Gotero graduatuak beirazko edo plastikozko hodiaren gainean huts partzial bat sortuz funtzionatzen du. Hutsa askatuz gero, likidoa sartzen da edo banatzen du.
To use a graduated dropper, squeeze the bulb and hold the tip in the liquid. Be sure not to touch the bottom of the bottle. Release the bulb to draw the liquid into the dropper.
Squeeze the bulb to dispense the liquid.
