Laboratory equipment vacuum drying oven price
The vacuum drying oven can maintain a certain degree of vacuum in the working chamber and use an intelligent digital temperature regulator to set, display and control the temperature. The temperature regulator adopts computer technology to collect and process the temperature signal in the working room, so that the temperature in the working room can be automatically maintained at a constant temperature. The temperature control system belongs to P.I.D intelligent temperature control, reliable performance and easy to use.
Advantages of vacuum drying oven:
1. The vacuum environment greatly reduces the boiling point of the liquid that needs to be evaporated, so vacuum drying can be easily applied to heat-sensitive materials;
2. For samples that are not easy to dry, such as powder or other granular samples, the vacuum drying method can effectively shorten the drying time;
3. Various mechanical parts with complex structures or other porous samples are cleaned and then vacuum-dried, leaving no residual material after being completely dried;
4. It is safer to use. Under vacuum or inert conditions, the possibility of oxides exploding when exposed to heat is completely eliminated;
5. Compared with ordinary drying that relies on air circulation, powdered samples will not be blown or moved by flowing air.
Operation process of vacuum drying oven
1. Put the materials evenly on the sample rack in the vacuum drying box, and put it into the drying box
2. Close the door of the box tightly, the air release valve, and there are bolts on the door, which can make the box door and the silicone sealing strip tightly combined
3. Connect the vacuum pump to the vacuum valve, open the vacuum valve, and vacuum
4. According to the performance of the vacuum pump, the limit value of the vacuum pump to the pressure gauge shall prevail
5. After vacuuming, close the vacuum valve first. If the vacuum valve does not close tightly, please replace it, and then turn off the vacuum pump power supply. (Prevent suction phenomenon)
6. During the drying process, observe the pressure gauge, temperature gauge, and the changes in the box at regular intervals. If the pressure gauge index drops, there may be air leakage, and you can perform air extraction again.
7. After the drying is completed, first open the air release valve to release the gas inside, and then open the door of the vacuum drying box to take out the material
