Repligen"s innovative reservoirs are designed with a combination of configured ports, dip tubes and bottles to support Tangential Flow Filtration (TFF) applications. The dip tubes are cut and positioned to not only ensure that every last drop of solution is directed into the module, but also to prevent foam from forming in the solution. The reservoirs have been intentionally crafted to be seamlessly integrated into Repligen"s TFF pump systems-- such as the KR2i and the KMPi - for efficient and productive Tangential Flow Filtration processes.
