These vacuum bottle top filter systems provide a cost effective and efficient solution for sterilizing and clarifying aqueous biological media. Featuring a 0.22 μm PES (polyethersulfone) membrane, they offer high flow rates, low protein binding, and minimal chemical extractables—ideal for general purpose laboratory filtration where extreme chemical resistance is not required. • High flow rates and throughput • Low protein adsorption and low extractables • 0.22 μm PES membrane for reliable sterilization • Sterile, non pyrogenic, DNase/RNase free • E beam sterilized, SAL = 10⁻⁶ • Individually packaged in sterile bags • Endotoxin free and pyrogen free
