate-containing biological process streams to extend the service life of more critical filters sterilizing-grade or mycoplasma control filters downstream.
