Vacuum degassing box is a device widely used in chemical, pharmaceutical, food and other fields, mainly used to remove air bubbles and gases in liquids.
Selection points
1. Vacuum degree: The vacuum degree of the vacuum degassing box needs to be selected according to the experimental requirements, generally divided into low vacuum, medium vacuum, high vacuum and other levels.
2. Volume: It is necessary to select a suitable volume according to the experimental requirements. Generally, a suitable volume should be selected to avoid waste caused by too small or too large volume or the experiment cannot be carried out.
3. Material: The material of the vacuum defoaming box should have good corrosion resistance and stability, generally stainless steel or other corrosion-resistant materials.
4. Vacuum pump: The Vacuum Pump of the vacuum defoaming box needs to select the appropriate model and brand according to the experimental requirements to ensure its stable and reliable performance.
5. Control mode: The control mode of the vacuum defoaming box usually has two types: digital control and mechanical control. Digital control is more accurate and reliable, but the price is higher. It is necessary to choose an appropriate control mode according to the experimental requirements.
6. Safety: The vacuum defoaming box needs to have good safety performance, such as overvoltage protection, leakage protection and other safety functions.
Precautions
1. Before use, you need to check whether the equipment is in good condition, and confirm whether the Vacuum Pump, vacuum gauge, power cord, etc. are normal.
2. When using, it is necessary to operate according to the instructions to avoid equipment damage or experiment failure caused by excessive use or improper operation.
3. Avoid overloading during use to avoid damage or danger to the equipment.
4. The interior of the vacuum defoaming box should be placed neatly to avoid improper placement from affecting the experimental results.
5. When adjusting the vacuum degree, it needs to be adjusted gradually to avoid changing the vacuum degree too fast and affecting the experimental results.
6. The vacuum defoaming box needs to be kept dry during use to prevent moisture from entering the equipment and affecting the experimental results.
7. It is necessary to regularly check the safety of the vacuum degassing box, such as checking whether the sealing ring is intact, so as to ensure the normal operation and safe use of the equipment.
8. After the vacuum defoaming box is stopped for a long time, it is necessary to clean the inside in time and preheat it before re-use.
