Wire Gauze with Ceramic centre of size 12.5cmsquare, for use with tripod stand (also on sale from us, depending availability).Safely and confidently heat beakers, flasks etc with a Bunsen burner (or equivalent). The wire gauzehas a ceramic composite intended to aid in the dispersal in heat. The normal set-up is a ring stand which a support ring attached to it. The wire gauze is centered on the ring stand as to allow the open flame to be in contact with it to a certain extent, depending on the desired heat. In the context of laboratory experimentation, the combination of the wire gauze plus the added ceramic composite greatly aids in the even dispersal of heat. This means that an object placed over this type of wire gauze will receive a more uniform heat from a Bunsen burner than the naked flame of it. This property is specially important in various chemical processes where precise, even heat dispersal is sought after, as a consistent heat is crucial for the successful maintenance of the chemical process intended. Because of this desired heat dispersal ability, wire gauze can also be used as a cooling surface for beakers, Erlenmeyers flasks or other vessels without damaging the supporting surface (workbench, tabletop, etc.). This product is asbestos free.
