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.

Definitely a good surprise
Size: 12.5, Color: A Black
Absolutely the most comfortable shoes I have ever had. Extremely lightweight true fit. They are very breathable. They are not a running sneaker. They seem to be very durable as I wore them everyday of vacation while walking around Las Vegas. I would definitely buy them again. Very good buy for the price

Didn't fit my narrow feet, but still excellent shoes at a great low price
Size: 11, Color: A Black
These are some of the lightest shoes I've ever seen, but the build quality appears to be excellent. They're tongue-less, like slip-ons, but unlike some, you can adjust the tightness with the laces. The body of the shoe is a mesh-like fabric, which allows good breathability and overall comfort, and the soles are a molded rubbery material with nice treads for grip. I've been wearing a name-brand shoe made very similarly for a couple of years, and these are a very good likeness of them, at a much lower price. I like them because of the light weight and the fabric, which make them feel almost like you're barefoot. Unfortunately for me, I have narrow feet, and these fit more like a D width shoe, with more room in the toe box than I can handle. I'm returning them for that reason. For people with "normal" feet, these make really nice, stylish and comfortable shoes. I don't know how well they would hold up to sports or running, but for walking and day-to-day wear, they're great. I suppose I could grade them down because they don't fit my feet, but I find lots of shoes don't, and many makers use D width as the default for men's shoes. So I'm still rating them as 5 stars.

In a pinch they're worth it.
Size: 12, Color: D Grey
I got the dark gray color. They came exactly as pictured and are decently comfortable but as far as packaging it's very poor. They come in a small plastic bag all squished and deformed so you have to wear them a few times before they take shape again. For the price it's a great buy for some generic work shoes or something, the bottom tread doesn't last long at all though if you're expecting them to last a long time as it will be gone in a week or two if you wear them frequently. Buy them if you don't feel like spending a lot of money on shoes but want a new pair cheap.

Ladies, don't be afraid. Buy 'em. Trust me
Size: 9.5, Color: A Black
My elderly mother adores these. She had to have breathable awesome shoes for post-surgery and these fit the bill (and her feet!) So i got some for me. Whoa. Comfort! And I love the slip-on ease, b/c sometimes I just need to go, go, and go some more. Love them in black, haven't had long enough for durability, but helpful for my mom in her physical therapy and they're holding up to the worst she can do to them.

Good overall shoe, great for basic needs
Size: 12, Color: A Black
These are nice shoes. I put $40 arch support insoles in mine, so I like them even more, but they were fairly comfortable even without. They fit well, though slightly large, and seem to hold up well. No real complaints, though made a bit cheaply.
