Abstract: Provided are devices, compositions, and methods for surface disinfection and decontamination; the devices generally adapted to contain a single or multi-component indicator composition, and optionally a disinfectant composition, and to dispense the indicator composition and optional disinfectant composition to a disinfectant solution, a surface, or a disinfectant article upon actuation of the device; also provided is an article of manufacture in the form of a removable cartridge adapted to fit a device described here, which may be pre-filled with a single or multi-component indicator composition as described here, and/or with a disinfectant composition, and one or more optional additives.

Abstract: A vacuum pencil holder for holding a vacuum pencil used for picking up semiconductor dies or chips during fabrication of integrated circuit devices. The vacuum pencil holder has a wand stand adjustable in angular position about an elongated supportive member to which it is fastened, so that a vacuum pencil placed on the wand stand can always be turned to a position within reach of a fabrication engineer. The vacuum pencil holder includes a curved piece integrally joined to the wand stand. A pair of bearing members, each of which is substantially half-cylinder shaped, are attached to opposite sides of the elongated supportive member so as to form a cylindrical bearing member surrounding the elongated supportive member. The curved piece is slidably inset in slots formed on the curved surface of the two bearing members. The vacuum pencil holder can thus be turned about the elongated supportive member, allowing the wand stand to be adjusted in position.
