    Abstract: An optical measurement instrument comprises a measurement head (101) and mechanical support elements (102, 103) arranged to support a sample plate (106). The measurement head is moved towards the sample plate and, after the measurement head has touched the sample plate, the measurement head is moved backwards away from the sample plate so as to provide a desired distance between the measurement head and the sample plate. A sensor device (112, 113) 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 plate. Hence, the situation in which the measurement head touches the sample 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.

    Abstract: An optical measurement instrument comprises operational modules (101 -107) that are interconnected via a digital communication network (110). Each operational module comprises a transceiver (111 -117) 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 (118) for converting a detected signal into a digital form and a digital circuitry (119) 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.

    Abstract: A method for taking a sample (22a) from a closed test tube (11) without removing the stopper (12) of the test tube. According to the method, the stopper of the test tube is pierced with a disposable piercing needle (13) through which the sample is taken to the sample receptacle (16) of the sampling device (10). From there the sample (22b) 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

    Abstract: 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.

    Abstract: An optical measurement instrument according to the invention comprises one or more temperature sensors(122) arranged to measure sample well specific temperatures from sample wells(111-117) arranged to store samples (103-109) to be optically measured. A processing device (121) of the optical measurement instrument is arranged to correct, using a predetermined 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.
