SOLA products provide unparalleled performance characteristics compared to conventional SPE, phospholipid removal and protein precipitation products. The proprietary manufacturing process involved in the production of SOLA products provides an SPE product which eliminates issues normally associated with conventional loose packed SPE products, by combining the polyethelyene frit material and media components into a uniform sorbent bed, removing the need for frits. The animation below illustrates how SOLA eliminates common issues associated with conventional loose-packed SPE products.
