Autofil 250ml is available as either a complete system or as a funnel only bottle-top vacuum filter. The patented next generation product comes with 3 different asymmetric PES membrane pore sizes ( .1μm, 0.2μm, or 0.45μm). Our membrane is low protein binding and surfactant-free. The Autofil system is designed for sterilization or clarification of aqueous laboratory fluids. The filters are sterilized in the USA. An industry first, Foxx Life Sciences sells a stable, low-profile, patented optional pedestal base or a low cost ring-stand cradle. Each holder provides a stationary vacuum hose connection that makes set-up and use quick and efficient while preventing spills and tissue culture hood contamination. These holders also allow for hands-free operation of the filter unit. Foxx Life Sciences' Autofil is manufactured in ISO 13485 clean room in NA.
