PALL 4817 MicroFunnel™ Plus Filter Funnel with Metricel® Black Membrane, 300 mL, 0.45 µm, Black, Gridded, Sterile, Individually Bagged (20/pkg)

MicroFunnel filter funnels provide an easy squeeze separation of the funnel from the base, preventing membrane disruption and eliminating any twisting motions that can tear membranes or result in RSI. The base of the funnel can easily convert to a Petri dish for culturing using the provided funnel lid. Alternatively, the membrane can be easily removed for placing on a separate agar dish.

MicroFunnel filter funnel units are available with a range of microbiology membrane filters. Pall’s Metricel Black PES membrane is an excellent choice for the isolation and enumeration of yeast and mold colonies, the dark background provides a contrast for counting opaque colonies in microbiology labs.

Certified: Each lot is certified for microbial analysis to provide added assurance and reliable results with self-serve certificates and other regulatory information available online.
Single-use: Prevent cross-contamination with individually bagged, disposable units that are gamma-irradiated, and avoid the need to clean, package and sterilize.
Easy to Use: Unique squeeze separation of cylinder from base allows easy access to membrane for simple removal for culturing on agar or broth.
Accurate sample measurement. The 300 mL funnel is marked in 50 mL increments, and as with all our funnels, accuracy is confirmed to within +/-2% at the max volume.
Confidence: With gamma irradiation, there is no potential toxic extractables sometimes present with EtO sterilization and molded-in measurements on the inside of the funnel ensure all liquid is filtered and reduces the possibility for false negatives.
Convenient: Ideal for last-minute samples at the end of a day or work week. Maintain a supply of MicroFunnel filter funnels in case the autoclave breaks down and reusable hardware cannot be sterilized.
