It’s Amazing works like a expensive one, i very happy to buy it

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.

Encontré el pedido, gracias; pero mi sugerencia es que tomen la foto y la envíen porque si se pierde uno está confiado que aún no llega porque ni en rastreo se vee. Gracias está bonito pero aún no lo he usado.

poor quality, it doesn't seem to have any type of vial or tube compatible with it. The 20mL tubes are just slightly too big- they end up wearing down at the bottoms along the inner walls of the centrifuge, and the tubes that it comes with don't fully hold lids on them and things end up spilling in the centrifuge and throwing it off balance I just started using it yesterday and the speed and time control knobs are already nonfunctional

La Máquina Centrífuga 800-1 es una excelente opción de nivel de entrada para cualquier laboratorio que necesite una herramienta básica y confiable para separaciones de baja velocidad. Es un equipo robusto y sencillo de usar, ideal para estudiantes, pequeños laboratorios clínicos o como respaldo. Si necesita una alta capacidad de procesamiento o velocidades de RCF muy elevadas, debería considerar un modelo superior.

Perfect for farm fecal tests. Quiet and easy to use.
