Phase Change Material Specifically For The -27°C Cold Chain, Intended For Use In Cold Storage Equipment Of Biobanks.

-27°C Cold Chain Specific Phase Change Material For Use In Cold Storage Equipment For Biobanks

Features:

1. Efficient heat storage and heat release capacity

• When the temperature reaches the phase change point, the phase change material can quickly absorb or release a large amount of heat. For -27 °C phase change materials, when the temperature rises close to -27 °C, it will change from a solid state to a liquid state, absorbing heat, thereby slowing down the temperature rise of the surrounding environment; When the temperature drops, it changes from a liquid state to a solid state, releasing heat and preventing the surrounding temperature from getting too low. For example, when transporting frozen food, phase change materials can maintain a relatively stable temperature around the goods through their own phase change when the outside temperature fluctuates.
• Its heat storage capacity is generally measured by the enthalpy of phase change, and the larger the enthalpy, the more heat can be stored and released, and the more beneficial it is to maintain the stability of the low temperature environment.

2. Accurate phase change temperature

• A phase change temperature of -27°C is essential for some goods that require extremely low temperatures for storage.
• For example, some special biological products, some frozen experimental samples, etc., require storage at a temperature close to -27 °C. This phase change material can precisely control the temperature within the appropriate range through the phase change when the ambient temperature is close to the phase change temperature.

3. Stability

• In terms of chemical stability, in a low temperature environment, phase change materials cannot react chemically with the goods, otherwise the quality and performance of the goods will be affected. For example, it cannot chemically react with frozen pharmaceuticals or biological samples to cause them to deteriorate.
• Physical stability is also critical, and the material must not exhibit significant volume changes, leaks, etc., during repeated phase transitions. For example, if a PCM changes too much in volume during the transition between solid and liquid states, it can disrupt the packaging and compromise the integrity of the cold chain.

Fields of application:

1. Storage of biological samples

• In medical and biological research, many biological samples, such as blood, tissue samples, etc., need to be stored at extremely low temperatures. -27°C cold chain PCMs can be used in the cold storage equipment of biobanks to maintain a stable temperature in the sample storage environment.
• When the external temperature fluctuates, the phase change material absorbs or releases heat through the phase change, ensuring that the sample is always in a suitable low temperature environment, ensuring the activity and quality of the sample, so as to facilitate subsequent analysis and research.

2. Frozen food transportation

• Some frozen foods, such as premium ice cream, special frozen pastries, etc., have very strict temperature requirements during transportation. PCMs at -27°C can be used in the cold chain transportation of these frozen foods.
• For example, when the temperature changes during transportation, the phase change material can maintain the temperature in the compartment or packing box close to -27 °C, prevent the frozen food from thawing and deterioration, and ensure the taste and quality of the food.

3. Low-temperature scientific research experiments

• In some cryogenic science research experiments, it is necessary to precisely control the temperature of the experimental environment. -27°C cold chain special phase change materials can be applied to the temperature control system of cryogenic experimental equipment.
• For example, in some physical experiments, where the experimental sample needs to be cooled to a temperature close to -27°C and kept stable, PCM can be used as a reliable means of temperature regulation. By rationally designing the use of phase change materials, the experimental temperature can be accurately controlled, and the accuracy and reliability of the experimental results can be improved.
