The characteristics of Cryogenic Tubes
Cryogenic Tubes are typically made of high-quality polypropylene (PP), a material that boasts excellent chemical stability and mechanical strength, and can maintain its physical properties at extreme temperatures, ranging from the gas phase temperature of liquid nitrogen (approximately -196°C) to the autoclave temperature (121°C). They are designed with particularly tight sealing caps, which can effectively prevent liquid leakage and the entry of external contaminants, ensuring the safe preservation of samples. They also have the ability to withstand extremely low temperatures and are suitable for long-term storage in liquid nitrogen or ultra-low temperature refrigerators, guaranteeing the stability of samples. For the convenience of identification and management, many cryogenic tubes provide white writing areas or Spaces where labels can be affixed. Meanwhile, in order to distinguish different types of samples or processing steps, cryogenic tubes may offer multiple color options. To avoid cross-contamination and maintain the purity of the samples, cryogenic tubes generally adopt disposable sterile packaging. These characteristics make Cryogenic Tubes an ideal choice for the long-term safe preservation of biological samples.
