Cryopreservation is the process of preserving biological samples at extremely low temperatures, typically between -80°C to -196°C, to halt cellular metabolism and maintain long-term viability. This technique is crucial for research, medical treatments, and biobanking
Liquid nitrogen biological containers are designed to store various biological samples, including cells, blood, sperm, eggs, cord blood, and other critical specimens used in medical and research applications.
LBC is specifically designed for long-term storage of cryovials using square racks and cryoboxes, making it ideal for research and clinical use. In contrast, LC is used for storing straw tubes inside round canisters with aluminum canes, commonly used in reproductive and veterinary applications.
Before use, inspect the container for any visible damage. Pre-cool it by filling one-third of its capacity with liquid nitrogen, allowing it to stabilize for about two hours before completely filling it. This helps prevent thermal shock and ensures optimal performance.
The liquid nitrogen level can be measured using a level gauge ruler (1m) designed for precise readings. Avoid using hollow tubes or inappropriate tools, as they can cause splashing and pose safety risks.
It is recommended to monitor the liquid nitrogen level regularly and refill when it drops below 30% of the total capacity. This ensures that samples remain in optimal cryogenic conditions and are not exposed to temperature fluctuations.
Since liquid nitrogen evaporates into nitrogen gas, it can displace oxygen in enclosed spaces, creating a risk of asphyxiation. Proper ventilation is essential, and in confined areas, an oxygen detector should be used to ensure safety.
Always wear cryogenic gloves and protective eyewear when handling liquid nitrogen to prevent frostbite or burns. Avoid touching metal surfaces directly, as they can cause skin damage. Additionally, never tamper with the vacuum port and always keep the neck plug dry to maintain insulation efficiency.
If excessive condensation or ice buildup appears on the container's exterior, it may indicate a vacuum loss, leading to increased liquid nitrogen evaporation. If this occurs, contact technical support immediately for assessment and potential replacement.
No, liquid nitrogen biological containers are specifically designed for LN2 storage. Using other liquids may damage the insulation, compromise the vacuum seal, and contaminate stored samples.
Only polycarbonate (PC) cryoboxes are recommended, as they are specifically designed to withstand ultra-low temperatures without cracking. Other materials may become brittle and fail under cryogenic conditions.
Various accessories are available to enhance usability and safety, including cryogenic gloves for hand protection, a five-wheel roller base for easy mobility, and a level gauge ruler for accurate LN2 level monitoring. These accessories help ensure safe and efficient handling of the container.
