Increase Laboratory Efficiency with
Ready-To-Use Disposable Filter Funnels
- Certified. Each lot is certified for microbiological analysis to provide added assurance of reliable results.
- Easy to use. Unique squeeze separation of cylinder from base allows easy access to membrane.
- Individually bagged, disposable filter units prevent cross-contamination of samples.
- Available in 300 mL capacity to process larger samples.
- Allows easy and accurate sample measurement. The 100 mL funnels are marked in 10 mL increments. The 100 mL increment is marked completely around the funnel for higher visibility. The 300 mL funnel is marked in 50 mL increments.
- Saves time. Disposable design eliminates the cleaning and sterilization required with reusable funnels.
- Ready to use. Pre-assembled and gamma-irradiated to eliminate the potential for toxic extractables associated with EtO sterilization.
- Variety of options. Choose from GN-6 Metricel® membrane in 0.45 μm pore size, Supor® membrane with 0.2 or 0.45 μm pore size, or Metricel Black membrane with 0.45 or 0.8 μm pore size.
- Easily remove the membrane for culturing on agar or broth medium

- Test any aqueous solution for microbial contamination using the principles of the Membrane Filter (MF) Technique.
- Ideal for quality control analysis of aqueous fluids used in pharmaceutical production. Individually labeled for lot traceability.
- Convenient for last-minute samples at the end of the day or work week. Maintain a supply of MicroFunnel filter funnels in case the autoclave breaks down and reusable hardware cannot be sterilized.
- The 300 mL funnel is ideal for processing larger samples without the "pour and wait" of smaller funnels. Processing larger samples can improve sensitivity and confidence in the results.
- Test for a variety of bacterial contaminants, such as Total Coliforms or Pseudomonas species, by choosing between the 0.45 and 0.2 μm pore sizes.
- MicroFunnel filter funnel with Metricel Black membrane provides a better contrast for counting yeast and other light-colored colonies.

Procedures for MicroFunnel™ LP Filter Funnel (with Petri Dish Lid Kit)
- Dispense the contents of an ampoule of culture medium onto the absorbent pad in the Petri dish lid kit, supplied only with MicroFunnel LP, PN 4810.
- With Petri dish lid kit removed, perform filtration then access membrane by gently squeezing near the top of the funnel cylinder.
- Remove the membrane filter from the base with forceps.
- Place the membrane filter onto the broth-soaked absorbent pad in the Petri dish lid kit.
- Cover, invert, and incubate.
