BJP Clinical Concentrators

0.5 to 20 ml starting volume

BJP concentrators use absorbent pads mounted behind the ultrafiltration membranes to remove sample solvents and small molecules. The retained proteins are concentrated in the bottom of the sealed sample chamber without the need for centrifuges or other equipment. Integrated dead-stops ensure the highest concentration factors while avoiding sample loss through concentration to dryness. These devices are intended for in vitro diagnostic (IVD) applications. BJP concentrators are an excellent Minicon® B15 Concentrator replacement
