Usage of vacuum drying oven and electric heating oven

The vacuum drying oven is specially designed for drying heat sensitive, easy to decompose and easy to oxidize substances It can be filled with inert gas, especially for some complex components The product has the following features: 1 Cuboid studio, making the effective volume reach Zui, microcomputer temperature controller, reliable temperature control 2 The toughened and bulletproof double-layer glass door can be used to observe the objects in the studio at a glance 3 The closure tightness of the box can be adjusted, and the overall shaped silicone rubber door seal ring ensures high vacuum in the box 4 The workroom is made of stainless steel plate (or wire drawing plate) to ensure the durability of the product 5 Storage, heating, test and drying are all carried out in an environment without oxygen or full of inert gas, so they will not be oxidized 6 The heating time of Zui is shorter than that of traditional vacuum drying oven by more than 50% The oven is a large volume container that can be set to keep the temperature constant and dry the wet glassware The temperature in the oven can be set with 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 centigrade, the temperature of one can make glassware dry quickly But when the temperature is more than 80 ℃, the vapor pressure of water is quite large, which can make the wet vessels dry quickly Moreover, even in the experiment of quantitative analysis, all dried vessels should be used at room temperature, so the time required for the vessels with too high temperature to recover to room temperature will be prolonged; therefore, the use temperature of the oven does not have to be set above the boiling point of water The oven can also be used to dry chemicals If the small molecules adsorbed on the surface of the compound are to be excluded, the temperature of the oven must be set at 120 ℃ for two hours, which is enough to drive away the water molecules In this way, the real weight of the substance can be measured Because the oven is powered by electricity to provide heat energy, and the wet goods can conduct electricity, so it is advisable to be careful not to have leakage phenomenon in use, so generally, the oven should be grounded for use to ensure safety If there is no ground wire, make sure that there is no leakage in the oven; if there is slight leakage, try to pull out the socket and insert the pin in the opposite direction If there is no leakage, use it carefully If there is still leakage, stop using it immediately.
