lab

Lab is an abbreviation for laboratory, a controlled environment where scientists conduct experiments, collect data, and analyze materials. Laboratories operate across sectors such as academia, industry, healthcare, and government, and may focus on chemistry, biology, physics, medicine, or engineering.

Common laboratory types include research labs, clinical laboratories, diagnostic laboratories, and industrial or quality-control labs. They rely on standardized procedures, calibrated instruments, and safety systems to ensure reliable results and worker protection.

Facilities typically feature workbenches, ventilation, safety equipment, and instrumentation such as microscopes, spectrometers, chromatography systems, and computer workstations for data analysis. Procedures emphasize documentation, reproducibility, validation, and compliance with regulatory standards.

Laboratories handle hazardous materials and may require biosafety levels or chemical hygiene plans. Waste disposal, waste segregation, and incident reporting are integral to operations.

Lab is also a common shorthand for the Labrador Retriever, a medium-to-large sporting dog breed developed in Newfoundland and Labrador. Known for friendliness, intelligence, and versatility, Labradors are widely used as family pets, service dogs, and working dogs.
