Monitoring management system for liquid nitrogen biological container of cord blood stem cell bank is a system integration product that was studied and developed for five years by our company. By drawing advanced management experience of cord blood stem cell bank at home and abroad, our company uses creatively advanced data collection technology, communication technology, automatic control technology, and embedded software technology. The system is mainly made up of remote terminal unit (rtu) of intelligent monitoring of biological container and data service center (dsc). Intelligent monitoring terminal unit has the following functions: real-time collection of temperature of low and high position, real-time monitoring of liquid height, calculation of liquid nitrogen loss, automatic switch of liquid inlet electromagnetic valve according to liquid level and temperature, internal local area network is used to connect tank body computer with server of monitoring center, dtu sends warning message to the cell phone of watch keeper including low-and-high-position overheating warning and sensor failure warning, powerful mis management system for objects in cryopreservation, and so on. Data monitoring center analyzes and stores data provided by rtu and these data are investigated by management staff. Monitoring terminal unit can check conveniently the state of every network monitoring terminal by connection of local area network and monitoring center on a computer in the monitoring center without reaching any biological storage container. Monitoring center computer is also in charge of storing and managing all objects stored or to be stored in the liquid nitrogen tank. Monitoring center software is mainly made up of eight major modules including operation model selection, data monitoring, alarming, and object information management.
Application range: It is also appropriate for long-term static preservation of a large number of biological samples such as stem cell, plasma, semen, embryo, tissue, organ, and so on. Production technology: Unique patent technology of evacuation and multi-layer insulation technology ensure an extremely low loss rate of liquid nitrogen evaporation. All weld joints go through mental flaw detection and helium mass spectrometer to see if there is leak. Every product goes through strict liquid nitrogen test. Unique polishing technology ensures aesthetic modeling. The entire manufacturing process follows strictly iso9001:2008 and iso13485:1996 quality control procedures. Production materials: Materials of inner tank and outer tank are made of 304 austenite stainless steel of fine quality. Adsorbents are all regenerated and activated. Materials of multi-layer insulation are made of oil-and-lipid-free thin composite. Product feature: 1.-196 degree immersion cryopreservation and -190 degree vapor cryopreservation can alternate freely 2.Effective insulation ensures 98% of system surface is shrouded by vacuum 3.Powerful control and management system, automatic fluid infusion, real-time monitoring of liquid level, temperature and other data are installed 4.Compared with equipments of same functions, it saves 70% of liquid nitrogen and reduces maintaining costs to the lowest degree. 5.Pallet rotation in the inner tank makes access convenient.

In scientific research institutions or pharmaceutical companies, some biological samples need to be stored in liquid nitrogen sample storage tanks. Liquid nitrogen sample storage tanks are an important cryogenic storage equipment that many people are not familiar with. So as a manufacturer of KGSQ liquid nitrogen tank, let me briefly introduce how to use it. 1. Before use, you need to carefully check the appearance to see if there is any dent or damage, and whether the vacuum exhaust port is intact. These inspections are to ensure that the thermal insulation performance of the liquid nitrogen tank is good. 2. Liquid nitrogen tanks rely on liquid nitrogen to ensure deep and low-temperature storage, so the tanks can only be filled with liquid nitrogen. Mixing other flammable substances can easily cause interaction and cause an explosion. 3. The liquid nitrogen tank container should be placed in a cool, dry place to ensure good indoor ventilation. 4. The temperature of liquid nitrogen is -196�°C. Self-protection measures should be taken when extracting and storing the freezing rack, such as wearing leather or cotton gloves. Be cautious when operating with bare hands. At the same time, it is necessary to prevent liquid nitrogen from splashing, which may cause frostbite when it touches the skin and other parts. 5. When filling liquid nitrogen for the first time, because the vacuum liner is at normal temperature, it is not advisable to fill it too fast. A small amount should be injected first to gradually reduce the temperature of the liner. Injecting a large amount of liquid nitrogen can easily cause the liquid nitrogen to boil. At this time, slow down. Wait for the liquid nitrogen to cool down slightly before injecting liquid nitrogen faster. Otherwise, the liquid nitrogen will boil and splash outward, causing frostbite. 6. Liquid nitrogen should not be overfilled, and the liquid level should not be in contact with the fiberglass neck tube. 7. Liquid level height check: Insert a wooden ruler vertically into the center bottom of the liquid nitrogen tank and take it out after about 15 seconds. The frost length is the liquid level height. Never use a hollow tube for inspection to prevent liquid nitrogen from erupting from the tube and injuring people. 8. Make sure that the liquid nitrogen submerges the refrigerated items. When the liquid nitrogen is consumed to the point where the refrigerated items are about to be exposed to the liquid surface, liquid nitrogen should be replenished in time.
