MicroFunnel™ ST Disposable Filter Funnels

Convenient and Economical Choice
for Sterility Testing Within Isolators

• MicroFunnel ST filter funnels offer an alternative to costly closed-system sterility testing when using an isolator or containment suite
• 0.45 μm GN-6 Metricel® membrane or low binding Supor® membrane provides a choice for sterility testing applications in the pharmaceutical industry
• Supor membrane is ideal for testing antibiotic solutions
• Double bagged packaging ensures easy transfer through airlock
• Simple squeeze separation design makes membrane retrieval easy
• Meets requirements of U.S., Japan, and European Pharmacopeias for sterility testing

• Test any aqueous solution for microbial contamination using MicroFunnel ST disposable filter funnels and the principles of the Membrane Filter (MF) Technique
• Ideal for quality control analysis of aqueous fluids used in pharmaceutical production
• Quality control testing of final product for release
