MicroFunnel™ Disposable Filter Funnels

Save time with disposable units by eliminating the cleaning and sterilization required with reusable funnels.

• Disposable
• Ideal for aqueous solutions
• Squeeze separation

MicroFunnel™ filter funnels are ideal for testing any aqueous solution for microbial contamination using the principles of Membrane Filter (MF) technique

The unique squeeze separation makes membrane retrieval easy. Choose from 0.45 µm GN-6 Metricel® (mixed cellulose ester) membrane used for most applications, 0.2 and 0.45 µm Supor® (polyethersulfone) membrane to minimize binding of inhibitory substances, or Metricel® Black (modified polyethersulfone) membrane for better contrast with light colored colonies. Available in 100 and 300 ml capacity. Graduations marked on outside of cylinder for better visibility and easy measurement. Gamma irradiated. Gamma irradiation dose is 15 to 30 kGy.

Applications include quality control analysis in pharmaceutical production, analyzing process water for industrial applications, and testing drinking water or wastewater for contamination.
