organic solventIt is a large class of organic compounds widely used in daily life and production，Modern technology is increasing the development and application of organic solvents.vacuum freeze dryer(abbreviated as freeze-drying)machine）Its working principleIt refers to freezing a substance containing water into a solid state first,after thatIn vacuumenvironmentBelow,supportThe water in it sublimates directly from solid to gas,reachThe method of preserving substances by removing moisture.Due to the special nature of organic solvents, laboratory freeze-drying machines are currently being used in major scientific and technological universities and enterprises for freeze-drying research and experimentation of organic solvents.

Organic solvents are a type of organic compoundThe characteristic is that it is liquid at room temperature and pressure, and has a largeevaporatesexuallyAnd corrosiveness，The crystallization point and eutectic point of solvents may vary depending on their concentration.according toThe requirements for the characteristics of organic solvents require the selection of ultra-low temperature laboratory freeze-drying machines. Normally, freeze-drying equipment with a temperature below -80 ℃ is required. At the same time, 304 or 316 stainless steel materials should be selected for laboratory freeze-drying machines based on material corrosion issues, especially for vacuum pumps. If conditions permit, dry pumps should be used to prevent damage to the vacuum pump.

Laboratory freeze dryerIn the research and experimentation of vacuum freeze-drying of organic solvents, ultra-low temperature control pre freezing and drying are required, and the heating rate of the drying process needs to be strictly controlled. The temperature of one freeze-drying should be controlled below the eutectic point of the material to ensure smooth drying. When developing and experimenting with organic solvents in the laboratory, pay attention to the emission of vacuum pump gases, as some gases are harmful to human health.

Laboratory freeze-drying machinePreviously, it has been widely used in major universities and research laboratories to develop various organic solvent products using FD freeze-drying technology. At the same time, FD laboratory freeze-drying machines can be used for food freeze-drying experiments, drug freeze-drying experiments, industrial material freeze-drying experiments, traditional Chinese medicine material freeze-drying experiments, and various strain freeze-drying experiments.
