How to use the correct essence dropper?
But the general dropper is a rubber-tipped dropper, there are also places to pay attention to when using it: when sucking liquid: first squeeze the rubber tip with your thumb and index finger to drive out the air in the dropper, then stick the glass nozzle into the essence, release your thumb and index finger, the essence liquid will be inhaled, and then lift the dropper. Avoid squeezing the tip inside the liquid in order to avoid frequent air contamination of the test. After the liquid is sucked, the tip must be placed upwards, not flat, and not to make the opening of the glass tip upwards, so as not to corrode the tip; nor should the dropper be placed flat on the table after the liquid is sucked, so as not to stain the dropper.
What is the correct way to use different droppers?
The design principle of the small dropper is to use the pressure pump to extract and suck up the essence in the bottle. The method to use half of it and find that the essence cannot be sucked up is very simple, use the way of pressing to drain the air inside the dropper first.
If it is a squeeze type dropper, squeeze the dropper hard to put it back into the bottle, do not let go of the bottle to tighten the mouth;
If the dropper is a press-on dropper, press the dropper down completely when putting it back into the bottle to make sure the air is completely squeezed out. This way, the next time you use it, you only need to gently unscrew the bottle, no need to squeeze, and the essence will be enough for one use.
