A luminometer () includes a light detector () configured to sense photons (). The luminometer () includes an analog circuit () configured to provide an analog signal () based on the photons () emitted from assay reactions over a time period and a counter circuit () configured to provide a photon count () based on the photons () emitted from the assay reactions over the time period. The luminometer () includes a luminometer controller () configured to, in response to an analog signal value of the analog signal () being greater than a predetermined value, determine and report a measurement value of the photons () emitted from the assay reactions over the time period based on the analog signal value of the analog signal () and a linear function (). Optionally, the linear function () is derived from a relationship between the analog signal () and the photon count ().

Embodiments of a dispenser and a dispensing method for an analyzer are disclosed herein. The dispenser can include a first structure containing a first fluid path and a probe containing a second fluid path. The first structure can include a heat source that can heat the first structure and a fluid contained in the first structure. The first structure can be physically and thermally connected to the probe such that the probe is indirectly heated by the heat source via thermal energy transferred through the first structure. The heat source can be controlled to heat the first structure to a first desired temperature and/or temperature range, which can result in the heating of the probe and the fluid contained in the probe to a second desired temperature and/or temperature range.

A method and system for automated immunochemistry or chemistry analysis are provided. The method and system provide a sample aliquoting section, a reagent pipetting section having a plurality of independent reagent pipetting stations, each operating on a cycle of a first period of time, and an incubate and wash and read section operating on a cycle of a second period of time to match the throughput of the system, where the quotient of the first period of time divided by the second period of time is a whole number, and the number of the independent reagent pipetting stations being equal to the whole number. The respective cycles of the independent reagent pipetting stations are staggered apart by the second time period, such that at least one of the multiple independent pipetting stations is available for working with the incubate and wash and read section at each operating cycle of the second period of time.
