The Cryotec® method is a patented ultra-rapid cryopreservation technology developed by renowned Japanese scientist Dr. Masashige Kuwayama. The primary goal of Cryotec® is to standardize embryology workflows and ensure consistent 100% survival rates for human oocytes, cleavage-stage embryos, and blastocysts post-thaw.
By instantly converting intracellular liquid into a solid, glass-like state without ice crystal formation, the method completely eliminates mechanical cell damage and supports outstanding clinical pregnancy rates in ART cycles.
Proven Clinical Efficacy: Optimized media formulations combined with uniquely designed carriers allow clinics to achieve maximum specimen survival regardless of the developmental stage.
Integrated Consumable System: Dedicated Cryotec® and Cryotec® PRO carriers with protective caps, along with ergonomic and Plastic Vitri and Warm Dishes, are designed for smooth micro-manipulations with zero optical blind spots under the microscope.
Contamination Protection: The carrier structure ensures secure, hermetic sealing and full protection of biological samples during initial immersion and long-term liquid nitrogen storage.
Japanese Quality Assurance: All system components are produced in cleanroom conditions under strict quality controls, passing mandatory embryo toxicity (MEA) and endotoxin (LAL) testing.
The complete step-by-step procedure for freezing and thawing is fully detailed in our official Cryotec® protocol guide.
