NEWTRY 20mlX12 Electric Centrifuge Machine Desktop Lab Benchtop Centrifuges with Timer and Speed Control 4000rpm 80-2 (110V US Plug)

There is nothing good about this I was able to use the timer only twice before it Despite the fact that it rattles and is so loud, I cannot even speak among the noise. But they refuse to There's no point in it!.

Taking a video would have helped me explain it better because it would be self-explanatory. The centrifuge I worked with yesterday occupied several hours of my day. The only instruction I had was to turn the dial for speed and time. But apart from that it was fairly straightforward. . . . and a bit about how it is suitable for medical/ scientific use (DO NOT 2) I made sure the contents were balanced well. Twelve 15ml vials each with a capacity of 10 ml each were used. This project is uncertain as to whether it can be run with 3 or 4 (balanced), if it needs to be balanced, and if it can be run with one, two, or ten. Since it has to be balanced, I started with the assumption that it is. As long as I ran the rotor at 1,000 or 2,000 rpm, it was okay. The vibration started violently shaking when I turned the volume up to 3 (actually, to 2500). It shook all over the place at 4,000 rpm, by which I meant it flailed all over the place and couldn't be focused Compared to the counter height, the bowl is 6 inches tall, and would have fallen off if I had not grabbed When my husband came into my room and started it (which is how I discovered it started shaking at a lower rpm), I figured out what was wrong. According to him, you need to have an isolation table in order to make use of this. I realized that it was on a sturdy table (in fact, it is just about all of the instructions). In my experience, I have used a mixer with 800 watts and two with 200 watts. The counter could hold 5 horse power blenders with no problem at all. It wasn't the counter that was the problem. In this case, it was very clearly the centrifuge, which must not be driven over 2000 rpm without shaking like it's about to The second reason is because I shut it off when it began vibrating the other day. Shaking violently) spoiled the contents, which I had to throw away. Next, I wanted to see what happens if I turn the speed up to 3,000 or 4,000. Within a few seconds, it began to leap forward, backward, and sideways, moving 4-inches per second Across the counter it is 6 inches wide. I would have been there in less than 30 seconds if it had fallen. It would be great if you could film it for me, but I really don't want to spend the time precisely filling a dozen test tubes to maintain the centrifuge's balance, just to show that it remains unstable even when it is running.

My only complaint about it is that the timer dial broke after just one use, so I can't tell how long it's running for.
