There are a few different options you can get if you need test tube centrifuges. Some 8 Place porta-fuges have a fixed speed (3000 RPMs), which makes them perfect for portability. They accommodate a number of test tubes from 3 to 15 ml. Economical 8 Place varieties feature virtually maintenance-free motors, too. There are also C-5 centrifuges for sale that go up to 5,000 RPMs and have convenient digital time/speed programming. Zip-spin models are also economical options that can prepare DNA, perform cell separations or microfilter HPLC samples. Browse our centrifuge machines below.
