Laboratory chemicals are substances used in scientific experiments, research, and testing within laboratories. They include a wide range of compounds such as acids, bases, salts, solvents, indicators, and reagents. These chemicals are essential for conducting experiments in chemistry, biology, physics, and medical labs. Each chemical has specific properties and must be handled according to safety guidelines. Some are harmless, while others can be toxic, flammable, or corrosive, so proper storage and usage are important. Laboratory chemicals are available in different grades depending on their purity, such as analytical grade, laboratory grade, and technical grade, based on the needs of the experiment. They play a vital role in education, industry, and scientific discovery.
