DESCRIPTION
Versapor™ acrylic copolymer membrane disc filters, a Pall Life Sciences product, are designed for prefiltration of difficult-to-filter solutions and serum.
Reduces clogging of final filters. Can be used upstream of a sterilizing filter for viscous solutions.
Strong and flexible while both wet or dry.
Excellent throughput with high liquid flow rates at low differential pressures.
