I am looking for suggestions for cheap, but good centrifuges that we could use for Rh testing in tube. The one we currently have does not provide a good enough cell button at the manufacturer's recommendation. I am looking for one that we can have go from 0 seconds to whatever but also use for spinning of other specimen tubes if that is possible. If you have any ideas please pass them along! Thanks!!!!

If you have a Diamed card spinner you may be able to get the interchangeable head rather than getting a whole new centrifuge... I'm not sure what the model number is as the one I used was in my training days but one of the ones with the pull off card heads can be interchanged with a tube spinner.
