An inoculation loop (also called a smear loop, inoculation wand or microstreaker) is a simple tool used mainly by microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate. [1] [2] This process is called inoculation.
The inoculation needle after incineration is cooled down on an uninoculated region of the agar plate culture. [1] Too much heat will kill off the inoculum during the direct contact of a flamed inoculation needle. [1] The inoculation needle is withdrawn from the agar culture after obtaining a small colony and the agar plate lid is then replaced.
The two holes at the end of a manual wire wrap tool. The wire goes in the one near the edge, and the post is inserted into the hole in the center. Automated wire-wrap machines, as manufactured by the Gardner Denver Company in the 1960s and 1970s, were capable of automatically routing, cutting, stripping and wrapping wires onto an electronic ...
A cable tie (also known as a hose tie, panduit [1], tie wrap, wire tie, zap-straps, or zip tie) is a type of fastener for holding items together, primarily electrical cables and wires. Because of their low cost, ease of use, and binding strength, cable ties are ubiquitous, finding use in a wide range of other applications.
Animation of heat-shrink tubing, before and after shrinking. Heat-shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical wiring.
Each loop of wire is called a turn. [2] In windings in which the turns touch, the wire must be insulated with a coating of nonconductive insulation such as plastic or enamel to prevent the current from passing between the wire turns. The winding is often wrapped around a coil form made of plastic or other material to hold it in place. [2]
