• The CryoFloater is a non-sterile floating device made of Polyethylene.
• Its intended use is to float on liquid nitrogen carrying straws or vials of prepared sperm/semen for liquid nitrogen vapour freezing.
• It 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.
• It has been tested extensively to determine the optimal height over the nitrogen surface.
• It also serves as a perfect back-up system in the case of brake-down of a programmed-freezer.
• Furthermore, it is quite inexpensive considering its usefulness.

• Polyethylene foam

Performance Characteristics

Distance above liquid nitrogen surface:

• Straws 15 mm
• Vials 20 mm

Do not store in direct sunlight.

• CryoFloater does not represent any kind of fire or combustion hazard. A material safety data sheet is available from the distributor or manufacturer.
• Not for drug, household or other uses.
•  Federal Law (USA) restricts this device to sale by or on the order of a physician.
• Please check for regulatory compliance governing the use of ART products in your country.
• Discard with normal waste.
• Do not use if broken.

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.
