What are vitrification straws?
Vitrification straws are the carriers that hold oocytes and embryos during ultra rapid freezing. They come in open and closed types.
How do open and closed straws differ?
Open systems allow direct contact between the sample and liquid nitrogen for very high cooling rates. Closed high security straws seal the sample away from direct liquid nitrogen contact, protecting against the potential risk of cross contamination during storage.
Which type should a clinic choose?
Research shows closed high security systems achieve outcomes comparable to open systems while adding contamination protection. Cryolab supplies vitrification straws for clinical practice at cryolab.co.uk/shop/.
