LGJ-18S Plate Layer Heating Vacuum Freeze Drying Machine Electrochemical Frost Matching Pump

LGJ-18S Plate Layer Heating Vacuum Freeze Drying Machine Electrochemical Frost Matching PumpDetailed introduction:

LGJ-18S (electric heating) ordinary vacuum freeze dryer, freeze-drying area: 0.18 ㎡/0.27 ㎡, cold trap temperature is -60 ℃, customizable -85 ℃ cold trap, cold trap has pre freezing function. Widely used in fields such as pharmaceuticals, biological research, chemical engineering, and food. Items that have undergone freeze-drying treatment are easy to store for a long time, and can be restored to their pre freeze-drying state and maintain their original biochemical characteristics after adding water. LGJ-18S (Electric Heating) Vacuum Freeze Drying Machine is a small vertical freeze drying equipment with shelf heating and programmable functions, suitable for laboratory use or small-scale production, and can meet the requirements of most laboratory routine freeze drying. The starting temperature of the vacuum pump can be preset. When it is lower than the set temperature, the vacuum pump can be started effectively to prevent a large amount of water vapor from entering the pump; Extend the service life of vacuum pumps. The intelligent data recording system automatically saves freeze-drying data, continuously records real-time data to generate tables, and can be viewed in the form of real-time curves and historical curves, making the entire freeze-drying process clear and concise.

The main applications of LGJ-18S (electric heating) ordinary vacuum freeze dryer are:

Suitable for freeze-drying of bulk (liquid, paste, solid) conventional substances. Effectively suppressing the biological, chemical, or physical changes of thermosensitive substances, and effectively preserving the active substances in the raw materials, as well as maintaining the color of the raw materials. Vacuum freeze dryers are applied in fields such as life sciences, biopharmaceuticals, biological products, and university research laboratories. They can freeze dry proteins, peptides, colloidal gold, biological products, enzyme products, solutions, solid materials, etc. After freeze-drying, the sample can maintain its original biological characteristics, retain its activity without loss, and can be stored for a long time, making it convenient for transportation. The freeze-dried material can be stored for a long time, maintaining a stable biochemical structure and activity. It can quickly recover to its original state after adding water and has good rehydration properties.
