20210373040 · 2021-12-02 ·

The present invention relates to the field of temperature monitoring and controlling apparatus, more particularly, relates to a thermoelectric temperature controlled sample holder for biomedical analyzers used for the processing of biological samples. Specifically, in biomedical research, samples of single cell suspensions are loaded into a biomedical analyzer, e.g. a flow cytometer for analysis. Some flow cytometers are equipped with multi sample loaders that hold for instance microtiter plates which can contain multiple, up to thousands of samples. Processing of all samples is done sequentially, sample after sample and may take several hours between the first to the last sample. Depending on the type of analysis it may be useful to maintain the samples at a defined temperature for example, to maintain viability and integrity of the sample or to keep biological processes running at physiological temperatures. The present invention allows to maintain the sample holder at definable temperatures between 3° C. to 70° C.
