Bottle Top Filter Unit

The Autofil™ laboratory filtration system is a disposable, sterile, vacuum operated system used for the preparation of buffers, TC media, microbiology media and other general filtration requirements.

The Autofil™ filtration system is available with either a 0.22um PES membrane (Sterilization grade) or 0.45um PES membrane (clarification grade). The membrane is low protein binding and surfactant-free. The system includes a graduated funnel assembly with membrane, and attached screw top reservoir bottle with bottle cap. Additional bottles are available as accessories.

Also available is a stable, low-profile pedestal base or a low cost ring-stand cradle. Both provide 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. After removing the filter devices from their packaging, the operator places the unit onto the cradle engaging the vacuum port, removes the dust cover, and pours liquid into the secured filter funnel. No holding of the base during operation is required. Both cradle options have an integrated vacuum on/off switch.
