Abstract: An infected nail of a digit of a patient is treated using apparatus including an enclosure capable of housing at least a distal end of at least one digit of a patient having an infected nail. The apparatus also includes a heater and a nail infection agent-containing member housed within the enclosure and positionable against an infected nail at the distal end of a digit housed within the enclosure. The heater is in heat-transfer relationship with the nail infection agent. In this way heated nail infection agent can be maintained against an infected nail by the nail infection agent-containing member.

Abstract: A multi-well microfiltration apparatus and method are provided and feature a manual touch-off system for transferring pendent drops hanging from discharge-conduits of a discharge-conduit array to respective receiving wells or receiving holes of a corresponding receiving array, with minimum or no cross-contamination between the discharge conduits, or the receiving wells or receiving holes. The manual touch-off is achieved by manually shifting a carriage that supports one of the arrays, into a position whereat pendent drops of fluid hanging from the distal ends of the discharge conduits contact the inner sidewalls of the corresponding receiving wells or receiving holes of the receiving array.

Abstract: A heater module is described that includes a heat distribution plate including a bottom portion having first and second sides and a plurality of projections extending away from one of the sides. A heat source is provided for heating the heat distribution plate, and, optionally, a heating tray can be used to receive the heat source and heat distribution plate. The heater module is adapted to engage a sample purification tray having a plurality of purification and/or discharge columns which can extend through openings in the heater module and direct a sample into a sample receiving tray. Methods of heating samples using the heater module are also described.
