-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.
