Vitrification Straws

This disposable sterile vitrification cryovial is a specialized medical consumable developed for assisted reproductive technology (ART). It is designed for closed ultra-low-temperature vitrification cryopreservation of human oocytes, cleavage-stage embryos, blastocysts, sperms and reproductive tissues in professional IVF fertility laboratories.
Fabricated from medical-grade biocompatible polymer, the cryovial boasts superior cryogenic resistance, non-cytotoxicity and reproductive biosafety. Ethylene oxide (EO) sterilized and individually packed, each product passes qualified endotoxin testing, free of pyrogens and exogenous contaminants, fully complying with global ART laboratory medical specifications.
Equipped with an optimized thin-wall capillary structure, the cryovial achieves ultra-rapid cooling and warming rates during vitrification, which inhibits intracellular ice crystal formation effectively, and enhances the post-thaw survival rate and developmental potential of oocytes and embryos. Its fully closed integrated sealing structure isolates samples from liquid nitrogen and external pollutants, prevents cross-contamination among individual patient specimens, and guarantees clinical biological safety.
Built with ergonomic structure for easy lab manipulation. The weighted anti-floating base enables steady submersion in liquid nitrogen. The reserved writing area and multi-color coded handles facilitate standardized sample classification and management to reduce human errors. Smooth polished edges avoid mechanical damage to fragile reproductive cells during sample loading, transferring and thawing processes.
Compatible with mainstream vitrification-warming media and universal liquid nitrogen storage systems, this product applies to routine embryo cryopreservation, oocyte fertility preservation, sperm cryobanking, post-biopsy embryo freezing and long-term germplasm storage. Featuring high stability and easy operation, it is a indispensable core consumable for standardized vitrification procedures in reproductive clinics and IVF labs.
