Description
Iron crucible lid with a 45 mm outer diameter is a metal cover for laboratory crucibles used in heating, ignition, and ashing work. Placing the lid on a matching crucible helps retain heat, reduce spatter, and limit ingress of dust or foreign particles while samples are treated at elevated temperature. The lid is made of iron and has a net weight of 0,018 kg, so it can be handled readily with crucible tongs yet sits securely on the vessel rim. This crucible lid from manufacturer Usbeck is offered as a single piece for routine thermal procedures in analytical and educational laboratories. Iron construction provides mechanical strength for repeated furnace or burner cycles where a robust metal cover is preferred. The 45 mm outer diameter should be selected to suit the corresponding crucible size so that the lid seats evenly. Typical uses include gravimetric analysis, determination of ignition residue, sample pre-treatment before weighing, and demonstration experiments involving controlled heating of solids. As a straightforward item within miscellaneous laboratory materials, it supports everyday high-temperature workflows in research, teaching, and quality-control environments.
