A List of Chemistry Laboratory Apparatus and Their Uses • Safety goggles and safety equipment. • Beakers. • Erlenmeyer flasks, AKA conical flasks. • Florence flasks, AKA boiling flasks. • Test tubes, tongs, and racks. • Watch glasses. • Crucibles. • Funnels. • 1. Microscope: • A microscope is a very basic and needful equipment of biology laboratory. A simple light microscope (compound microscope) is the one, which is mostly used in schools and colleges and it uses natural 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: • The next very common apparatus are the test tubes. 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. • Beakers are another cylindrical utensil made up of glass, with a flat bottom and the upper opening having a spout. They are of varying sizes and are used to hold, heat, or mix substances with the proper measure. • 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. • This is one of the most important equipment of any lab, which is made up of glass and is calibrated to hold a precise volume of liquids at any precise temperature. Different sizes of volumetric flasks are available, each calibrated for exact measurement of liquids and solutions. In chemistry labs, it is mostly used in the preparation of standard solutions. • Bunsen burner This apparatus produces a single open flame and it is used for heating and sterilization purposes in the various experiments conducted in labs. • The dropper, also known as Pasteur pipette, is a common small apparatus, usually made up of plastic or glass cylinder, having a small nozzle on one side and a rubber holder on the other. It is used to put the liquids or solutions in any medium dropwise, that is, one drop at a time, a piece of necessary equipment when any reagent is required in an extremely small amount in a solution. • Every lab is equipped with a basic thermometer as many times, certain chemical or biological reactions can be carried out in any particular temperature range only and so to proceed, the thermometer becomes very necessary to measure the temperature of the required solution before moving forward with further reaction procedure. • Tongs, though not much in use, are common and basic apparatus in any lab. They are used to grasp and lift hot vessels and harmful substances during any kind of reaction taking place in the lab. • Brushes serve as the cleansing apparatus of the test tubes, as they are the only things that can get fit into the narrow-mouthed test tubes and other cylindrical and narrow objects. • When we perform experiments in the laboratories, we deal with very small quantities of reagents usually in the units of micro or mini grams. With a general physical balance, it is tough to get the desired and exact amounts of the reagents and so these weighing machines come in the picture. These machines help in measuring very small units of substances in terms of weight. • The wash bottles are laboratory consumables used for cleansing and sterilization purposes. These bottles are made up of plastic, which serves as a squeezy container with a long nozzle. They mostly contain distilled water, ethanol or deionized water. • These laboratory spatulas are very much similar to the kitchen like spatulas found in our home but they are just very smaller in size in comparison. The spatulas are usually resistant to heat and acids, hence making them suitable for large range use in the laboratory experiments. • Spring balance also referred to as Newton meter, is another instrument helpful in measuring the weight of an object. This apparatus consists of a spring and a hook and it works on the principle of Hooke’s law, according to which, the force applied to an object is directly proportional to the extension, provided that the elastic limit is not reached. • Holy Name University: • https://www.hnu.edu.ph/beta/ • https://www.hnu.edu.ph/beta/index.php... • https://www.hnu.edu.ph/beta/index.php... • https://www.hnu.edu.ph/beta/index.php... • https://www.hnu.edu.ph/beta/index.php...
