CryoFloater Straw

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 of semen (or prepared sperm) when freezing with liquid nitrogen vapour. The CryoFloater provides a constant distance between the straws and the nitrogen surface, thereby allowing the sperm to freeze in the vapour, not in the fluid.

Features

1. The CryoFloater is a non-sterile floating device made of Polyethylene.
2. Intended use is to float on liquid nitrogen carrying straws of prepared sperm/semen for liquid nitrogen vapour freezing.
3. Provides a constant distance between the straws and the nitrogen surface as the nitrogen evaporates. The sperm will be frozen in the vapour of the nitrogen.
4. Tested extensively to determine the optimal height over the nitrogen surface.
5. Serves as a perfect back-up system in the case of brake-down of a programmed-freezer.
6. Quite inexpensive considering its usefulness.
