Overview

The Z446 universal centrifuge series offers the highest capacity of any benchtop Hermle-Benchmark model. With air-craft grade, premium alloy construction, the 4 x 750ml swing out rotor can withstand centrifugal forces upwards of 4,500 xg with full loads of up to 28 x 50ml or 68 x 15ml tubes.

Advanced microprocessor controls allow for instant rotor identification,which automatically converts the rotational speed to the relevant g-force (rcf), preventing the user from setting a speed above the capabilities of the installed rotor. In addition to retrieving saved programs, the easy to use front panel can adjust accel/decel rates, and change the end of run alarm tone. Rotor exchange is simple and requires less than one minute. An included rotor wrench can be used to loosen and install all rotors. As soon as the rotor is placed on the motor shaft, the identification process activates and the installed rotor code is displayed on the backlit LCD display.

🦴 The Ultimate Distraction: A Must-Have for Power Chewers!
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
Finding a chew toy that can withstand my 70-pound "House Hippo" (an expert-level destructor) for more than ten minutes felt impossible, until we discovered these stuffed shin bones. These treats are an absolute game-changer for long-lasting entertainment, durability, and distraction. Exceptional Durability and Value: The bone itself is thick, natural, and surprisingly sturdy. Unlike processed chews that crumble or get demolished instantly, these last for days of chewing. The value is tremendous because they provide two phases of entertainment: first, the intense effort of licking out the filling, and second, the satisfying work of chewing the bone itself afterward. Irresistible Appeal (Peanut Butter/Cheese Filling): The filling is the secret weapon! My dog goes absolutely wild for the flavor. The filling is firmly packed inside, which means he has to spend a significant amount of time actively working to get every last bit. This intense focus buys me hours of peace and quiet, which is invaluable. On top of that, they offer good nutrition! Less Mess, More Fun: I appreciate that these bones are relatively neat. They don't leave greasy residue all over the carpet like some marrow bones, and the durable exterior means minimal splintering (though, as with any bone, supervision is required). They satisfy my dog's natural chewing instinct while promoting dental health by scraping against his teeth as he works the chew. Final Verdict: If you have an aggressive chewer who needs a serious, long-lasting treat that is both entertaining and structurally sound, look no further. These stuffed bones deliver on their promise and are now a staple in our dog treat rotation!

Still Going Strong Months Later
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
These stuffed chew bones have been amazing for my dogs. Even months later, they’re still happily chewing on them, and that says a lot since they’re aggressive chewers. The bacon and cheese filling keeps them interested, and the bones themselves are durable enough to handle their chewing without falling apart. After all this time, the chews are still holding up and my dogs love them every time. They keep my dogs busy, help with dental care, and are definitely worth having on hand for large dogs who love to chew. Durable, tasty, and long-lasting—can’t ask for more.

Long lasting
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
These are the longest lasting bones I have ever purchased. But if you don't want a heavy bone that makes noise when dropped this is not for you. They go sliding across my floor as they are being tossed around and played with. But they love them and they have lasted for months. I am glad they are not as expensive as others. To many things are over priced. Dogs love them.

Arrived on time and as described
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
It is perfect for my 120 lb dog. He did give up after 6 hours of trying to get the “stuffing” out. The bone held up to his chewing. He loved it!

Be Very Cautious!
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
Splinters easily if you have an aggressive chewer! Although very tasty, within hours of a dog (lab/shepherd mix) I care for excitedly indulging in it, I was picking pieces he easily could have choked on (or worse). The large end of the bone splintered/cracked quicker than other bones he’s had which makes it very dangerous. Value for money is iffy due to that. Bone is a good price but not when it endangers the health of an animal. I gave it 3 stars because it had no smell, dog enjoyed the flavor, but definitely be cautious with this bone!
