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.

Large, excellent toy with many squeakers!
Color: Blue, Color: Blue
This toy is excellent! I’m super happy with this purchase. My dog loves squeakers and there are so many in this toy, plus stuffing for her to rip out, and crinkle paper to take the sensory experience up another notch! It’s also more durable than many other plush-type dog toys, and is larger than expected which is a plus in my book. For size reference, both dogs are around 40lbs. I will be buying another as soon as this one is demolished!

Huge and fun. Good for two dogs to play with together.
Color: Yellow
This dog toy is great! And it's HUGE. Each tentacle crinkles, and the dogs love to play tug-of-war with it. It seems to be holding up well, too. It seemed a bit pricy for a dog toy, but it turns out it was worth it.

My dogs new favorite toy!
Color: Blue
His new favorite toy! My dog absolutely loves it!!! It’s much bigger than I thought it would be so my dog has to be careful when he’s running with it because he will trip on the legs of the octopus. The best part is there is a little squeaker in the bottom of each leg! Bonus!!! If your dog chews up stuffed animals, this will be no different. It is a stuffed animal. My baby just likes to carry it around and squeak it a 1000 times a day. Don’t mind my crazy voice in the video. That’s the voice I use when he’s excited about a toy. He greets me every day with his octopus.🥰

Fun while they lasted
Color: Green
I ordered two. One for each pup. Both my puppies loved this toy. The first one lasted less than a day with my pup who loves to do the death shake on everything. The second lasted two days with the other as she chews in the same spot. They loved the crinkle noise. However, I'm taking one star away due to not lasting long. Everything else was fine and they enjoyed them while they lasted. Note that most toys do not last long with my pups.

Puppy Loves this toy
Color: Tie Dye Blue
My puppy is a 7wk old Great Pyrenees & Lab mix. He loves this toy! Fun for tug of war and for cuddles. Definitely worth the money. It is durable enough for razor puppy teeth.
