SUPER DEAL Electric Lab Laboratory Centrifuge Machine Low Speed 4000 RPM Capacity 20 ml x 6 Desktop Lab Medical Practice with Timer and Speed Control - 110v

Cool item. Use this for lab training. Works as intended and spins well.

This device is very similar to the centrifuges that we used in my high school chemistry lab. It's state of the art 1970's technology. It was old when I used it in the 1990's, but it worked.I did a series of about 40 runs on this machine to help clarify a particularly gooey herbal remedy that I make (contains several types of tree sap). I used either 1000 or 2000 rpm, with about a five minute timer. That was sufficient to get the liquid clear enough to filter. (I got over a liter through a 2 inch filter disc on a vacuum filter, and probably could have done more, but it would start to slow down at about that point.)I encountered no problems at all, however, if you have no experience with this type of thing, it could be very easy to damage.It's a fairly sensitive device as far as balance is concerned. I found that I needed to balance the weight of the tubes down to about +/- 0.1 grams. If your opposing pairs of tubes are off by more than that, it starts making a lot of noise, and if it's really loud, you have to turn it off pretty quickly to keep from destroying it. If you manage to balance the tubes exactly, at 2000 rpm, it makes only a very pleasant whirring noise. It's kind of tough to balance by eyeballing the liquid level in the tubes, but I was able to do it by using a pipette to transfer a few drops back and forth until it looked good.The included tubes say that they are good for 20 ml, but if you are going higher speed (e.g. 2000 rpm), I would suggest going only to about 19 ml. Otherwise, liquid starts coming out the sides of the tube and getting on the rotor. Getting different tubes with caps would solve that problem.

An indispensable tool for my work , it works very well , it was a great investment.

May work for others, but kinda lame for me.I guess I’m not as smart as the machine.

Excelente este equipo estoy muy contenta ! Llegó a buen tiempo y en perfectas condiciones. Sólo la probé donde la recibí, pero todavía no la he utilizado.

It's just what I need.

I bought this centrifuge in March in preparation for a project and I liked the price. I figured, it wouldn't be the greatest quality but should at least get the job done for the price.The noise level is extremely loud, which is ok since it's not running 24/7 or anything. My biggest concern is my 15ml tubes started melting at ~7 minutes in on 4k rpm. I opened the lid and smoke started coming out.Absolutely disappointed. I separated my project steps into different days in order to stay on track and now I have to wait for another product that I will be buying elsewhere. I don't want anyone to go through this so if you are on the fence, do not buy this product.

I've been doing my prp by myself
