A 5-inch (125 mm) square of wire gauze with ceramic center. Using wire gauze with an alcohol burner. Wire gauze or wire mesh is a gauze woven of metal wire, or very fine, gauze-like wire netting. Wire gauze is placed on the support ring that is attached to the retort stand between a burner and glassware, or is placed on a tripod to support ...
Wire gauge. For drill bit and drill rod gauge sizes, see Number drill sizes. Not to be confused with Wire gauze. A device for measuring American wire gauge. Wire gauge is a measurement of wire diameter. This determines the amount of electric current the wire can safely carry, as well as its electrical resistance and weight.
Structured packing is formed from corrugated sheets of perforated embossed metal, plastic (including PTFE) or wire gauze. The result is a very open honeycomb structure with inclined flow channels giving a relatively high surface area but with very low resistance to gas flow. The surface enhancements have been chosen to maximize liquid spreading.
A laboratory tripod is a three-legged platform used to support flasks and beakers. Tripods are usually made of stainless steel or aluminium and made light-weight for efficient portability within the lab. Often a wire gauze is placed on top of the tripod to provide a flat base for glassware. Tripods are generally tall enough for a bunsen burner ...
An unmounted resistive foil strain gauge. A strain gauge takes advantage of the physical property of electrical conductance and its dependence on the conductor's geometry. . When an electrical conductor is stretched within the limits of its elasticity such that it does not break or permanently deform, it will become narrower and longer, which increases its electrical resistance end-to-
Gauze. Gauze is a thin, translucent fabric with a loose open weave. In technical terms, "gauze" is a weave structure in which the weft yarns are arranged in pairs and are crossed before and after each warp yarn, keeping the weft firmly in place. [1] This weave structure is used to add stability to the fabric, which is important when using fine ...
A test tube holder is used to hold test tubes. [ 1 ] It is used for holding a test tube in place [ 2 ] when the tube is hot or should not be touched. [ 3 ] For example, a test tube holder can be used to hold a test tube while it is being heated. [ 4 ] Moreover, when heating the tube with liquid or solid contained inside, the holder ought to ...
Davy's first safety lantern, 1815 (at left) Diagram of a Davy lamp. The Davy lamp is a safety lamp used in flammable atmospheres, invented in 1815 by Sir Humphry Davy. [ 1 ] It consists of a wick lamp with the flame enclosed inside a mesh screen. It was created for use in coal mines, to reduce the danger of explosions due to the presence of ...
