Valpha® Syringe Filter for Virus Removal Filtration

Valpha® virus removal filters use membrane filtration technology to remove virus particles based on size exclusion. It uses an innovative high-performance polymer membrane to trap the virus on the membrane surface and in the membrane pores. Valpha® family virus removal filters provide you two choices of membrane: Valpha RC (Regenerated Cellulose) and Valpha PES (Modified PolyEtherSulfone).

Product Description

Product Description

Valpha® RC HP uses regenerated cellulose membrane. Cellulose is a high hydrophilic material and is widely used as a basic polymer in the preparation of filtration membranes. The natural hydrophilic properties of cellulose maximize protein recovery by reducing protein adsorption. In addition, cellulose membrane can maintain high LRV value and filtration flow rate in long time filtration. Moreover, it has broad applicability and is suitable for virus removal process of multiple biological products.
Valpha® PES uses modified polyethersulfone material, and its unique asymmetric structure provides more possibilities for high process flux. At the same time, the unique modification and membrane preparation process provides Valpha PES membrane very low protein adsorption and high flow rate. It really achieves the target of high flux, high load and high flow rate.It is truly characterized by high throughput, high loading and high retention.
