LGJ-12S Capping Electric Heating Freeze Drying Machine Freeze Drying Curve with Pump

LGJ-12S Capping Electric Heating Freeze Drying Machine Freeze Drying Curve with PumpDetailed introduction:

The LGJ-12S (electric heating) capping type vacuum freeze dryer has shelf heating and programmable functions, 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 dryer to start freeze-drying operation according to the preset freeze-drying process. After freeze-drying is completed, the rubber stopper is pressed into the penicillin bottle through a pressure stopper device in a vacuum state to form a freeze-dried powder injection, which is equivalent to vacuum packaging and can avoid secondary pollution caused by contact with air. The cold trap has a pre freezing function, which can quickly pre freeze the sample and replace ultra-low temperature refrigerators. At the same time, it can capture the moisture sublimated from the sample. Standard configuration includes a domestically produced vacuum pump with high pumping speed, which can quickly achieve the required vacuum degree (1pa) of the equipment, shorten experimental preparation time, and improve overall freeze-drying efficiency; The connection between the vacuum pump and the host adopts the international standard KF quick connector. Suitable for laboratory use or small-scale production, it can meet the requirements of most laboratory routine freeze-drying.

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

Not only suitable for freeze-drying bulk (liquid, paste, solid) conventional substances, but also for drying penicillin bottled materials. When preparing for freeze-drying, the materials are divided into penicillin bottles as needed, and the bottle cap is covered before freeze-drying. After drying, the capping device is operated 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.

Manual capping (laboratory mini machine), the chamber maintains vacuum during capping, and the rubber stopper is pressed into the mouth of the penicillin bottle through a mechanical structure to complete sealing.

After freeze-drying, it can be sealed and stored at low temperature (or room temperature) for a long time, which is convenient for subsequent recovery or analysis.

For standard and reference materials, high purity and stability are required. Freeze drying under pressure can avoid component changes caused by contact between reagents and air, ensuring accurate analysis results.
