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 Supor polyethersulfone membrane is the ideal choice for microbiology labs requiring isolation and enumeration of organisms stunted in size from exposure to harsh conditions. Allowing for the easy isolation and enumeration of Pseudomonas species, especially stressed organisms, found in process water and other fluid samples (like those analized in the electronics and pharmaceutical industries).

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.

Great shelves!
Size: 24x5.8, Color: Black, Size: 24x5.8, Color: Black
I love these shelves (I purchased 6 shelves total). The size I got was perfect, looks phenomenal, & quality is great too! Only negative thing I’d say is that it could be difficult for some people to set up as it needs to be leveled, & can be hard to align with other things since the part that attaches to the wall is separate from the shelf (due to its floating design) but once it’s up, it looks great. Definitely good value for money with its quality. I have them to hold up decorations/toys, & you think some of my shelves have about 5lbs of stuff on it & I’ve had no issues, so functionality is good.
