A lab trolley is a mobile platform used in laboratories to transport equipment, supplies, and samples. It's typically a sturdy, wheeled cart with shelves or compartments to organize and secure items during movement. Lab trolleys help reduce the risk of damage, contamination, or accidents by providing a safe and efficient way to move materials around the lab. They're often made of easy-to-clean materials like stainless steel or plastic and may have features like adjustable shelves, drawers, or locking mechanisms.
