LGJ-12S electrochemical frost freeze dryer with programmable multi manifold cover

LGJ-12S electrochemical frost freeze dryer with programmable multi manifold coverDetailed introduction:

LGJ-12S (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. It has a cold trap pre freezing function and uses a LCD touch screen to display the freeze-drying operation status and freeze-drying curve, including sample temperature, cold trap temperature, vacuum degree, and other freeze-drying curves. Widely used in fields such as life sciences, biological products, biopharmaceuticals, cosmetics, nanomaterials, superhard materials, and nutritional foods. Suitable for vacuum freeze-drying of biological products, peptides, proteins, probiotics, cosmetics freeze-dried powder, EGF freeze-dried powder, repair freeze-dried powder, peptide freeze-dried powder, oligopeptide freeze-dried powder, whitening freeze-dried powder and other materials. It can also freeze dry graphene, diamond micro powder, etc. After freeze-drying, the sample can retain its original characteristics, complete its internal structure, and retain nutrients and activity without loss.

Multi manifold function: comes standard with 8 hanging bottles/freeze-drying bottles/eggplant shaped bottles, which can freeze dry 8 different materials simultaneously. The freeze-drying hood is equipped with 8 glue valves, each of which can hang a freeze-drying bottle. The vacuum state in the freeze-drying bottle can be controlled by controlling the switch of the glue valve. So after the freeze-drying bottle is rotated and frozen, it is directly hung on the glue valve, and the switch of the glue valve is opened to vacuum the sample in the freeze-drying bottle. 8 hanging bottles can be removed and hung at any time, improving the efficiency of freeze-drying.

Capping function: mainly used for freeze-drying liquid in penicillin bottles. Firstly, the liquid is filled into the penicillin bottle, and the rubber stopper of the penicillin bottle is covered (moisture sublimates through the gap of the rubber stopper and condenses into frost in the cold trap). It is then placed in the drying chamber of the freeze-drying machine to start freeze-drying according to the preset freeze-drying process. After freeze-drying is completed, the rubber stopper is compressed into the penicillin bottle under vacuum using a capping device to form freeze-dried powder injection, which is equivalent to vacuum packaging and can avoid secondary pollution caused by contact with air.

The main applications of LGJ-12S (electric heating) multi manifold pressure cover vacuum freeze dryer are:

On the basis of the characteristics of the ordinary type, it combines the features of the cover type and the multi manifold ordinary type.

Suitable for freeze-drying of bulk (liquid, paste, solid) conventional substances;

Suitable for drying penicillin bottled materials. When preparing for freeze-drying, divide the materials into penicillin bottles as needed, cover the bottle cap with a floating cap, and perform freeze-drying. After drying, operate the capping device to press the bottle cap tightly, which can avoid secondary pollution and re adsorption of moisture, and is easy to store for a long time;

Install a flask outside the drying chamber and dry the material frozen on the inner wall of the flask. At this time, the flask is connected to the manifold outside the drying oven as a container. The material in the flask is heated at room temperature and can be removed or added as needed through a multi manifold switch device without stopping the machine.

Vacuum freeze-drying technology is widely used in fields such as life sciences, biopharmaceuticals, biological products, and university research laboratories. This technology can be used for freeze-drying samples such as proteins, peptides, colloidal gold, biological products, enzyme products, solutions, solid materials, etc. Through freeze-drying treatment, the sample maintains its original biological characteristics and activity, is stored for a long time, and is convenient for transportation. This technology utilizes the principle of sublimation and operates in a low-temperature, vacuum environment. Firstly, the water in the frozen protein liquid is divided into ice crystals to enter a dormant state, and then sublimated in a vacuum environment to avoid oxidation reactions of internal molecules. The freeze-dried sample can be stored for a long time, quickly restored to its original state after adding water, and has good rehydration properties, maintaining a stable biochemical structure and activity.
