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, 68 x 15ml tubes, and up to 20 x microplates.
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.

Good Product
Package Size Name: XXL, Size: 150 sheet (Pack of 12)
These would compare to Sparkle brand. Every sheet was very absorbant. I tried these because they were cheaper. I didn't know what to expect. They were just plain white, looked clean while sitting upright just plain. They come with select a size. I thought they were great!

Thin and cheap

Very thin, cheap and just not what I was expecting based on the great reviews and paid a little more too. Meh.

MY DOG LOVES IT
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
MY CHIHUAHUA WON'T GET OUT OF THIS BED! she loves it! from the first moment we brought it in and put it on the floor. she gently scratches at the sides and cuddles in with her blankey and likes she's not there. ohhh... great value for the price! nice size, big enough for both of my chihuahuas to lay in comfortably. soft, but very sturdy sides, the bottom is fluffy, padded very well. the outside bottom, there is a non stick covering so the bed doesn't scootch around on tile floor, it stays put.

It's lasted
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
I've had this bed for 5 years and it is still in great shape. Washes up in the washing machine just fine. My littlest dog absolutely loves it and is lost when our other bigger dog steals it. She barely fits in it but she loves it too. Ha! Good quality at a good price. Couldn't ask for more.

My Puppy Loves It.
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
I didn't know what to expect when I saw this advertised, but some reviews said that their puppy had chewed on it and it was still holding up with no holes. So, I decided to get it and see for myself. I have to say that my puppy loves it and chews on it and it is holding up very well. No holes yet and I suspect after all her chewing and no holes, there won't be any. Nice size for a 25 pound dog and smaller. Well built and nice looking bed. It has enough padding to make it soft for my puppy. I got it big enough, so she can grow into it, too. Well satisfied and I do recommend it.
