WaterSep BioSeparations'​ mission is to develop and manufacture innovative crossflow hollow fiber products for the life science and biopharmaceutical industry that are robust, reliable and cost effective. Our single use Green Line cartridges and assemblies are gamma irradiated, humectant-free and ready to use. No pre-rinsing, cleaning or assembling needed. Autoclavable up to 5x our Steamer Line cartridges are designed for perfusion and aseptic applications. The low binding m-PES membrane in our reusable hollow fiber cartridges enables reliable crossflow, high product flux and easy cleaning. Offered in an extensive range of pore sizes and fiber diameters our HF cartridges, assemblies and compatible PC controlled console flow systems can provide your complete bioprocess separation solution. Manufactured and assembled in our ISO 9001:2015 certified facility our hollow fibers and cartridges can be easily certified for use in your process and be scaled from pilot to 1500L production batches without need for recertification or a change in performance. WaterSep hollow fiber cartridges afford significant savings in cost, time and facility space which greatly reduces CapEx and time to market. Our disruptive technology is being utilized by large and emerging BioPharma companies around the globe in upstream and downstream purification processes. Sample processes include perfusion and the cell harvesting and clarification of mammalian cell cultures, yeast and bacteria whole cell and lysates as well as the concentration and diafiltration of vaccines, mAbs, recombinant proteins, enzymes and peptides and oligomers.
