The vapor phase liquid nitrogen tank is a device used for low-temperature storage of experimental samples such as stem cells, plasma, semen, embryos, various tissues and organs. It can accommodate large quantities of biological samples for long-term static storage, and has both liquid and gas phase storage methods. Compared with traditional liquid nitrogen containers, it is more powerful. Let's talk about the advantages and characteristics of the vapor phase liquid nitrogen freezer in detail.
1. Intelligent supervision: equipped with an intelligent monitoring and management system, it can realize automatic monitoring of the temperature in the tank, abnormal reminders, remote alarms, event recording and automatic rehydration, saving time and effort, safe and reliable.
2. High-density storage: large volume, usually between 350-1800 liters, with higher space utilization, can store a large number of samples.
3. Dual storage mode: provides two modes of liquid phase storage and gas phase storage. The gas phase storage mode uses low-temperature nitrogen evaporated from liquid nitrogen to store samples, avoiding the possible bursting of the cryopreservation tube when it is taken out, and the problem of cross-infection of samples. â??
4. Stable opening temperature: The unique large-caliber slanted mouth design can reduce liquid nitrogen loss when opening the lid and maintain the stability of internal temperature changes. â??
5. Temperature monitoring system: The monitoring system can display the temperature inside the tank in real time with high accuracy, and users can set alarm points by themselves.
The above are the advantages of stem cell liquid nitrogen tanks, making it an ideal choice for biological sample storage, ensuring the safety of samples and the effectiveness of long-term preservation.

Features: High strength and high corrosionproof, provides long service life and convenient to fill and clean. It provides wide applicability and can be widely applied for packaging in industries such as chemical engineering, petroleum, medicine and food etc. Seal liquid test:Put the sealed barrel with liquid upside down or tap,the seal is at the lowest position,and no leakage within 24 hours. The standard specifies blow-moulding technology requirements of the barrel, test methods and the rules and symbols, packaging, transporting and storage. This standard applies to polyethylene as the main raw material, barrels production through automatic blow molding machine,and this type of blow molding barrel is mainly used for solids or chemical products. We also can help to change any design as your requirements. such as size,weight,color,capacity ect.

This is chemical setting Furan based chemical resistant mortar which is combination of Liquid and Powder, when mixed in proper proportion from workable mortar which after setting and curing give of liquid and give black highly cross linked composites. Furan When set and cured is resistant to highly corrosive acids, alkalis and to powerful organic solvents such as ketones, Aromatic and Chlorinated solvents. It has extreme resistant to Acidic & alkalis, Salts, Greases and Detergents. It resists to Organic & Inorganic acids at their boiling temperature. It is suitable against mild chlorine Gas (dry) phosphorous trichloride, pyridine at room temperature. Furan is especially useful where resistance to mixed media such as aqueous acids /alkalis and organic solvents is needed in chemical plant process and waste streams. Carbon filled Furan is used against corrosive effect of hydrofluoric acid & its salts. PREPARATION OF FURANE MORTAR : Mortar consist of Furan solution and Furan powder. The average mixing ratio necessary to obtain mortar with good working consistency is 1 part by weight Solution & 3 part by weight powder. The ratio will vary slightly depending on temperature and working conditions.Stir the liquid thoroughly before using. Place liquid in a suitable shallow mixing pan. Add powder by weight in the solution mix thoroughly and rapidly until all lumps are dispersed and the mortar is completely homogenous. Spread out the mortar in a thin layer, not more than ¾ thick, to dissipate the heat of reaction and lengthen the working life. Batch size can be varied depending upon the temperature and the speed with which the masons are working. Very large batches will become stiff quite rapidly. Make sure that all the Furan Motrar is used from the pan before another batch is mixed.When working at temperature above 40 C, very small batches not more than 2 Kgs, should be prepared. When working at temperature below 15C the liquid should be kept warm.
