Open Pulled Straw (OPS) Vitrification Device

Open Pulled Straw (OPS) Vitrification Device

Widespread application of vitrification for cryopreservation of oocytes and embryos is one of the most significant achievements in human assisted reproductive technology (ART) during the past decade.

The Open Pulled Straw (OPS) was the first purpose designed tool for ultra-rapid vitrification. 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.

To date , OPS has resulted in:

• The first human baby after oocyte vitrification
• The first cloned animal after embryo cryopreservation
• The first calf after cryopreservation of immature oocytes
• The best survival-developmental rates after cryopreservation of human ES cells.

In collaboration with Professor Vajta, VitaVitro is proud to present the long awaited, complete OPS kit, including straws, media, related tools and technology transfer.

The VitaVitro OPS kit is also the only commercially available vitrification method that offers direct online consultation with the creator of the technique, providing a unique guarantee for efficiency and reliability.
