1) The gripping method is to hold the glass tube with the middle finger and ring finger to maintain stability, and to control the inhalation or drip dosage of the reagent by squeezing the rubber head with the thumb finger and index finger
2) When adding liquid, the rubber head dropper should not extend into the container, let alone touch the container
3) It should not be placed upside down or flat on the table. It should be inserted into a clean bottle or test tube
4) After use, wash with water immediately. It is forbidden to suck another reagent without cleaning
5) The rubber cap and glass dropper should be tightly combined without air leakage. If the rubber cap is aged, it should be replaced in time
One of the most error prone is to put the rubber head dropper under the tube mouth. In addition, it should be noted that the rubber head dropper should be kept upright when dropping reagent into the tube
