Analytical Balance – Definition, Principle, Parts, Types, Working, Applications, Advantages & Precautions
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.
Independent and Dependent Variables in Research Methodology – Definition, Examples, and Key Differences
Learn the difference between independent and dependent variables with definitions, examples, types, and FAQs. Easy guide for students and biology research.
Colony Counter – Definition, Principle, Types, Parts, Working, Applications, Advantages & Examples
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.
Gel Electrophoresis System – Definition, Principle, Apparatus, Types, Examples, Applications, Advantages & Limitations
Gel electrophoresis is mainly used to separate DNA, RNA, and proteins based on their size, charge, and shape. It is one of the cornerstones of molecular biology and biotechnology. Gel electrophoresis is like a molecular sieve that helps scientists “see” and separate biomolecules.
Descriptive Studies in Research Methodology – Types, Applications, Advantages, and Limitations
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) – Definition, Classes, Working, Applications, Advantages & Precautions
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.
Water Bath – Definition, Principle, Types, Parts, Working, Applications, Advantages, Limitations & Precautions
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.
Vortex Mixer – Definition, Principle, Parts, Types, Working, Applications, Advantages & Precautions
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.
Homogenizer – Principle, Parts, Types, Working, Procedure, Applications, Advantages & Limitations
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.
