Not just the best proven results on the market, now also the best user experience.

Achieve the highest survival rates on the market with the Cryotop® Method, the global leader in vitrification of oocytes and embryos in all stages of development.


The revolutionary device by Kitazato has been applied in over 1,500,000 clinical cases for oocytes and embryos with this method of cryopreservation during the last decade, obtaining excellent results in over 90 countries and 2,200 assisted reproduction centers. The Cryotop® method is simple, safe, universal and easy to apply for everyone.


Cryotop® Features

Wider Strip: The strip’s been widened. With a bigger surface, it is even easier to load the specimens.

Easier Insertion: The diamond tip, the reshaped conjunction between strip and handle and the widened body grant a smoother insertion into the cover straw.

Identification Marks: The Cryotop® has now two identification marks on its upper surface, defining the side where the specimens should be loaded, if you are vitrifying, or are loaded, if you are thawing.


Cryotop® is a vitrification device consisting of a fine strip of transparent film attached to a plastic handle resistant to liquid nitrogen. Its design allows the loading of specimens for vitrification with a minimum volume (0.1 µl), providing the best Cooling and Warming rates on the market (-23,000ºC/minute and 42,000ºC/minute respectively) which in turn lead to the best survival rates.


Main Characteristics

  • Allows up to 4 specimens to be loaded per device.
  • It has an external covering to protect the Cryotop® once vitrified. Tip with weight to prevent floating in liquid nitrogen.
  • Manufactured in malleable plastic resistant to liquid nitrogen.
  • Available in packs of 10 units.


Highest survival rates

Cryotop® Method offers proof of its outstanding results. Our survival rates over 90% are backed up by numerous clinical studies with the biggest sample sizes in the market.
