Autofil® PP Bottle Top Filters

Foxx Life Sciences offers a revolutionary technique of solvent purification in analytical applications through its Autofil® PP bottle-top filters. The world's first single piece polypropylene funnel developed by Foxx to withstand harsh solvents that typically degrade regular bottle-top filters.

The Autofil® Vacuum Filtration System is a disposable, sterile, vacuum operated unit used for the preparation of buffers, tissue culture media, microbiological media, and other biological fluids. Designed for purposes of fine sterilization or clarification of aqueous laboratory fluids, all active components are FDA-grade which makes Autofil® PP perfect for the extraction of compounds used in the food and drug industry.

Foxx Autofil® PP is designed to conveniently fit on top of most laboratory bottles with a GL45 thread.

The filters are Gamma sterilized in the USA, Class VI materials.
