When you are considering purchasing a laboratory vacuum drying oven, You need to understand the advanced technology and important features. Laboratory vacuum drying ovens manufactured by Wewon Environmental Chambers Co., Ltd. use advanced electric heating technology and blower systems to ensure uniform temperature distribution, Thereby achieving efficient and precise drying results. We offer many types of laboratory vacuum drying ovens, including large, small and precision models, to suit every need.

Unlike other vacuum drying ovens, our vacuum drying oven adopts the operation steps of vacuuming first and then heating. Doing so has several benefits, not the least of which is that it avoids potential hazards in a laboratory environment while increasing the efficiency and longevity of the equipment. For example, If the workpiece is heated first, the tremendous pressure created by the expanding gases may cause the tempered glass of the viewing window to burst.

Moreover, Vacuuming first and then heating can avoid the heat being brought to the vacuum pump when the heated air is pumped out by the vacuum pump, causing the temperature to be too high. Additionally, With correct operating methods, you can extend the life of your vacuum drying oven.

We offer vacuum drying chambers equipped with vacuum pumps to ensure you have better pressure control while drying. Laboratory vacuum drying ovens are widely used in various fields, such as chemical laboratories, biomedicine, materials science, etc. Our vacuum drying ovens can be used to dry a variety of materials, prepare a variety of specimens and maintain the quality of items at specific temperatures.
