I use an old prescription bottle with a string tied around it...very low tech and not fancy, but it does the jobI actually used a small plastic hand operated centrifuge to do mine, that is until I broke the darn thing, haven't had the need to get another one, I would probably have to by the whole darn chemistry set to get another one but I don't need the other stuff out of it, I have enough lab glass as it is, well I could use some more test tubes though.Can't afford the electric ones, and well don't have real use for one. lmao
