Laboratory Freeze Dryer

Laboratory freeze dryer is widely used in medicine, pharmaceutical, biological research, chemical and food. The lyophilized articles are easy to store for a long time, and can be restored to the state before lyophilization and maintain the original biochemical characteristics after adding water. Lab freeze dryer has many types to meet different request, such as bell type, top-press type, manifold type, T type etc, customer can choose suitable one as request.

  • Selection Of Laboratory Freeze Dryers
    Freeze drying is a process in which water-containing substances are first frozen into a solid state; the water is then sublimated from solid to gas under a vacuum to remove moisture and preserve the material. Products obtained through this method retain their original chemical and biological properties, are easy to store long-term, and can return to their pre-freeze-dried state upon rehydration while maintaining their original biochemical characteristics; it is considered an excellent drying method.
  • What about the refrigerant leak in the laboratory freeze dryer?
    Refrigerant, also known as refrigerant, is commonly known as snow in some areas of the South. It is a working substance that continuously circulates in a refrigeration system and undergoes its own state change to achieve refrigeration. The refrigerant absorbs heat in the evaporator by heat of a cooling medium (water or air, etc.), and transfers heat to the surrounding air or water in the condenser to condense.
  • Advantages of freeze drying technology for laboratory freeze dryers
    Drying methods are various, such as drying, boiling, drying, spray drying, and vacuum drying, but ordinary drying methods are usually carried out at temperatures above 0 ° C or higher. The products obtained by drying generally have problems of shrinking size and hardening of the texture. Most of the volatile components are lost, some heat-sensitive substances are denatured and deactivated, and some substances are even oxidized. Therefore, the dried product has a large difference in properties compared with that before drying. The freeze drying technology of the laboratory freeze dryer has the following advantages over the advantages of ordinary drying technology:
