Colombia Cell Storage Liquid Nitrogen Tank KGSQ

The Colombia Cell Storage Liquid Nitrogen Tank KGSQ is a dual-walled vacuum-insulated container designed exclusively for storing liquid nitrogen at -196°C. It consists of an inner vessel, outer shell, neck tube, polyurethane foam neck plug, and removable storage buckets. The tank’s design minimizes boil-off by reducing heat transfer, with the neck plug serving as a critical thermal barrier. This model does not support storage of any other cryogenic liquids and is engineered for biological sample preservation only.

The neck plug is constructed from high-density polyurethane foam, a material chosen for its low thermal conductivity and resistance to liquid nitrogen absorption. It is lightweight, non-adhesive, and mechanically secure, preventing displacement during handling. Standard industry practice requires the plug to remain in place during storage to limit nitrogen evaporation to less than 1.5% per day under typical lab conditions. Without it, evaporation rates can increase by up to 400%, risking sample degradation and safety hazards.

This tank is used by research laboratories, biobanks, and medical facilities storing human tissues, sperm, eggs, and cell lines. Buyers typically order in quantities of one to five units, with standard packaging in wooden crates for international shipping. Incoterms are usually FOB Zhengzhou Port, and lead times are confirmed after order placement. Buyers must verify ventilation requirements for indoor storage and confirm the tank’s pressure relief valve certification before use.

Henan Tianzhidao Biological Technology Co., Ltd. is based in Zhengzhou, Henan Province, China, operating from a facility located in the High-Tech Industrial Development Zone. The company’s listing shows no verified certifications, no published factory audit reports, and no public history of export volume or client references. Response metrics indicate no buyer inquiries have been answered, suggesting limited customer engagement.

The supplier specializes in liquid nitrogen storage equipment and produces models under the KGSQ brand. There is no indication of ISO certification, third-party testing, or compliance with international cryogenic standards such as ASME or EN 13009. The company does not appear to offer after-sales service documentation or installation guidance. Buyers should treat this as a manufacturer with unverified operational transparency and request independent testing before large orders.
