An Analytical Balance is a highly sensitive laboratory instrument designed to measure the mass of substances with extreme accuracy. It is a Class II balance often referred to as a laboratory balance, capable of measuring solid, liquid, granular substances, or powders.

A colony counter is a device used to count bacterial, fungal, or other microorganism colonies that grow on solid culture plates. It is widely used in microbiology, food industries, pharmaceuticals, environmental labs, and clinical diagnostics.
Descriptive studies are types of research that focuses on describing the distribution of disease, health conditions, or other characteristics in a population.
Biological Safety Cabinets (BSCs), also called biosafety cabinets or microbiological safety cabinets, are enclosed ventilated laboratory workspaces designed to protect personnel, samples, and the environment from biohazardous materials.
A laboratory water bath is one of the most essential and commonly used instruments in biology, chemistry, medical, and industrial laboratories. It is primarily used for incubating samples at a constant temperature over a long period of time.
A vortex mixer (also called vortexer) is a small, simple, yet very useful laboratory device designed for mixing liquids quickly and efficiently. It works by creating a vortex (whirlpool-like motion) in the liquid, which ensures thorough mixing of contents.
A homogenizer is a very important laboratory and industrial instrument used for preparing uniform mixtures and suspensions. The term “homogenize” literally means “to make the same throughout.” In science, technology, and industries, many processes require samples to be broken down, mixed, or dispersed in such a way that every portion of the mixture has the same composition.
A colorimeter is a laboratory instrument used in colorimetry to measure how much light a solution absorbs or transmits. It helps determine the concentration of colored compounds in a solution by comparing it with a standard reference solution.
An ultracentrifuge is a highly advanced centrifuge that operates at extremely high speeds (60,000–150,000 rpm). It is used to separate very small biological and chemical molecules that cannot be separated by regular centrifuges.
