Laboratory techniques are methods used by scientists to conduct experiments and analyze samples. These techniques can include microscopy, which allows for the observation of small structures, and chromatography, used to separate mixtures into their individual components. Other common techniques are titration for measuring concentrations and spectroscopy for identifying substances based on their interaction with light. Proper use of laboratory techniques is essential for obtaining accurate and reliable results. Safety protocols, such as wearing personal protective equipment (PPE) and following chemical handling guidelines, are crucial to protect researchers and maintain a safe working environment. Mastery of these techniques is fundamental in fields like biology, chemistry, and medicine.
