When the liquid is sucked into the buffer cup, the user should stop continuous operation and close the vacuum pump. The main body of the buffer cup and the pump is connected by a thread similar to the mouth of a general beverage bottle. The buffer cup can be removed by only slight rotation, and the inhaled liquid can be poured out.
After cleaning the buffer cup, use a paper towel or dry it to completely dry it, you can unscrew the white filter element, also use a threaded connection, you can also use the same method to simply clean, use a paper towel to absorb the surface water, and then use a hair dryer to dry it completely . Then the filter element and buffer cup can be screwed back in their original position. When screwing back, pay attention to the thread position and tighten slowly to prevent the thread from becoming slippery.
If inhaling dust particles, clean the filter element and buffer cup, and dry the filter cup and filter element as described above. However, if it is a very fine particle, the filter element will completely fail after the adsorption reaches the limit. At this time, the filter element needs to be replaced, otherwise the vacuum degree and pumping speed of the instrument will decrease.
There are two points to pay attention to when using the buffer cup and filter element:
1. The water must be completely dried before reinstalling these accessories, otherwise the remaining water will still be sucked into the vacuum pump and damage the instrument.
2. They cannot be cleaned with cleaning agents, which may cause corrosion and cracking. Only ordinary detergent and water can be used.
