An optical measurement instrument includes: an excitation light source () arranged to produce an excitation beam for at least one of samples to be measured and a detector () arranged to detect an emission beam emitted by one of the samples to be measured and to produce a detection signal responsive to the detected emission beam. The optical measurement instrument further includes an arrangement for controlling temperature of the samples to be measured. The arrangement includes: one or more temperature sensors () for producing one or more temperature signals responsive to temperature of a measurement chamber () of the optical measurement instrument, one or more heating resistors (-) arranged to warm the measurement chamber, and a controller () arranged to control electrical power supplied to the heating resistors on the basis of the one or more temperature signals.

Optical measurement instrument

An optical measurement instrument includes one or more temperature sensors () arranged to measure sample well specific temperatures from sample wells (-) arranged to store samples (-) to be optically measured. A processing device () of the optical measurement instrument is arranged to correct, using a pre-determined mathematical rule, measurement results obtained by the optical measurements on the basis of the measured sample well specific temperatures. Hence, the adverse effect caused by temperature differences between different samples on the accuracy of the temperature correction of the measurement results is mitigated.

Instrumentation and method for optical measurement of samples

An optical measurement instrument comprises operational modules (-) that are interconnected via a digital communication network (). Each operational module comprises a transceiver (-) connected to the digital communication network and arranged to support a pre-determined digital communication protocol employed in the digital communication network. Those operational modules that include a detector further comprise an analog-to-digital converter () for converting a detected signal into a digital form and a digital circuitry () for providing digital information based on the detected signal with address data related to a particular operational module to which the digital information is to be delivered via the digital communication network. As information is transferred between operational modules via the digital communication network using the pre-determined digital communication protocol, the operational modules can be tested independently of each other using a test bench system arranged to support the pre-determined digital communication protocol.

Optical measurement instrument with data transmission

Instrumentation and a method for efficient and reliable assaying and measuring samples. The teachings include an automated self-contained instrument, wherein the samples are located on wells of sample plates, and the instrument includes a plurality of units for processing or storing sample plates. The instrument may includes at least one dispensing unit for dispensing reagents or other assay components to the sample wells, at least two units for simultaneously processing or storing a plurality of sample plates, at least one unit for removing substance from the sample wells, and one or several measurement units for optically measuring samples in at least two measurement modes. Further, the instrument includes a manipulator for moving the sample plates in three orthogonal directions or combinations thereof and for rotating the sample plates in relation to a vertical axis for transferring the sample plates to the units.

Automated instrumentation and method for measurements of samples

An optical measurement instrument includes a measurement head and mechanical support elements arranged to support a sample well plate. The measurement head is moved towards the sample well plate and, after the measurement head has touched the sample well plate, the measurement head is moved backwards away from the sample well plate so as to provide a desired distance between the measurement head and the sample well plate. A sensor device is attached to the mechanical support elements and arranged detect a mechanical effect occurring in the mechanical support elements due to force directed by the measurement head to the sample well plate. Hence, the situation in which the measurement head touches the sample well plate can be detected without a need to provide the measurement head with a force sensor. This is advantageous because the measurement head can be a changeable module of the optical measurement instrument.

Arrangement and a method for controlling a measurement head of an optical measurement instrument

A method for taking a sample from a closed test tube without removing the stopper of the test tube. According to the method, the stopper of the test tube is pierced with a disposable piercing needle through which the sample is taken to the sample receptacle of the sampling device. From there the sample is dispensed with a dispenser needle. The sampling device comprises an adapting element for fitting the test tube, with the piercing needle first, to the sampling device, a cup-like sample receptacle and a suction device for drawing the sample that is in the test tube into the sample receptacle.
