Original Press Release:

Filtering HPLC Solutions or Other Solvent-Based Liquids for the Lab?

Sterlitech is proud to launch a new product based on the successes of the Autofil bottle-top disposable filter funnel, now in a solvent-resistant version.

The Autofil PP bottle-top filters are a revolutionary new way to purify solvents for analytical applications or purify buffers and extracts. These new devices are the world's first single-piece polypropylene funnel, designed to withstand harsh solvents that would normally degrade traditional polystyrene bottle-top filter assemblies. All active components are FDA-grade, which makes Autofil PP perfect for extracting 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 seamlessly with the same no-spill cradle system that made the original Autofil funnels such a success. The Autofil PP funnels are not pre-sterilized owing to their predominant use within analytical chemistry, but this service can be quoted separate if needed.

The Autofil PP funnels are available in three membrane types: PES, Nylon, and PTFE. The PES provides an ideal application solution for the botanical extraction/cannabis market when filtering ethanol-based extracts. The Nylon and PTFE versions are perfectly suited for filtering HPLC solvents containing acetonitrile, DMF, methanol, and more. Pore sizes include both 0.2μm and 0.45μm options in 500mL and 1000mL funnel capacities.
