Electric Centrifuge Machine for Laboratory Medical Practice,Timer(0-60min) and Speed(0-4000rpm) Control Capacity 20 ml x 6 Tubes,110V Low Speed Portable Desktop Benchtop Centrifuge

I got this babe to extract alkaloids of interest from dried cactus incense chips. Whoa, talk about manifest increase in processing efficiency!! Xylene moiety separates from polar in 2.5 min at 2000 rpm, increasing operational yield by over 100%! HIGHLY RECOMMENDED. You just got to be patient or go for a bigger horse if you have a lot to process. A quart of cactus glop is 1000 ml, so use separator funnel and pipette as much as possible., 'cause otherwise it will take 7 times 2.5 min loads to process a whole quart. But the main point is, this mother (second siri dictionary definition, please) kept horsing through all those mother aloquits, Maybe 50 merry go rounds during a day or so, and everyone perfect! The MAIN PROBLEM is that they sent an extra speed control knob, and I wondered, when i received it and all along with a well packed centrifuge except for again WTF why are the tube caps stuck between the rotor and the wall, because THEY WEREN'T WELL SECURED DURING SHIPPING but with deftly administered forceps the caps were successfully retrieved, and this mother ran like a champ!! The speed control knob falls off easily, BTW, but it is easy to figure out. HIGHLY RECOMMENDED for the price. I mean really, $65 for a 6x20ml! I've seen the same price for 6x5ml, which is fine i mean if you need to count platelets to put bread on the table or whatever, but, for $65 I increased my retrieval in an acid/base extraction with xylene of alkaloids of interest by nearly 275%! Preliminary figures indicate total alkaloids of 2% by weight from dry incense input material. Centrifuge no doubt tripled productive yield.

I'm using this to make PRF that I inject and microneedle with. This little machine is TOO easy to use, very high quality and I really like it. I was nervous because the price was so low but I was pleasantly surpised. I've used it three times now and it works just as well as the first time I turned it on. It feels very sturdy, there's no loose parts and it's not very heavy at all. The suction is good. It might move around in a circle but it only moves on a zero turn so it's not a problem at all. It won't end up in the floor or anything. I thought it was cute how it slowly did a zero turn, lol, girls 😂 I'd say if you slightly slight wet the suction cups it wouldn't turn at all. And it only turns at high speeds. Very good buy.

so far so good, this product works perfectly as described. Spin fast but not noisy, it comes with 6*20ml tubes, speed knob and screwdriver, and it really gets the job done! My coworker loves it a lot, and about to purchase another one. Generally saying, this is an excellent product at a low cost, save space, plus very easy to use! I am satisfied with this purchase (I wish I've found this one earlier!!!)

I actually just finished using it for the 4th time,so far has worked really good. Problem today while spining on 3000rpm, started hearing a different noise,the blood product was good as expected,but I lift centrifuge one auction leg came off, the noise I heard is the loose nut inside the unit. So now I'm going to see if can get replaced.

Suction power??? First, let me say, you won't find a better centrifuge for anywhere near this price. I just received mine and found it to be quite satisfactory. The unit runs quiet, with minimal vibration, with or without the tubes, even at full speed. The extra speed knob is a little puzzling as is the provided nut-driver that doesn't fit anything on the centrifuge. I had assumed it was for removing the rotor but it is way too small for that. Also, the tubes have no caps. Initial inspection looks good. We'll see how long it lasts.

My order was missing instructions, tubes and the other bonus parts, Amazon gave me a partial refund for that. So I had to buy some tubes on Amazon but all 20ml tubes appear to be the same. When I fired up the centrifuge there was a rattling sound at low speed, I found pulling the power cord out solved that, guess there was more inside the housing than needed to be. The next issue is that at certain speeds and/or after spinning for a few minutes, the tubes will just barely hit the screw supports within the housing. It sounds a bit like static electricity sparking when this starts to happen. I have confirmed tubes were identical in weight down to 100th of a gram and tried re-seating the tubes when this happens but it doesn't help. Adding a small o-ring to raise each tube slightly seems to have fixed that. Oh and for some reason my unit says Kenley and not Rovsun even though the sticker and barcode on the box say Rovsun. I did a search and found that there was a near identical listing which was removed from Amazon recently but you can still read many of the reviews via Google's cache. At the time it had 3.4 stars from 19 reviewers and was the #1 top seller. Overall for the price ($62 when I got it), it's a good deal and I'll likely buy another if this one breaks.

Already quit working for sure don’t buy sent me a new one no problem and it works’

Product is fine but I don’t need it! I can separate the blood from plasma with time I sent 3 noted to seller and never responded! I should be able to return a new product and I’m trying to get amazon to help me out
