VITAVITRO® OPEN PULLED STRAW (OPS)

The first purpose-designed tool for ultra-rapid vitrification. VitaVitro Sterile Container-Straw Technique: the first vitrification method that provides solution for aseptic storage. Introduced by Professor Gábor Vajta in 1998, OPS is recognized as one of the best high-rate cooling-warming vitrification methods, widely respected for its efficiency, practicality, and versatility.

BENEFITS

  • Reliable performance through original design
  • Stable volume of vitrified solution
  • Oocytes or embryos do not attach to the carrier tool
  • User-friendly design provides superior protection and ensures high in vitro and in vivo developmental competence after warming

AMONG OTHER SIGNIFICANT ACHIEVEMENTS, OPS HAS RESULTED IN:

  • The FIRST human baby after oocyte vitrification (2001)
  • The FIRST cloned animal after embryo cryopreservation (2003)
  • The FIRST calf after cryopreservation of immature oocytes (2004)
  • The HIGHEST survival-developmental rates after cryopreservation of human ES cells (2008)
