PALL 4818 MicroFunnel™ Filter Funnel with Supor® Membrane, 300 mL, 0.2 µm, White, 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 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 Product, But Non-Existent Seller Support
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
The Good: Well Designed: Sturdy and aesthetically pleasing. Effective: Perfectly obstructs the afternoon sun glare from my monitor screens. Moderate Assembly: Straightforward and easy for the most part. The Bad: Defective Part: One crossbar end was missing threads, preventing the assembly of the sixth panel. Zero Communication: I emailed the seller as instructed and waited 8 days with no acknowledgment. Return Logistics: Amazon offered a return, but the box is heavy, and disassembly/repackaging would be a major task. Final Verdict I really like this product, but I’m deducting two stars for a total lack of customer service. I’ve decided to buy tools and fix it myself rather than deal with a heavy return. I hope the seller sees this and reaches out. The lesson learned is to check every part of a product before assembly.

Clean Look, Sturdy — can’t ask for more!
Size: 6 Panel-119"W, Color: Grey, Size: 6 Panel-119"W, Color: Grey
Really like how it folds so I can create kind of a doorway with two of these. Pretty easy to assemble and has an uncluttered clean look due to the smooth fabric and nice color. Oh and it’s sturdy enough for pets.

Pretty good, especially for this price point.
Color: Beige, Size: 21.5"- 1 Panel
This is merely a piece of cloth stretched between the frame borders, but it works perfectly. It arrived quickly, all parts present and in good condition. I didn't put the castors on, as it will be more or less always in one position. I simply attached some felt sliders on the bottom to prevent scratching the floor and to allow clearance for the center screw (which is not flush fit). Overall, a reasonable deal for the price point.
