- One-step sample concentration in a single tube for minimal sample handling and reduced sample loss.
- Patented dead-stop technology, which ensures that samples cannot be concentrated to dryness and enables direct concentrate recovery.
- Vertical polyethersulfone membrane minimizes membrane blockage and tolerates high flow rates.

The purification of biological therapeutics generally involves the use of cross flow filtration (tangential flow filtration) or normal flow filtration (dead ended filtration), combined with chromatographic separations. Cross flow filtration and normal flow filtration retain matter through size exclusion and are complementary to chromatography’s selectivity.
GE Healthcare provides several classes of filtration products. If you are not sure what class of product you need, please use our FilterBrain - Product Selection Tool. The product selection below features an array of membrane products and media that, together with GE Healthcare's systems, provide optimal membrane selection, ease of validation, and reliable, scalable platforms from the laboratory to production volumes.
