We newly developed Cryotop®CL for closed vitrification and preservation, applying the benefit of Cryotop®.
Cooling speed for closed vitrification drastically drops when compared with open vitrification. Conventional Cryotop® has the cooling speed of -23000°C/min whereas the average of other brands cooling system is less than -2000°C/min. Kitazato put together various ideas and technologies and succeeded in raising the cooling speed of Cryotop®CL to -3000°C/min.
