These implements are laboratory tools designed for safely gripping and transporting beakers, particularly when they are hot or contain hazardous substances. They typically consist of two arms hinged together, with jaws or prongs at the ends that securely hold the beaker. The construction materials are often metal, coated with a heat-resistant substance to prevent burns and ensure a firm grip. For example, a scientist might utilize these tools to move a beaker containing boiling water from a hot plate to a cooling rack.
The employment of such instruments is critical in maintaining safety within a laboratory setting. They prevent direct contact with potentially dangerous materials and reduce the risk of burns or chemical exposure. Historically, these devices represent a crucial advancement in laboratory safety protocols, allowing for the manipulation of glassware and chemicals without direct manual handling. This has contributed significantly to the reduction of accidents and the promotion of safer research practices.
