Vacuum drying ovens are widely used in research applications such as biochemistry, chemical pharmacy, medical and health, agricultural research, environmental protection, etc., for powder drying, baking, and disinfection and sterilization of various glass containers. It is especially suitable for fast and efficient drying treatment of dry heat sensitive, easily decomposed, easily oxidized substances and complex composition items.
1. This vacuum drying oven adopts independent partition heating, multi-segment PID full temperature range on the touch screen, program temperature control, accurate and reliable temperature control, uniform and stable heating.
2. Bullet-proof tempered glass observation window, the objects inside are clear at a glance when working, and inert gas can be rushed into the inside.
3. The closing tightness of the box door can be adjusted, and the synthetic silicon door sealing ring is integrally shaped to ensure high vacuum in the box.
4. Storage, heating, testing, and drying can be carried out in an environment without oxygen or full of inert gas, and will not cause oxidation.
5. The heating method is flexible and changeable. Single-layer or double-layer heating mode can be selected.
6. The controller can choose two operating modes: fixed value or program
7. The heating rate can be set during constant value operation, and three modes of start timing, constant temperature timing and shutdown timing can be selected.
8. When the program is running, 30 sections of programs can be set, and each program corresponds to 40 steps. The corresponding numbered program can be called according to different test requirements.
9. In each program, the temperature, time and jump of each step can be flexibly set, and a certain section can be inserted or deleted at will, which is convenient for changing the program.
10. There are hold and skip buttons in the main interface of program operation, which can hold in a certain section or jump to the next section to run.
11. Real-time temperature curve recording, which is convenient for users to visually see the heating process
12. The instrument has a built-in intelligent temperature control algorithm, which can ensure accurate temperature control in any temperature section, ensure zero overshoot, and built-in multi-layer password protection to prevent users from changing internal parameters due to mis-operation
13. The screen can be always on, and the screen can be turned off manually or automatically. When the screen is off, the corresponding status indicator will automatically light up, which is convenient for understanding the operating status of the instrument.
