Jumbosep centrifugal devices provide the rapid and convenient concentration, diafiltration, and fractionation of biological samples. These uniquely designed, large volume, spin filtration products can accommodate samples up to 60 mL and concentrate a 60 mL sample to 5 mL in typically 30 minutes.

Concentrates 60 mL sample volumes to 5 mL in 30 minutes
Provides high recoveries, typically > 90%
Low protein-binding Omega membrane and polysulfone housing minimize losses due to non-specific binding
Versatile Omega membrane is available in a variety of MWCOs, color coded for easy identification
Built-in deadstop prevents spinning to dryness
Unique sealing mechanism prevents retentate leakage and filtrate contamination
Jumbosep centrifugal devices can be used across a range of ultrafiltration applications. They are ideal for buffer exchange or salt removal of chromatography eluates and gradient fractions. They may also be used for virus concentration or removal; concentration or desalting of enzymes, antibodies, growth factors, lymphokines, DNA, and RNA samples; and separation of antibodies and other biomolecules from cell culture.

The product features a sample reservoir and filtrate receiver, both manufactured from low protein binding and chemically resistant polysulfone material. The sample reservoir and filtrate receiver can be sanitized and reused. An insert release concentrator receiver unit is supplied to ensure the efficient recovery of concentrated samples.

Jumbosep Omega membrane inserts are available in a range of MWCOs. The Omega membrane is manufactured from low protein binding modified polyethersulfone, minimizing the possibility of sample losses due to non-specific binding. These devices offer high recoveries, typically > 90%.

Jumbosep units should be used in a swinging-bucket rotor that accepts standard 250 mL bottles. Users should spin their samples at 1,000 to 3,000 x g, typically for 15 to 40 minutes, to achieve the desired retentate volume. A built-in deadstop prevents from spinning the sample to dryness.

Jumbosep starter kit including four holders, cups, caps, and membrane inserts of chosen MWCO is available for purchase. Packs of replacement Jumbosep membrane inserts may be purchased separately. Membrane inserts feature color coding for the easy identification of MWCO.

Great quality and made in the USA!
Pattern Name: Cow Chew Toy Set
I'm very happy with these toys. I can't stand these other toys that break easily and are from other countries that just don't have the same standards we do.

Great pack of toys for your fur-baby
Pattern Name: Cow Chew Toy Set
Our sweet Ziggy loves these toys. A couple he doesn’t pay much attention to, as he has favorites but there is a good variety and he’s enjoying all. The blue rubber toy with ball shapes in end you must watch them with, even with baby teeth he was able to chew ridges enough to get tiny bits of plastic/rubber off in about 10 minutes. He still plays with it outside. His favorite is the nubby blue/white bone, the rope/ring and snuggly plush. Good value!

Far Exceeded Expectations
Pattern Name: Cow Chew Toy Set
This was the first online purchase of dog toys that I made after we got our puppy. Purchase was made in August 2023. Currently February 2024. Honestly, they were a little oversized for her at the beginning, but she still played with the stuffed cow (it was kind of her woobie) and some of the others. Seven months in, here are her "reviews": Round bone thing: Only clunker for our pup. She never took to that. Cow plush squeaky: Loves it. Easy squeaker so a small puppy can still make it squeak, which they love because they think they're killing it. Flat bone: Excellent for the devoted chewer. This has withstood many hours of gnawing with little evidence of wear. I do inspect it regularly because the hard plastic edging could be problematic if it starts to degrade. But it's holding up so far. Blue double knot rope toy: This was one of her first chewers. She still loves it, though it does show wear because she is chewing off the tassles over time. Totally worth it. Rubber ball with bell: She likes this, especially if someone throws it for her. From an owner standpoint, it gets slimy with saliva pretty quick, so I'm less enamored of it than she is. She hasn't used it as a chewer, though I'm sure some do. We leave it in her crate at night and that's how we know she's awake in the morning, because the bell tinkling as she rolls it around in the crate is a giveaway. The rope ring thing is her A#1 very favorite thing, not just in this pack but among the wide variety of toys she has. She chews on it all the time and I'm back to order a new set of toys just to be sure we have one ready for the demise of the first. She loves to have it thrown, but she'll also just sit and chew on it. She also loves to do what my son calls "the spin cycle," in which she holds the rope in her mouth and throws the ring end all around as she spins. It's entertaining to watch. My aunt would have said, "Oh, look, she's playing with herself." To which my cousin would have replied, "No, Mom. Not WITH herself, BY herself!!!" Remembering which just entertains me all the more. Now, a Boy Scout or sailor with knowledge of knots could re-string the one I have with new rope, I'm sure. And the next time I visit my dad, I'll ask hime to do just that. But for most people that's a bridge too far, so this company would be wise to sell just the rope pull toy. I haven't found a similar design on Amazon. We have found this set to be a great value and highly recommend it.

AMAZING Toys for Teething and Mouthy Puppy
Pattern Name: Cow Chew Toy Set, Pattern Name: Cow Chew Toy Set
These toys have been a lifesaver for us with our 14 week old, 7.7 pound, King Charles Cavalier, Oliver. He is teething with his razor-sharp teeth and needs things to chew on that are not our hands, arms, clothes, chairs. He loves these toys! All of them have been enjoyed by him, but the Tug Ring is, by far, the most helpful with his teething. It is super durable and the perfect size for him. His runs around like a crazy-dog with it and then can settle himself chewing on it. The stuffed toy has been a comfort to him while sleeping and he also loves to sit and gnaw on the teething bone or run with the rope. The ball is a little large for him, but he still enjoys chasing it and scraping his teeth on it. We've had the toys a week and they have helped so much to provide appropriate chew things and distract him from inappropriate ones! The only other toy we have purchased is a smaller ball for Oliver to chase. These toys provide all we need!!!! Highly recommend!!!
