The CryoFloater is a device used for the cryo-preservation of sperm with liquid nitrogen. It functions as a floating 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.
Distance above liquid nitrogen surface:
Do not store in direct sunlight.
Although it is possible to freeze unprocessed semen, we recommend that the ejaculate be prepared on a PureSperm density gradient and washed with PureSperm Wash before adding Sperm CryoProtec. This method removes seminal plasma as well as ROS and their sources, thereby ensuring optimal recovery of motile sperm after thawing.
