  • Exhibit low protein binding and excellent flow rates
Nalgene Filter Units provide a complete vacuum filtration system designed for the filtration of cell culture media, biological fluids, and other aqueous solutions. Each filter unit consists of polystyrene housing with a welded filter membrane mounted to a support plate in the upper structure. Side arms with quick-disconnect tubing adapters simplify vacuum line attachment. The upper structures are easily separated from their receivers and a sterile, leakproof closure is included for filtrate storage.
