But in most cases what you will see are the above kind of test tube which is most widely used. Test tubes come in various sizes and shapes, including plastic tubes used in medical labs. Test tubes are one of the most important apparatus as they are functional from storing to mixing reagents in any chemical or biological reactions. They come in different sizes but the most common standard size is 18*150 mm. They are usually cylindrical pipes made up of glass, with a circular opening on one side and a rounded bottom on the other side. The next very common apparatus is the test tube. The oculus stays close to the eye and enlarges the previous image even further, and we see that. The objective stays very close to the sample to be seen and makes a virtual large image of it. There are generally two lenses - objective and oculus. Below is the schematic diagram of a compound microscope with details of its parts:Ī microscope operates on the principles of refraction of light, and takes advantage of how convex lenses bend light. A simple light microscope (compound microscope) is the one, which is mostly used in schools and colleges and it uses natural or artificial light and a series of magnifying lenses to observe a tiny specimen. Microscope:Ī microscope is a very basic and needed equipment in the biology laboratory. Let us learn about the 20 common lab apparatus that you will see in the school science laboratory and their uses. Here is the detail guide about Lab Equipment Package designed for 40 students as per school board curriculum and get school affiliation easily (CBSE/ICSE/Others). All of these apparatuses are the pillars of every lab, be it in schools, colleges, research labs, or medical laboratories. Between standard 5 to 8, students get the knowledge of the basic lab apparatus and get to know about their uses. For every student, one of the common excitements of the school days remains associated with the discovery and introduction with the laboratory equipment in school labs.
