A laboratory plastic wash bottle is a durable, squeezable container used for dispensing and rinsing liquids, typically in laboratory settings. Made from low-density polyethylene or similar plastic, it features a narrow, flexible spout for precise liquid delivery and a squeeze mechanism for controlled flow. It is commonly used to rinse glassware, prepare solutions, or wash down surfaces, and are often equipped with a screw-on or snap-on cap to prevent spills and contamination.
