How to Use a Dropper Bottle

Dropper bottles enable measurement by drops.

Dropper bottles are used in many fields, from cosmetics to medicine. The bottle is usually small and constructed of glass or plastic. The screw-on top contains a suction tube for dispensing liquids in small amounts or one drop at a time. Some tubes, especially those used for medicinal products, have measurements marked on them to aid you in releasing the correct amount.

Instructions

1. Unscrew the cap from the dropper bottle. Press the rubber bulb between your fingers to dispense any liquid already in the tube. Screw the cap back on and shake the bottle if necessary for the type of liquid you are dispensing.

2. Unscrew the cap again and squeeze the bulb while the tube is inside the bottle. This will draw the liquid up into the dropper tube. You may need to tilt the bottle if the liquid level is low. If using a measured amount, manipulate the bulb to get the liquid to the measurement mark indicated for your use. To release liquid from the dropper, press the bulb while the tube is not within the liquid.

3. Press the bulb briefly to release drops. Do this for each drop indicated for your purposes.
