These units can support vacuum filtration of samples up to 250 mL. They were designed for research purposes and the filtration of small volumes.Polyethersulfone MembraneSartolab® RF 250 PES Vacuum Filtration Units include a unique polyethersulfone membrane. This membrane is the optimal choice for your filtration needs, combining low protein binding properties and the highest flow rates. With a pore size of 0.22 µm, the filtration units can meet the demands for multiple applications, including sterile filtration of cell culture, media, buffers and reagents.State of the Art EngineeringSartolab® RF 250 PES Vacuum Filtration Units were designed to optimize your user experience in vacuum filtration. Sartolab® RF 250 PES Vacuum Filtration Units include a vacuum tube connector for stand-alone filtration (these units can also be used with the Sartolab® Multistation). Further, a screw cap has been included to store the filtrate. The screw caps of the bottles are delivered extra packed, individually wrapped to maintain sterility. Notably, the 45 mm neck thread of the Sartolab® units ensures a vacuum-tight seal to bottles with this standard thread.Minimized Contamination RiskSartolab® RF 250 PES Vacuum Filtration Units are ready-to-use units, minimizing the risk of contamination. There is no further need for liquid transfer for storage as the unit.
