Kyushu space explains the working principle of vacuum drying oven

Designed for drying heat-sensitive, easily decomposable and easily oxidizable materials, the vacuum oven can be filled with inert gas, especially for complex ingredients. This product has the following characteristics:

1. The rectangular parallelepiped studio maximizes the effective volume, and the microcomputer temperature controller is accurate and reliable in temperature control.

2, tempered, bullet-proof double-glazed doors to observe the objects in the work room, at a glance.

3, the box closure elastic can be adjusted, the overall molding of the silicone rubber door seal ring, to ensure high vacuum inside the box.

4. The studio is made of stainless steel (or wire drawing) to ensure the durability of the product.

5. Storage, heating, testing and drying are carried out in the absence of oxygen or in an inert atmosphere, so it will not oxidize.

6, the shortest heating time, compared with the traditional vacuum drying box than the heating time reduced by more than 50%.

The drying oven is a large-volume container that can be set to keep the temperature constant and dry the wet glassware. The temperature inside the oven can be set using the control knob on the front panel. The actual temperature can be read directly by the thermometer attached to it. Because the boiling point of water is one hundred degrees Celsius, the temperature of a Baidu will make the glassware dry quickly.

However, at temperatures above 80 degrees, the vapor pressure of the water is quite large, which allows the wet vessels to dry quickly. Moreover, even in the experiments for quantitative analysis, all the dried vessels should be used at room temperature, so the time required for the vessels with too high temperature to return to room temperature will be lengthened; therefore, the use of the drying oven The temperature does not have to be set above the boiling point of water. The drying oven can also be used for drying chemicals. If the small molecules adsorbed on the surface of the compound are to be excluded, the temperature of the drying oven must be set to be above 120 degrees Celsius for two hours to make the water The molecule is driven away so that the true weight of the object can be measured.
