The rubber head dropper is divided into two parts, one is the upper rubber head, which is made of plastic and very elastic, and the other is made of glass, which is the first place where the liquid enters. The specification of rubber tipped dropper is expressed by the pipe length, which is usually 90 mm and 100 mm. Each drop of rubber tipped dropper is 0.05ml.

Before use, the holding method is to clamp the glass part with the middle finger and ring finger to maintain stability, and squeeze the rubber head with the thumb and index finger to control the inhalation or drip amount of reagent. Hold the rubber cap tightly with your hand so that the air in the rubber head dropper can run out, and then the liquid to be taken can have space to enter the dropper.

Then stand the rubber dropper upright so that the liquid to be extracted can be easily absorbed into the test tube. Stand the dropper upright so that the liquid can be extracted better.

Then put the dropper into the liquid. Be careful not to put the whole dropper into the liquid. Just put half of the glass part into the liquid, because the whole dropper is useless. Try not to pollute the original liquid.

Then loosen the tightly held rubber cap so that the solution in the bottle can enter the test tube, so that the liquid can be easily extracted, so that our goal is achieved.

Take out the rubber dropper from the liquid. At this time, the liquid has entered the test tube. At this time, just take out the rubber dropper and move it to the liquid container to be placed. Just pinch the rubber head.
