China TIANCHI Industrial dewar vessel YDS-3  is filled, it is necessary to check whether the housing has a depression and whether the vacuum exhaust port is in good condition. If it is damaged, the degree of vacuum will be reduced. In severe cases, the intake air cannot be kept warm, so that the upper part of the tank will be frosted, and the loss of liquid nitrogen will be large, and the value of continuing use will be lost.

The large capacity of 3L makes it widely used in many fields such as medical, scientific research, animal husbandry, and mechanical processing.

Henan Tianzhidao Biological Technology Co., Ltd. owned container of liquid nitrogen container production of the latest technical equipment and testing means of modern enterprise. The production of liquid nitrogen containers are widely used in livestock breeding livestock semen frozen storage; medical and health industry in human organs, skin, blood, cells cryopreserved; bio-engineering, industrial cooling assembly, cold treatment of metallic materials, low temperature, such as crushing and the majority of the field of superconductivity.
Since we strictly control the quality strictly in accordance with national standards “GB/T5458 liquid nitrogen biological container” organization of production, to ensure that each product 100% qualified .And access to GB/T19001-2000 quality management system certification. All staff to adopt a scientific attitude, strict management, so that products are sold throughout the country. And products are exported to all over the world, bulk export of Thai/ Vietnamese /Korean/Korea/Australia/ Ukraine /Mexico and other places.
