Abstract

The present invention provides an optical measurement device capable of cooling a heater in advance and lowering the temperature of a sample container in advance. The optical measurement device includes a casing provided with an optical measurement section in which a sample container accommodating a measurement specimen is placed; and a cup-shaped lid body which is attached to the casing so as tobe freely opened and closed, wherein a heater for heating the measurement specimen is provided at a position opposite to the upper surface of the sample container in a closed state and opened downwards, a cooling air suppy port for supplying cooling air to the interior of the lid body is provided on a surface opposite to the lid body in a closed state in the casing, an opening and closing gmechanism of the lid body has a pair of link arms connecting the lid body and the casing, and between the pair of link arms is provided with a straightening vane for bringing the cooling air from the coolingair supply port toward the heater.

Description

Technical field [0001] The present invention relates to an optical measuring device. More specifically, it relates to an optical measuring device used as an absorbance measuring device, a fluorescence measuring device, etc. having a heating mechanism. Background technique [0002] For example, in paternity testing, DNA measurement of bacteria, viruses, etc., a PCR method (polymerase chain reaction) is used. In the PCR method, for the purpose of heating a liquid measurement sample to a certain temperature or repeatedly heating it in a periodic temperature pattern, it is equipped with a sample container (PCR tube) containing the measurement sample. Heater for heating. [0003] In the case of heating the measurement sample, when only the lower part of the PCR tube is heated, the moisture in the measurement sample evaporates and condenses on the ceiling surface in the PCR tube. As a result, the target in the measurement sample The concentration of the substance changes. [0004] In o...
