The spermofuge has been designed to wash sperms for intra-uterine insemination (IUI) and other infertility treatments. The centrifuge is fully automated for speed and time controls adhering to WHO 2013 guidelines, so that the manual error related to irregular settings can be tackled, and the damage of sperms can be prevented.

The tube has been compartmentalized that separates pellet from supernatant after centrifugation and do not intermix even if disturbed. The design of spermofuge is fully compact and the light weight makes the device fully portable. The spermofuge is a perfect solution for new IUI clinical settings that do not want to indulge in hefty lab settings.
