LONDON - s4story -- Cryogenic storage leaves no margin for error. At -196 °C, biological materials such as embryos, sperm, stem cells, and tissue depend on more than stable temperatures. They rely on a storage system that is structured, visible, and easy to manage. When organisation slips, risk creeps in. That's why a well-designed combination of Visotubes, Cryosleeves, Cryocanes, and Cryocane coloured coders makes such a difference.

Visotubes: Visibility and Order from the Start

Visotubes form the foundation of organised cryostorage. Designed to hold cryogenic straws securely, their compact cylindrical shape fits neatly inside storage tanks without wasting space. The clear plastic body allows instant visual checks, while multiple colour options support simple categorisation by patient, cycle, or sample type.

Colour-coded Visotubes reduce search time and help prevent handling errors. When retrieval needs to be fast and precise, that clarity matters.

Cryosleeves: Added Protection Where It Counts

Cryosleeves provide an extra layer of protection during storage and handling. Used over individual straws or in combination with Visotubes, they shield samples from direct exposure to liquid nitrogen and reduce contamination risk.

Their flexible design makes handling easier during loading and removal, especially in busy labs. Available in various sizes, Cryosleeves are a small addition that delivers meaningful protection and cleaner workflows.

Cryocanes: Structure Inside the Tank

Cryocanes bring order to the storage tank itself. These stainless steel holders keep Visotubes upright, evenly spaced, and stable. Built to withstand repeated immersion and handling, they are ideal for high-volume environments where reliability is non-negotiable.

By keeping samples aligned and accessible, Cryocanes make better use of available space and allow technicians to work efficiently without disturbing surrounding samples.

Cryocane coloured coders add a final layer of clarity. These brightly coloured tabs attach to the end of each cane, making identification immediate even when working deep inside a tank.

Each coder features a flat surface for marking or labelling, supporting clear identification of contents. Available in a range of colours, they simplify tracking, reduce retrieval time, and support clean inventory management during cryopreservation. In high-throughput settings, this visual cue can save valuable time and prevent costly mistakes.

One System. One Clear Workflow.

Used together, Visotubes, Cryosleeves, Cryocanes, and Cryocane coloured coders create a storage system that is logical, efficient, and easy to maintain. Samples stay protected, organised, and clearly identified from storage to retrieval.

This integrated approach supports safer handling, smoother workflows, and greater confidence in long-term storage. It's particularly valuable for IVF clinics, research laboratories, and biobanks where accuracy and speed go hand in hand.

If you're setting up a new Cryostorage system or refining an existing one, the right accessories make all the difference. These aren't extras. They're practical tools that help your lab work better, every day.
