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.
Descriptive studies are types of research that focuses on describing the distribution of disease, health conditions, or other characteristics in a population.
UV-Vis Spectroscopy (Ultraviolet–Visible Spectroscopy) is a widely used analytical technique that studies how a sample absorbs or transmits ultraviolet (190–400 nm) and visible light (400–800 nm). It is also called absorption spectroscopy or reflectance spectroscopy.
Fluorimetry is an analytical technique used to measure the fluorescent light emitted by a substance when it absorbs ultraviolet (UV) or visible light. It helps in studying the concentration, properties, and interactions of compounds in a sample.
Hot Air Oven is a laboratory sterilization equipment based on dry heat. Learn its principle, parts, types, working steps, applications in microbiology, advantages, limitations, and safety precautions.
Learn the difference between null hypothesis and alternative hypothesis with definitions, symbols, examples, importance, and applications in biology research.
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) 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 (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).
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.
