Solvent Solvent A solvent (from the Latin "solvō", "loosen, untie, solve") is a substance that dissolves a solute (a chemically distinct liquid, solid or gas), resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature. Common uses for organic solvents are in dry cleaning (e.g. tetrachloroethylene), as paint thinners (e.g. toluene, turpentine), as nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate), in spot removers (e.g. hexane, petrol ether), in detergents
Staple remover Staple remover A staple remover is a device that allows for the quick removal of a staple from a material without causing damage. Also known as a canassas, the best-known form of staple remover, designed for light-gauge staples, consists essentially of "a") two opposing, pivot-mounted pairs of thin, steep wedges and "b") a spring that returns the device to the open position after use. Although a simple metal wedge can be used for the same purpose, and although some staplers (especially small ones about long) feature such a wedge at their hinge end, use of the wedge tends to tear
