Instrumentation refers to the collection of tools, devices, and techniques used to measure, analyze, and test biological systems.
In biology, this field is often called bioinstrumentation and is considered a branch of biomedical engineering. It focuses on combining engineering innovations with medical and biological research to improve the way we study and diagnose living systems.
From common laboratory equipment like centrifuges, autoclaves, and microscopes to advanced techniques such as chromatography and electrophoresis, instrumentation plays a crucial role in research and diagnostics. It helps scientists understand the working mechanisms of devices, their components, and how they can be applied in experiments.
Instrumentation is not limited to research labs. In modern agriculture, bio-instruments are used to monitor soil quality, measure plant growth, and track physiological activities such as carbon dioxide exchange and net photosynthesis rates.
In molecular biology, advanced tools like RT-PCR, blotting techniques, and biosensors are used for genetic testing, disease diagnosis, and DNA sequence comparison. These innovations make medical processes faster, more accurate, and highly reliable.
Other important techniques like spectroscopy and colorimetry have made it easier to measure solution concentrations and detect radioisotopes with precision.
As technology advances, bioinstrumentation continues to evolve, introducing new devices, faster methods, and more efficient diagnostic tools. This growth is making instrumentation an essential part of every biological field, from agriculture and environmental monitoring to biomedical research and healthcare diagnostics.

Pulsed Field Gel Electrophoresis (PFGE) is an advanced laboratory technique used to separate very large DNA molecules. Unlike standard gel electrophoresis, PFGE can separate DNA fragments greater than 50 kilobase pairs (kbp) up to several megabase pairs (Mb).
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.
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.
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.
