1. A dropper is a glass container used to hold liquid reagents, typically used in laboratories or chemical experiments. The structure of a dropper: A dropper usually consists of a bottle body, a bottle neck, and a bottle mouth. The bottle body is cylindrical or conical in shape, with a thin neck for easy grip and tilting. The bottle usually has a funnel-shaped dropper at the mouth, which can control the number and speed of liquid drops.
2. The purpose of a dropper: The dropper is mainly used to hold small amounts of liquid reagents, such as acid, alkali, salt solutions, etc. It is one of the commonly used containers in laboratories due to its convenient access, easy cleaning, and resistance to contamination.
3. The capacity of a dropper: The capacity of a dropper is usually between tens of milliliters and hundreds of milliliters, and can be selected according to actual needs. In the laboratory, droppers of different specifications are generally used to store different reagents for easy classification and management.
4. Instructions for using a dropper: When using a dropper, first pour the reagent into the dropper, and then drip the liquid reagent into other containers as needed. When using, attention should be paid to controlling the number and speed of drops to avoid wasting reagents or splashing outside the container.
5. Storage and cleaning of droppers: droppers should be stored in a dry, cool place, away from direct sunlight. Ensure good container sealing during storage to prevent reagent evaporation or contamination. When cleaning the dropper, it should be rinsed with tap water first, then thoroughly cleaned with detergent and hot water, and finally rinsed with tap water and dried for later use.
