Introduction to the use of rotary cap drip bottles by card box manufacturers and precautions

When using a dropper, pinch the rubber nipple with your fingers to expel the air from the dropper, then insert the dropper into the reagent bottle, release your fingers, and the reagent will be sucked in.

When adding liquid, it should be suspended above the beaker and not in contact with the beaker wall to avoid contaminating the dropper or causing contamination of the reagent.

4. Do not place the dropper on the test bench or other places to avoid contaminating the dropper.

5. Used droppers should be immediately rinsed with clean water for reuse.
