NORJIN Electric Lab Laboratory Centrifuge Machine with Speed Control and Timer, Lab Benchtop Centrifuges AC 110V Capacity 6 x 20ml Max 4000 RPM

Calidad extrema

Suctions to the floor/countertop well and stays in place. I've used it half a dozen times to separate semen and urine, and it works as expected.

This was a lot of trial and error. The machine is good for the price however the rcf and speed don’t go up as high as other centrifuges so you may have to spin your sample longer. After reviewing others reviews of it shaking I would say the shaking is due to the user not balancing out the tubes. Remember the weight has to be the same on each side. I balance every time and have never had an issue with convulsive shaking. I spin a lot of SSTs in here for my mobile phlebotomy job and I haven’t heard a complaint about the quality of the specimen yet so I’d say it does what it’s supposed to.

Cumplió mis expectativas

It does the job I need it to do

No tubes provided. Usually the part numbers of tubes, consumables and replacement parts are included. Not on this product. No address or even a phone number for obtaining part numbers. The lid will not close which is a big safety concern because the only tubes I have been able to find have a cap that is tall enough to keep the lid from closing. It says it will accept a 20 mL tube. It does not with a cap on the tube.

Actual Max RPM is 2820 (890g RCF) making half the power as stated. Timer doesn’t turn the machine off so not sure what the point is.Measured max RPM (see pic) 47Hz = 2820 RPMMeasured with vibrocheckerDiameter is 20cm (radius 10cm)Measurements at various knob settings1/2: 960 RPM 103g RCF5/8: 1320 RPM 195g RCF3/4: 1920 RPM 412g RCF7/8: same as maxTubes are 20cc 10cm depth 18mm ID2.7ml tubes will sit low so added something in bottomTimer doesn’t function to turn off the device nor does it have a bell or something.Noise is as expected, not overly loud.Value I would still say is worthwhile given excellent price, will work for most needs as long as your RCF requirements are low.Why lie about the power. If it wasn’t for that I’d be happy to rate 5 stars for now. Will see how long it lasts.

Easy and convenient.For lab work.
