Biological liquid nitrogen container

Stainless steel biological liquid nitrogen container (stem cell bank and bio-medical use only)

Overview:

Large caliber biological liquid nitrogen container of stainless steel is a state patented product (Patent No: ZL200720081948.X, ZL201120352301.2). It is an innovative product that draws on technical essence of foreign excellent products and meets many industrial demands. It uses liquid nitrogen as refrigerant so that it meets the needs of low-carbon cooling and environmental protection. Various technologies are used in this product such as latest high vacuum multi-layer insulation technology, computer software technology, electronic temperature control technology and liquid nitrogen dispersion technology, which stabilize every process of intelligent cooling and constant temperature control and reduce the loss rate of liquid nitrogen because of evaporation and using cost to the lowest degree. This product offers immersion cryopreservation and vapor cryopreservation in hopes of satisfying diverse cryopreservation needs of users to the greatest degree.

Product Standard:

Chinese Standard: GB14174-93

A

pplication Range:

It is 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 ISO 9001:2008 and ISO 13485:1996 quality control procedures.

Production Materials:

Materials of inner tank and outer tank are made of 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°C immersion cryopreservation and -190°C 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.

B. Stem Cell Bank Monitoring Management System for Liquid Nitrogen Biological Container

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.
