What Is a Droppers Used For?
A droppers is a device that is used to transfer small amounts of liquid. They are frequently used in laboratories and to dispense small amounts of liquid medications. Dispensing eye drops into the eye was a very common use 1.
A dropper is made up of a long plastic or glass tube with an opening at one end and a rubber bulb on top. You can squeeze out the liquid you require by pressing this rubber bulb.
Droppers should not be used in laboratory work requiring high accuracy because they are not designed to measure specific volume; however, they can be used to add drops of reagents. Each dropper is designed to produce a specific drop volume, but this is not highly precise. Before using a dropper, the tip should be thoroughly examined for cracks. To improve accuracy, the pipette should be rinsed with reagent 3.
