cryogenic nitrogen dewar flask for storing biological samples

   The liquid nitrogen tank commonly known as biological liquid nitrogen container, in the rapid development of science and technology today, the use of the liquid nitrogen tank is more and more widely. It not only can be used for medical, biological research, University experiment and prevention unit, more commonly used in the life of beauty, wedding and other industries, the use of it in line with the social development, to meet the different customer groups. For medical and scientific research on the tank is the main storage type liquid nitrogen container, used for static indoor long time preservation of bovine semen, embryos, stem cells, skin, internal organs, vaccines and other bioactive material.

Liquid Nitrogen Tank Specifications

Product advantage

1.Inner liner is made of high strength aluminum alloy, sturdy and durable.

2.Between the liner and the outer liner is a high vacuum, vacuum film with multilayer imported insulation material, therefore has good refrigerating performance.

3. Neck plug is made of nontoxic plastic good adiabatic property, it has dual role to reduce the liquid nitrogen evaporation and fixed lifting cylinder.

4. Neck tube is enhanced compounds made of glass, it has the extremely low thermal conductivity, can be put into the external heat control at the lowest temperature from cervical canal.

5.In a vacuum, part of which is provided with a gas adsorbing agent, it can adsorb gas metal vacuum cavity or other substances volatile out, thus maintaining a high vacuum.

Product Packaging

1.Export standard packaging.
2.Neutral bleached paper carton.
3.Double corrugated boxes.
4.Foam packaging,belt on the carton ,rainproof ,Crack control.

Application field of the liquid nitrogen tank

the application in animal husbandry
1, widely used in livestock improvement skills in a variety of domestic animals with frozen semen cryopreservation for cattle, preparation, survival skills, since the last century fifty years has formed a complete set of shaping process.

2, the cattle embryo transplantation and a variety of animal, the preparation of surviving embryos

3, the ultra low temperature of liquid nitrogen microbial skills

4, agricultural biological gene survival

5, the survival of the liquid nitrogen vaccine

6, use liquid nitrogen treatment of cow nipple hole outside the mouth closed, the cattle skin tumors are more common. 
the application in medical miracles
1, low temperature medicine

To promote the growth of transplantation medicine, especially in the bone marrow, the hematopoietic stem cells, skin, cornea, endocrine glands, and blood vessels and valves and other frozen survival and transplantation has achieved remarkable results.

2, clinical medicine
Liquid nitrogen is now the most widely used in cryosurgery refrigerants. Is one of the best refrigerant now present, put it into the medical device operation in low temperature, like a knife like, can do any operation. Freezing is a method of treatment for low temperature to crush lesion structure. 
the application in food industry
1, The application of liquid nitrogen in freezing of food.
The freezing rate (fast freezing rate than usually freezing method is about 30-40 times faster)
The link food character
The material dry consumption
The set of equipment deployment and dynamic cost low, easy to realize mechanization and automation of production line, improve productivity.

2, Application of liquid nitrogen in the beverage processing

3, Liquid nitrogen storage application in fruits and vegetables preservation of
Liquid nitrogen for fruits and vegetables fresh-keeping storage with adjustable gas strengths, can adjust agricultural season and the off-season supply and demand contradiction, out of storage loss.

4.Application of liquid nitrogen in the meat product processing 
Liquid nitrogen material in process meat stranding, chopping or confused in the syndrome, can effectively improve the product quality.

5.Application of liquid nitrogen in food cryogenic comminution. 

6, The application of liquid nitrogen in food packaging.

7, Liquid nitrogen application in the transportation of refrigerated food.

8,Other application of liquid nitrogen in food industry. 
in the electronics industry in the application
1, superconducting skills

2, electronic components manufacturing and testing

3, cryomilling skills

4, green machining skill 
other areas

It is pushing agent rocket fuel, large amounts of liquid nitrogen with high pressure to rocket fuel to the combustion chamber.

Applied in HTS power cable to open.

Liquid nitrogen artificial rainmaking skills.

The admission of nitrogen underground fire.

Products use guidelines

1, Liquid nitrogen is ultra low temperature products (-196 ℃), in use process to prevent frostbite.

2, Operating in liquid nitrogen freezing and access items faster, pay attention to gentle with, avoid content thawing, causing unnecessary losses.

3, In the use and storage of liquid nitrogen in the room, to maintain good ventilation, to avoid space hypoxia, cause choking.

4, Because the liquid nitrogen without sterilization, so the contact of liquid nitrogen appliances should pay attention to disinfection.

5, Transportation using transport tanks, banning use of the storage tank .

6, Liquid nitrogen tank vacuum nozzle valve seals seals, quiet, can not damage.

7,  Liquid nitrogen tank storage items for a long time, pay attention to the timely supplement of liquid nitrogen.Liquid nitrogen level is not lower than cold storage items as appropriate.

8, Check the liquid nitrogen storage, can use weighing method or the flashlight beam method, can also be fine wood, bamboo poles into the liquid nitrogen tank in the frost height (equal to the height of liquid level) method. But do not use a hollow tube insertion, in order to avoid the liquid nitrogen from the tube out of spatter wounding.

The liquid nitrogen tank maintenance
   The liquid nitrogen tank idle when not in use, should rinse with clean water, the water drainage, the blower for drying at room temperature, placed ready. Liquid nitrogen tank of liquid nitrogen volatilization after, left missing material (such as frozen sperm) melt quickly, into a liquid material attached to the liner, the liner of aluminum alloy will cause corrosion, if the formation of cavity, a liquid nitrogen tank will be scrapped, so the liquid nitrogen tank of liquid nitrogen after depletion on jar in brushing is very necessary the. The specific measures are as follows: first the scrubbing liquid nitrogen tank within tube removed, liquid nitrogen is removed, placed 2 to 3 days, until the tank temperature up to 0 ℃ , and then inverted 30 degrees around the warm water, scrub with a cloth. If discover the individual melted material stick in the liner on the bottom, be sure to carefully wash clean. And then rinse with water several times, then inverted liquid nitrogen jar, placed in the indoor safety should not be overturned, the natural air dry, or as before the blower for drying. Note that in the brushing process, action to despise, pour the water temperature can not exceed 40℃  , the total weight of not more than 2kg is appropriate.
