Autofil Bottle Top Filters

The Autofil laboratory filtration system is a disposable, sterile, vacuum operated bottle-top filter system used for the preparation of buffers, tissue culture media, microbiological media and other biological fluids.

This hands-free filtration system works in conjunction with the Quick-Connect Pedestal or Cradle Ring which provides on/off vacuum flow control.

Autofil bottle top filters are available as a complete system or just as the bottle-top filter itself. Both options have an upper filter funnel with dust cap that contains a 0.1μm (mycoplasma filtering grade), 0.2μm (sterilization grade), or 0.45μm (clarification grade) asymmetric PES membrane. The membrane is low protein binding and surfactant free.
