1. Keep the two steps of each sample to be too different, so you should consider using a row of guns if you have the conditions.
2. If there are air bubbles in the gun, you should quickly blow the gun and discharge the air bubbles.
3. There are bubbles in the board. You can consider sucking it out with an empty gun, but be careful not to touch the bottom plate!
4. Try to use a gun, make notes, do it once, and avoid making standards next time.
5. After adding the coloring liquid, put it into a drawer that can be pushed and pulled, you can avoid the light and oscillate.
Operational attention:
1. When sucking the sample, the sample gun tip should not adhere to the excess liquid; when adding the sample, do not add liquid to the hole at 90 degrees, which will cause the liquid to remain on the tip, and the sample loading is not accurate.
2. Do not put the tip into the hole. On the one hand, if the bottom of the hole is contacted, the tip may be bent, and on the other hand, the liquid in the hole may be blown up, and the sample is not accurate.
