A laboratory sink is a basin installed in science laboratories for washing glassware, cleaning equipment, and disposing of liquid waste. It is an essential component of lab furniture used in chemistry, biology, and physics laboratories. Laboratory sinks are usually made from chemical-resistant materials such as polypropylene (PP), ceramic, stainless steel, or epoxy resin to withstand acids, alkalis, and other chemicals. The sink is connected to a water supply tap and drainage system for proper washing and waste disposal. These sinks are commonly fitted on lab working tables or island tables and may include drain boards, bottle traps, and water taps for easy use by students and researchers.
