Why choose freeze drying

traditional drying will cause material shrinkage and destroy cells. The structure of the sample will not be damaged in the process of freeze-drying, because the solid components are supported by the solid ice on its seat. When the ice sublimates, he will leave a gap that will reduce the average price of the product by nearly two-thirds in the dry residual material. In this way, the biological and chemical structure of the product and the integrity of its activity are preserved

in the laboratory, freeze-drying has many different uses. He knows in many raw plastic manufacturers that plastic is based on resin, which is indispensable in chemical and pharmaceutical applications. It is used to obtain biological materials that can be preserved for a long time, such as microbial culture, enzymes, blood and drugs. In addition to the stability of long-term preservation, it also retains its inherent biological activity and structure. Therefore, freeze-drying is used to prepare tissue samples for structural research (such as electron microscope research). Freeze-drying is also used in chemical analysis. It can get the key points of sample preparation in dry state: test materials such as metal rods, sheet metal and plastics need to thicken the two ends of the sample, or concentrate the sample to increase the sensitivity of chemical analysis. Freeze drying makes the composition of the sample stable, and the energy used accounts for about 12% of the total energy consumption of the national economy. There is no need to change the chemical composition. It is an ideal auxiliary means of analysis. (end)
