Nidacon CryoFloater Straw

A simple and stable way of vapor freezing

The Nidacon CryoFloater is a device designed for use during the cryo-preservation of sperm with liquid nitrogen. CryoFloater functions as a floatation device, carrying straws or vials of semen (or prepared sperm) when freezing with liquid nitrogen vapour. The CryoFloater provides a constant distance between the straws/vials and the nitrogen surface, thereby allowing the sperm to freeze in the vapour, not in the fluid.
