1. Before purchasing a vacuum drying oven, first roughly determine the industry in which the customer is located:
Generally divided into: chemical industry, electronics industry, pharmaceutical factory, biological industry, scientific research institutions
2. Determine the experimental temperature of the vacuum drying oven that the customer usually uses:
The temperature control range of a general vacuum drying oven is RT+10~200 ℃. In addition, some professional manufacturers will produce certain types of special boxes after understanding the needs of a certain industry, such as for biological In the industry, some customers require a temperature control range of RT+10~65 ℃, and Shanghai Yiheng Factory has produced a special vacuum drying oven for biology for such customers.
3. What kind of material do you want for the inner tank of the vacuum drying oven:
The vacuum drying oven is usually divided into cold-rolled plate and stainless steel according to different materials, and the stainless steel is subdivided into 304/316 stainless steel. Yiheng Factory recommends that if the experiment in the chemical field has a certain degree of corrosion, users can choose 316 stainless steel. , with better corrosion resistance.
4. Vacuum degree control method:
Vacuum degree control methods are usually divided into: manual control and automatic control, which refers to whether the vacuum pump is automatically re-evacuated or needs to be manually started when the object in the vacuum drying box is heated and evaporates to produce water vapor to affect the vacuum degree during the experiment. It goes without saying that the automatic control is more convenient. For the automatic control box, Yiheng’s model is the BPZ series digital display vacuum gauge. The price is relatively higher than that of the ordinary DZF vacuum drying box. user’s budget to purchase.
5. Heating method:
The heating methods of the vacuum drying oven include bundled heating around the inner tank and shelf heating. In terms of heating speed and temperature uniformity, we recommend using the shelf heating method, because the heated objects on each shelf can be heated More uniform, the disadvantage is that the shelf of this type of vacuum drying box cannot be disassembled, and the vacuum drying box with bundled heating method can be disassembled by itself, and you can choose according to your own needs.
6. The size, volume and footprint of the vacuum drying oven.
