Abstract: The fluorescence measurement system includes a host apparatus and a self-contained, multichannel optical cartridge. The host apparatus includes a well plate receptacle, and a stage having optical cartridge receptacles that are elongate along one axis of the well plate. The stage and the well plate receptacle are movable relative to one another in the direction of the other axis of the well plate. The optical cartridge engages with the optical cartridge receptacle and includes a linear array of optical assemblies each including an excitation light source, and an emission light detector to generate an intensity signal. The optical cartridge also includes, a memory to store calibration information for each optical assembly. The host apparatus additionally includes a processor to correct the intensity signal from each optical assembly of the optical cartridge using the calibration information received from the optical cartridge for the optical assembly.

Abstract: A wire winder includes a body configured to anchor a wire and such that the wire extends from the body. The body is at least partially surrounded by a rotatable bobbin journalled on the body. The wire is windable onto the body within the rotatable bobbin from a direction substantially aligned with a bobbin axis. The bobbin rotation is indexed by coaction between at least one projection or depression on the body and at least one depression or projection on the bobbin.
