Diagnostic reagents are used for the diagnosis, detection, and epidemiological investigation of human diseases. It is divided into two categories: in vivo diagnostic reagents and in vitro diagnostic reagents.Diagnostic reagent freeze-drying machine is an equipment used for vacuum freeze-drying processing of diagnostic reagents using FD freeze-drying technology. Today, let's learn about the working principle of the diagnostic reagent freeze-drying machine.

Diagnostic reagents have high transportation costs, harsh conditions, unstable performance, and short shelf life;After processing with diagnostic reagent freeze-drying machineCan be stored at room temperature，NOT REQUIREDCold chain transportation,muchImprove product stability.The working principle of the diagnostic reagent freeze-drying machine is to use the sublimation principle. The prepared diagnostic reagent liquid is pre frozen and crystallized into a solid state at low temperature in the freeze-drying machine equipment. After the center temperature of the material reaches the freezing temperature, a pre vacuum is applied. After the vacuum value of the box reaches the required level, a drying stage is carried out. At this time, the electronic control system controls the heating rate of the partition to perform sublimation drying of the flowing water. After the first drying stage is completed, the analytical drying stage is carried out, which is to dry about 10% of the bound water. After the three stages of operation of the freeze-drying machine, the diagnostic reagent freeze-dried product with a water content of less than 1% needs to be obtained. The entire operation process is controlled by PLC electrical control according to the set process program, including the refrigeration system, vacuum system, heating system, and circulation system. The temperature, vacuum degree, and operating time are precisely controlled during the operation of the freeze-drying machine, ensuringdiagnostic reagentThe effect of vacuum freeze-drying.

utilizediagnostic reagentThe working principle of freeze-drying machine is widely used in the freeze-drying treatment of diagnostic reagents, detection reagents and other biological reagents, ensuring that they are dried under sterile conditions, stable operation of sublimation drying, and basic maintenance of the activity and nutritional components of dried materials.
