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.
- Utilizes capillary action for simple loading with a defined solution volume.
- Protect samples from evaporation and mechanical damage during handling.
- Simplifies warming and dilution into a single step and utilizes the mild pressure from the expanding warm air to ensure safe expelling.
- Uniquely suited for cryopreservation of biopsied or zona-free embryos due to the protection provided by the straw, the lace of adhesion to surfaces and trauma-free loading/expelling.
The Open Pulled Straw (OPS) was the first purpose-designed tool for ultra-rapid vitrification, and the vitrification method that offered solution for aseptic storage, the sterile container-straw technique.
