Litmus And Filter Papers

These two cannot be called apparatus in a proper way, but they serve as one of the most important and basic things that will be required in any kind of laboratories. The litmus paper serves to identify the pH of any solution by changing colors whereas, the filter paper helps in the filtration process.
These are the basic apparatus that one can witness in any school or college biology labs. Other than these, one will also get to see wash bottles, stirring rods, stopwatch, weighing balance or brushes to clean test tubes. As these apparatuses serve the basic, every student must get familiar with all this equipment and their working to have safe and sound practical experiment experiences in High school biology laboratories.
