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. These devices offer high recoveries, typically > 90%.

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.

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. Membrane inserts feature color coding for the easy identification of MWCO.

Membrane inserts are designed to be used inside reusable Jumbosep units. Jumbosep starter kits including four holders, cups, caps can be purchased separately.

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.

Durable Chew Toy with a Fun Design
Size: Medium, Style: Bow Tie, Product Packaging: Standard Packaging
The KONG CoreStrength Bow Tie Bone is a playful and sturdy chew toy made to keep dogs busy. Its unique bow tie bone shape makes it easy for dogs to grab and carry, while the reinforced core is built to handle strong chewing. The textured surface not only adds interest but also helps clean teeth and gums during play. It’s tough enough for moderate to heavy chewers and works well for fetch, solo chewing, or tug games. While no toy is completely indestructible, this one holds up longer than many softer toys and gives dogs plenty of chewing satisfaction. Some very aggressive chewers may eventually wear it down, but most dogs will get a lot of use out of it. Pros: The reinforced core makes it more durable than average toys, the textured design supports dental health, and the shape adds variety and fun. Cons: Very heavy chewers may still break it down over time, the toy is fairly heavy for small breeds, and it isn’t designed to bounce or fly like other KONG toys. A strong and engaging chew toy that combines durability with a fun shape. It’s a smart choice for dogs who love to chew and play while also supporting healthier teeth and gums.

Best chew toy for GSD’s
Size: Medium, Style: Bone, Product Packaging: Standard Packaging, Size: Medium, Style: Bone, Product Packaging: Standard Packaging
One of my dogs has chewed through most chew toys for aggressive chewers with ease. This toy not only is still in one piece but still her favorite toy. We’ve gotten her many Kong toys and this one has definitely lasted the longest. She’s been chomping on it for about 2 years now and looks mostly whole.

Perfect for light/moderate chewers
Size: Extra Small, Color: Blue, Size: Extra Small, Color: Blue
My dog wouldn’t stop biting on the toddlers plastic dinosaur toys, so I got him this because it’s similar to plastic. But not hard enough to where it could damage his gums, also not soft enough to break apart. It’s perfect and he’s very happy with it. My dog is 6 LB toy poodle for reference, I would say this is suitable for small dogs. I saw reviews saying that their dog absolutely destroyed it immediately, but then in the review pictures their dogs were baby bulldogs/german shepards! This isn’t meant for breeds like that, but if you have a smaller dog with smaller teeth then this is ideal.
