Direct answer:Product Application: Vacuum freeze dryers are widely used in the fields of medicine, pharmaceuticals, biological research, chemical engineering, and food. Items processed by freeze-drying are easy to preserve for the long term; after adding water, they can be restored to their pre-freeze-drying state and retain their original biochemical characteristics. The LGJ-10N series benchtop freeze dryer is suitable for laboratory use or small-scale production and can meet the routine freeze-drying requirements of most laboratories. Main Features: ● This machine adopts an imported-brand Secop compressor for refrigeration, with stable performance and rapid cooling, low cold trap temperature, and strong water capture capacity. ● The cold trap has a large opening and is made of corrosion-resistant 304 stainless steel material, meeting GLP requirements; it has a pre-freezing function for samples in the early stage, eliminating the need for an ultra-low temperature freezer or liquid nitrogen treatment.

Main Features:
●This machine adopts an imported-brand Secop compressor for refrigeration, with stable performance and rapid cooling, low cold trap temperature, and strong water capture capacity.
● The cold trap has a large opening and is made of corrosion-resistant 304 stainless steel material, meeting GLPrequirements; it has a pre-freezing function for samples in the early stage, eliminating the need for an ultra-low temperature freezer or liquid nitrogen treatment.
● Adopts a 7-inch true-color LCD touch screen control system, with simple and convenient operation and full functions. As a human-machine interface, it supports Chinese (English) switchable interface. The system is equipped with various sensors to display working time, cold trap temperature, sample temperature, and vacuum degree in the form of curves and numbers, and records drying curves and data;
● Industrial embedded operating system, with fast operation response speed and large data storage capacity; stored as EXCEL files, capable of storing large amounts of measurement data, and equipped with a USB communication interface. Experimental data can be extracted from a USB flash drive with one click and browsed and printed via computer.
● 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 intuitive.
● The vacuum pump start-up temperature can be preset; startup of the vacuum pump is effective when the temperature is below the set temperature, preventing a large amount of water vapor from entering the pump and extending the service life of the vacuum pump.
● Equipped with compressor secondary startup delay protection.
● The drying chamber adopts a colorless transparent one-piece injection-molded polycarbonate drying chamber, which is corrosion-resistant, not easily broken, without adhesive bonding, highly transparent, strongly sealed, and allows samples to be clearly and intuitively observed, enabling observation of the entire freeze-drying process.
● Equipped with a cold trap electric heating defrosting function, shortening the waiting time for secondary use.
● The connection between the vacuum pump and the main unit adopts an international standard KF quick connector, which is simple and reliable.
● All-stainless-steel water drain and gas charging valve, safe, corrosion-resistant, and leak-free.
●User passwords can be set for permission-based use and operation management.。
Optional accessory functions and parts (charged separately):
●Optional imported-brand vacuum pump;
● Optional vacuum differential pressure valve to prevent vacuum pump oil mist from rebounding and contaminating materials after a power outage;
●Optional vacuum pump mist filter to prevent indoor air pollution;
●Optional automatic gas backfill and drainage system；
● Optional water-vapor-resistant and organic-solvent-resistant vacuum pump
●Non-standard customization available；
