Autofil PP bottle-top filters for solvent filtration are a revolutionary new way to purify solvents for analytical applications to obtain sterilized or purified extracts. The AutoFil PP is the world’s first single-piece polypropylene funnel, designed to withstand harsh solvents that would normally degrade traditional bottle-top filter assemblies. All active components are FDA-grade which makes Autofil PP perfect for the extraction of compounds used in the food and drug industry. Autofil PP is designed to conveniently fit on top of most laboratory bottles with a GL45 thread and works great with the AutoFil Ring Cradle. Autofil PP is available in three membrane types: PES, Nylon, and PTFE. Pore sizes include both 0.2μm and 0.45μm options. Available in two funnel sizes of 500mL and 1000mL.
