  Working with cryogenic materials exposes laboratory staff to extreme cold and potential hazards, including frostbite, chemical burns, and splashes. Proper personal protective equipment (PPE) is vital for safety and regulatory compliance. Core PPE items include lab gloves, safety glasses, aprons, and face shields. Protecting Your Eyes Eye safety is a top priority in any laboratory. Safety glasses or safety goggles shield against splashes, flying particles, and frost injuries. Trusted brands such as Bolle and Uvex offer durable and comfortable eye protection. For those needing vision correction, options like prescription safety glasses UK, prescription sports glasses, and prescription safety spectacles combine clarity with safety. Bolle sunglasses can provide additional UV protection in bright work environments. Ensuring proper eye protection is fundamental in cryogenic labs. Lab Aprons for Body Protection Safety aprons safeguard the body from spills and extreme cold. Available in ...

  In IVF and assisted reproduction, every detail of cryogenic handling is crucial. Among the most important are embryo and sperm straws. These small, sealed tubes may seem simple, but they play a critical role in protecting genetic material during collection, freezing, storage, and thawing. Choosing the right straws ensures sample safety, traceability, and compatibility with laboratory workflows ( Cryopreservation – Wikipedia ). Embryo straws are thin, hermetically sealed tubes designed to store embryos, sperm, or oocytes in liquid nitrogen. Typically made from biocompatible plastic, these cryogenic straws prevent contamination or cross-mixing. In IVF laboratories, embryo freezing straws, embryo storage straws, and LN2 embryo straws are used for freezing, labelling, and thawing biological material during insemination, embryo transfer, or vitrification procedures. Features of High Quality Straws A reliable embryo or sperm straw should maintain integrity at ultra-low temperatures dow...

  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 Cryo...

Maintaining ultra-low temperatures is critical in  cryogenic storage . Eggs, sperm, embryos, and other biological samples remain viable only when stored consistently at  -196 °C . Even small temperature fluctuations can compromise years of research or clinical work. Across the UK, laboratories and fertility centres rely on  cryogenic tanks, LN2 tanks, and dewars  to keep specimens safe. What Are Cryogenic Tanks? A cryogenic tank is a specialised vessel for storing biological materials at extremely low temperatures using liquid nitrogen (LN₂). These tanks preserve samples long-term by maintaining stable temperatures below -196 °C. Cryolab’s CryoNest® range includes high-quality aluminium and stainless steel tanks designed for minimal nitrogen evaporation. Whether your lab needs a single cryogenic tank or multiple LN2 storage vessels, CryoNest® offers solutions tailored to any workflow. Dewars and Portable Cryogenic Storage Liquid nitrogen dewars  are versatile fo...
