Let’s have a look at what can typically be found in a laboratory setup malaysia:
A microscope is an essential piece of equipment in any biology laboratory. A simple light microscope (compound microscope) is a type of microscope that is commonly used in schools and colleges. It uses natural or artificial illumination and a series of magnifying lenses to examine a relatively small sample.
The test tube is the next most common piece of equipment. They are typically cylindrical glass pipes with a circular opening on one corner and a rounded bottom on the other. They are available in a variety of sizes, but perhaps the most common standard size is 18*150 mm. Test tubes are one of the most essential apparatuses because they can be used to store and mix reactants in any biological or chemical reaction.
Beakers are another type of glass cylindrical utensil with a flat bottom and a top opening that may or may not have a spout. They come in a variety of size and shapes and are used to hold, heat, or combine materials in the proper proportion. Beakers range in size from tiny 20 mL cups to liter-sized buckets and everything in between – but the most common size is 250-500 mL beakers. Because of their simplicity, beakers are widely used in laboratories. They are very steady on most surfaces and best for boiling stuff safely because of the flat bottom and straight sides; and because of the large opening, you can pour matter in or out of it or stir the contents.
A magnifying glass was one of the first lab tools introduced to students. It is used to view oversized or magnified images of objects or to read the small readings marked on many pieces of equipment, as the name implies. It has a convex lens for enlarging objects and a wooden handle to carry it. A magnifying glass operates on the principle of virtual image formation due to light refraction. A convex lens is the focal point of a magnifying glass (a round slab of glass fat in the centre and progressively slender towards the edges). When light passes through it, it produces a wider image of the objective behind it that we can see from the other side of the glass.
This is one of the most vital pieces of laboratory equipment because it is made of glass and is fine-tuned to hold a specific amount of liquids at any fixed temperature. Volumetric flasks of various sizes are available, each calibrated for accurate measurements of liquids and solutions. It is mostly used in chemistry labs to prepare standard solutions. A volumetric flask has a big bulbous body at the bottom that can be flattened or round. The body has a long, narrow neck that is ideal for inserting a stopper.
The dropper, also known as a Pasteur pipette, is a common small instrument composed of a plastic or glass cylinder with a little nozzle on one side and a rubber holder on the other. It is used to drop liquids or solutions into any medium one drop at a time, making it a necessary appliance when any reactant is needed in an exceedingly minuscule quantity in a solution.
