What is a Dropper? Types and Uses of this Versatile Laboratory Tool

A dropper is a tool used to transfer a small amount of liquid from one container to another. It has a long, thin tube with a small opening at the end that is inserted into the source container and a larger opening at the other end that is inserted into the destination container. The liquid is drawn up into the tube by capillary action or suction, and then released into the destination container.

Droppers are commonly used in laboratory settings to transfer small amounts of liquids, such as reagents or samples, from one container to another. They are also used in medical settings to administer medications or other substances to patients.

Some common types of droppers include:

* Pipette droppers: These are the most common type of dropper and have a long, thin tube with a bulb at the end that is squeezed to draw up the liquid.
* Pinch droppers: These have a small opening at the end of the tube that is pinched shut to draw up the liquid.
* Syringe droppers: These are similar to pipette droppers but have a hollow needle instead of a bulb.
* Automatic droppers: These are electronic devices that automatically dispense a set amount of liquid when a button is pressed.
