PALL 66394 Versapor Acrylic Copolymer 1200 Membrane Disc Filter, 1.2 µm - 47 mm (100/pkg)

The Pall 66394 Versapor membrane is primarily used for prefiltration and clarification of difficult-to-filter solutions, including serum and particulate-laden samples. It is often placed upstream of finer membranes to protect final filters and improve overall filtration efficiency.

This model features a 1.2 µm pore size, 47 mm diameter, and hydrophilic Versapor (acrylic copolymer) membrane on a nonwoven support. It is supplied in packs of 100 discs, making it suitable for routine laboratory workflows requiring consistent membrane performance.

Versapor membranes are known for being strong, flexible, and non-shedding in both wet and dry conditions. They also provide high flow rates at low differential pressures, helping laboratories process samples faster while maintaining reliable particle retention.

Yes. Versapor membrane discs are typically supplied non-sterile but can be sterilized by UV or gamma irradiation, or sanitized using appropriate laboratory procedures when required for the application.

The 47 mm diameter is compatible with standard filter holders, vacuum manifolds, and in-line filtration setups, making it a widely used format for environmental testing, sample preparation, and general laboratory filtration tasks.
