Laboratory procedures are systematic methods used to conduct experiments and analyze samples in a controlled environment. These procedures ensure accuracy, safety, and reproducibility of results. Common steps include preparing materials, following specific protocols, and using equipment like microscopes and centrifuges. Safety is a crucial aspect of laboratory procedures. Researchers must wear appropriate personal protective equipment (PPE), such as gloves and goggles, to minimize risks. Proper waste disposal and adherence to safety guidelines help prevent accidents and contamination, ensuring a safe working environment for all personnel involved in the research.
