  1. Microscopes:

A microscope is a very basic and needed equipment in the biology laboratory. 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. Below is the schematic diagram of a compound microscope with details of its parts:


A microscope operates on the principles of refraction of light, and takes advantage of how convex lenses bend light.  There are generally two lenses - objective and oculus. The objective stays very close to the sample to be seen and makes a virtual large image of it. The oculus stays close to the eye and enlarges the previous image even further, and we see that more ...


  1. Test tubes:

The next very common apparatus is the test tube. They are usually cylindrical pipes made up of glass, with a circular opening on one side and a rounded bottom on the other side. They come in different sizes but the most common standard size is 18*150 mm. Test tubes are one of the most important apparatus as they are functional from storing to mixing reagents in any chemical or biological reactions.

Test tubes come in various sizes and shapes, including plastic tubes used in medical labs. But in most cases what you will see are the above kind of test tube which is most widely used. You may also get to see sample collection tubes if you're giving blood for some pathological examination more..


  1. Beakers:

Beakers are another cylindrical utensil made up of glass, with a flat bottom and an upper opening, which may or may not have a spout. They are of varying sizes and are used to hold, heat, or mix substances with the proper measure. Beakers come in every size from tiny 20 ml cups to liter-sized buckets, and everything in between - but 250-500 ml beakers are most common.



Beakers are very much favored in labs because of their ease of use. With the flat bottom and straight sides, they are very stable on most surfaces and best for boiling stuff safely; and with the large opening, you can pour things in or out of it, or stir the contents. However, that large opening also makes it unsuitable for storage purposes - use flasks for that more...



  1. Magnifying glass:

A magnifying glass is one of the first introduced lab equipment among the students. As the name suggests, it is used to view enlarged or magnified images of objects or read the small calibrations marked on many equipments. It has a convex lens for object enlargement and usually has a wooden handle to hold it.

A magnifying glass works with the principle of virtual image creation due to the refraction of light. The centerpiece of a magnifying glass is a convex lens (a round slab of glass fat in the center and progressively slender towards the edges). When light passes through it, a larger-than-life image of the objective is created behind it, which we see from the other side of the glass. The wooden or plastic handle, attached to the lens with a metal or plastic rim, helps you to hold the magnifying glass steadily more..
