  • TDD-Series

  • TOP

Application area

Widely used by scientific research institute,medical,animal,plant and marine institutes for research of metallics under low  temperature, long-time storage of DNA,RNA,stem  cells, plasma, seminal fluid,embryo,tissue and organ and other bulk biological samples,cryogenic treatment of metallic materials and change of metallographic structure of metallic materials; significantly improve hardness,strength and wear resistance of metallic materials.

Product   advantages

Use design of gas/liquid phase

Prevent contact with liquid nitrogen and cross infection of samples when used in gas phase

Scientific storage design

Higher capacity of sample storage than 2ML standard cryopreservation tube(13000-125800 samples)

Strong insulation performance

Advanced pumping,insulation and high vacuum holding technologies used to ensure safe storage of samples and uniform temperature.

Hot gas bypass design

High-temperature  nitrogen  discharged  prior  to  liquid  nitrogen  filing  to  avoid  internal temperature fluctuation,ensure sample safety and effectively reduce unnecessary liquid nitrogen consumption

Automatic liquid filling and continuous liquid level monitoring

Capacitive sensor used for measuring internal liquid level that is displayed timely to ensure safe and reliable liquid filing
