Abstract

The present invention provides an optical measuring device capable of cooling a heater in advance and lowering the temperature of a sample container in advance. The optical measurement device is characterized in that it includes: a housing provided with an optical measurement unit, and the optical measurement unit is provided with a sample container for accommodating a measurement sample; In the closed state, a heater for heating the measurement sample is provided at the position abutting against the upper surface of the sample container, and opens downward. A cooling air supply port for supplying cooling air to the inside of the cover is provided on the surface opposite to the cover in the closed state, and the opening and closing mechanism of the cover has a combination of the cover and the housing. The link arms are provided with a rectifying plate between the pair of link arms to direct the cooling air from the cooling air supply port toward the heater.

Description

technical field [0001] The present invention relates to optical detectors. More specifically, it relates to an optical measuring instrument used as an absorbance measuring instrument having a heating mechanism, a fluorescence measuring instrument, or the like. Background technique [0002] For example, in paternity testing, DNA measurement of bacteria or viruses, a device that performs PCR (polymerase chain reaction) is used. In an apparatus for performing 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, a sample container (PCR tube) for storing the measurement sample is provided. A heater for heating. [0003] In the case of heating the measurement sample, when only the lower part of the PCR tube is heated, the water in the measurement sample evaporates and condenses on the ceiling surface of the PCR tube. As a result, the target in the measurement sample The concen...
