Here I have a dropper and a beaker. A beaker is a simple glass container that allows us to hold, stir, mix, and heat liquids. This little dropper is used to add very small amounts of liquid into a beaker or mixture.
Liquids in beakers can be heated on another piece of equipment called a Bunsen Burner. When you remove the beaker from the Bunsen Burner, you have to be extremely careful not to burn yourself. You will either use special gloves or tongs to remove a heated beaker.
Great point! This brings us to our last piece of equipment for today. Diego, will you present the microscope?
It's important to remember to always wear safety goggles when working around the Bunsen Burner. Heated liquids can boil or explode and damage your eyes. Lab safety is top priority.
This is how the dropper works. You lower it in a liquid and squeeze it then release to suck in some liquid. Next, you squeeze out one drop at a time.
Great question! You can use the dropper with several different types of lab equipment. You may use it with a graduated cylinder, and you may even use it to add a drop of liquid onto a microscope slide!
Do you only use the dropper with a beaker?
