The main principle of a vacuum freeze dryer is a low-temperature drying equipment that uses sublimation to dehydrate materials. It freezes the water-containing material into a solid, and under low-temperature and low-pressure conditions, utilizes the sublimation property of water to achieve low-temperature dehydration and drying of the material. This novel drying method is suitable for freeze-drying and strain preservation in fields such as biological research, medical pharmaceuticals, chemical engineering, food processing, and higher education institutions.

Main Features:

1. Desktop design, compact, Occupies minimal table space.

2. Attractive appearance, ergonomic design, and easy operation.

3. Imported fully enclosed compressor, efficient and reliable, with low noise.

4. Configure the cold trap sample pre-freezing function, eliminating the need for an ultra-low temperature freezer or liquid nitrogen treatment.

5. The cold trap is made entirely of stainless steel, with no coils inside, featuring a smooth and corrosion-resistant surface.

6. Design a draft tube to increase the effective area of the cold trap and achieve rapid freeze-drying.

7. Standard inflation valve is included, allowing for the inflation of dry nitrogen or inert gas.

8. Transparent bell jar drying chamber, safe and intuitive.

9. International standard vacuum interface, compatible with various vacuum pumps.

10. The digital display shows the temperature and vacuum level.

11. Sample temperature display and touchscreen display (Optional (available as an add-on))。
