SafePreservation scientists have developed a new system that improves cryopreservation closed survival rates and fertility of gametes and embryos after the passage of the years compared to other closed systems. As compared to traditional semi-open straws, SafePreservation provides extra secure preservation of gametes, eliminating direct contact with liquid nitrogen that keeps -196, and eliminating the risk of contamination.

This is a new straw laminated at both ends, which means that the solution containing the gamete or embryo is hermetically sealed at both during the freezing process, and during the years of preservation, and at the time of thawing. SafeSpeed ​​is the result of research carried out by the spin-off of the University of Seville SafePreservation, for over ten years and has been proven through various clinical trials for three years.

In this process, accompanied them Ginemed, who after appropriate tests have concluded that the new method surpasses the previous closed system in terms of survival rates of oocytes, sperm, embryos and bastocistos and their ability to fertilization. Media as Telecinco, La Vanguardia, Europa Press or Economist echoed the news became.

Vitrification Technique

The Vitrification process must initially prepare samples in special glazing medium and subsequently introduce in the support SafeSpeed Device between the 2nd and 3rd mark by the method of aspiration with the connector. Once satisfied that the sample is well placed in the holder, heat seal the fine capillary with SafeSealer accessory brand below 1. Finally, the support should be immersed in the sealing vessel SafeBox Liquid Nitrogen filling and slide protective case support

Warming Technique

For the warming process is necessary to prepare the SafeBox container with liquid nitrogen in a tank and water at 37 ° C in the other tank within 15 cm of the cryocane. Then you have to carefully slide the plastic cover up, to make sure the capillary is completely immersed in liquid nitrogen and in less than a second inmerse it in the hot water tank. Finally, place the bracket SafeSpeed in a cutting system to cut it just above the heat sealing in the external wider and below the 1st mark and expel the sample.
