Bioreactor – Principle, Design, Parts, Types, Applications, and Limitations

Bioreactor – Principle, Design, Parts, Types, Applications, and Limitations

A bioreactor is a specialized vessel used for biological reactions and fermentation processes. It provides a controlled environment where microorganisms, plant cells, or animal cells can grow and produce useful products like antibiotics, enzymes, organic acids, and biofuels.

High-Performance Liquid Chromatography (HPLC) – Principle, Instrumentation, Types & Applications

High-Performance Liquid Chromatography (HPLC) – Principle, Instrumentation, Types & Applications

High-Performance Liquid Chromatography (HPLC) is one of the most powerful and widely used techniques in modern laboratories. It helps to separate, identify, and quantify different components of a mixture with high accuracy and efficiency.

Mass Spectrometry – Principle, Steps, Instrumentation, Types & Applications

Mass Spectrometry – Principle, Steps, Instrumentation, Types & Applications

Mass Spectrometry (MS) is a highly precise analytical technique used to identify and measure the amount of chemicals present in a sample. It works by ionizing molecules and separating them based on their mass-to-charge ratio (m/z).

Centrifugal Force and Centripetal Force – Definition, Differences, Principles, Examples & Applications

Centrifugal Force and Centripetal Force – Definition, Differences, Principles, Examples & Applications

When an object moves in a circular path, two important forces come into play — centripetal force and centrifugal force. Centripetal force is a real force that pulls an object towards the center of its circular path. Centrifugal force is a fictitious (pseudo) force that seems to push an object outward, away from the center.
