Cryosleeves are PVC sleeves used to protect and identify cryogenic straws within a goblet or cane system inside a liquid nitrogen storage tank. Cryolab also supplies half cryosleeves for configurations where space within the goblet is limited. Colour-coding with cryosleeves enables rapid visual identification at the point of retrieval, a key patient safety mechanism in HFEA-licensed IVF storage facilities.
The combination of a labelled straw, a colour-coded sleeve, and a cryocane with an identification tab forms the multi-layer identification system underpinning chain-of-identity compliance. Cryomarker fine-tip permanent markers enable direct labelling onto the sleeve surface. In high-volume sperm banks and biobanking operations, consistent cryosleeve use as part of a documented labelling protocol is a key component of ISO 20387 quality management accreditation.
