Centrifuge: (for ttc a girl) -you will need to find a plug in adaptor for your centerfuge
**People have found buying a real centerfuge off of ebay works MUCH better.. keep you eye out for a cheap one (around 50$ plus shipping )and a slower one. You want to find one that does a speed of 3000rpms or slower.
