Abstract: A apparatus for assaying glycated proteins and other analytes in biological samples such as blood, in which a sample is presented to the apparatus, includes an inlet port between moveable between first and second inlets, such that the inlet can be brought into liquid communication with each inlet in turn. The inlet port accommodates a filter or binder. The apparatus also includes a microprocessor operable via a key pad, at least one light emitter and at least one light detector, a display and driver, and an A to D converter, and is operatively connected to a power source.

Abstract: A slicing machine has a vertically extending semi-cylindrical cassette carrying objects to be sliced. A motor rotates a horizontal cutting blade and in addition swings the cassette about a vertical axis so that an object in the cassette is swept past the blade. The machine has an opening in its base to allow slices to fall out. On operation of a starter switch the motor functions for one revolution of the cassette. The switch is positioned so that it can be operated by a receptacle offered up to the opening.
