摘要： A temperature control apparatus for controlling the temperature of a plurality of cuvettes consisting of an annular sealed chamber containing a refrigerant, means fixed to the sealed chamber for receiving the sample cuvettes, a heater in thermal contact with the sealed chamber, and a temperature sensor in thermal contact with the sealed chamber. The sealed chamber may include a plurality of thermally conductive posts fixed to the chamber, the spacing between adjacent ones of the posts being adapted to receive the sample cuvettes.

摘要： A method of operating a clinical analyzer wherein the analyzer includes a plurality of reaction locations divided into two groups. Predetermined operations are performed on the first and second groups during corresponding processing cycles. A process that is common to both cycles is performed simultaneously for reaction locations in the first and second groups during only one of the cycles. The other of the cycles can thus accommodate operations unique to particular tests that would not otherwise be available on the analyzer. The common process may be washing of adjacent reaction locations included in the first and second groups.

摘要： Plunger operated pipet operable to execute different lengths of plunger movement during successive fluid pickup and fluid discharge operations or strokes. A stop member is movable between first and second locations in the pipet body to halt plunger movement at two different positions. A drive spring for driving the stop member from one location to the other is energized by a manually operable arming element and is retained in one location against action of the drive spring during a first plunger stroke. A release mechanism responsive to plunger movement during the first stroke disables the retaining means allowing the drive spring to move the stop member to the second location at which position the plunger is halted during the succeeding discharge stroke. The arming element is actuated by and in response to positioning of a replaceable tip on the pipet body. The arming element exerts a force on the tip sufficient to expel the tip from the body unless the tip is properly seated on the body thus ensuring that the pipet is armed if the tip is properly seated. A signalling system is provided which signals the occurrence of the second or fluid dispensing stroke of plunger movement.

摘要： A stepper motor positioning control utilizing phase detection of the stepper motor windings. The device utilizes crude positioning apparatus to position the attached turntable or the like in an approximate position. The phase detection of the stepper motor windings is then used to position the attached turntable in the exact location desired.

摘要： A nephelometer including an optical excitation system for directing light through a first window area into a cylindrical glass container and an optical detection system for quantitatively monitoring light scattered by a substance within the container and passing therefrom through a second window area. The optical detection system includes a lens system in optical alignment with the second window area and focused on an optical dark region on an inner wall of the container opposite the second window area. The optical dark region is free of internal light reflections. Therefore, the light monitored by the detection system is scattered light from the substance substantially free of internal light reflections representing background error.
