The metrological characteristics of three-gas incubator directly affect the quality of cell culture. In order to promote the development of modern biotechnology, the corresponding calibration method is studied to ensure the accuracy and reliability of the measurement value. On the basis of fully understanding the structure and working principle of the three-gas incubator, the main measurement parameters were analyzed, and the calibration feasibility was analyzed in combination with the corresponding standards, measurement technical specifications and related research. The specific calibration method was determined, which was proved to be reasonable and feasible by experiments and provided technical basis for the effective traceability of the three-gas incubator.
Fast nucleic acid analyzer has developed rapidly recently due to the spread of COVID-19 virus. In order to calibrate the temperature parameters of fast nucleic acid analyzer, it is necessary to study its temperature field distribution and temperature change curve, so as to put forward a scientific and accurate temperature field simulation model. This article studies the heat transfer mechanism of the heating module of the fast nucleic acid analyzer based on the finite element method by using CATIA three-dimensional modeling software and ANSYS Meshing platform, and the dynamic simulation model of the temperature field is obtained by studying two typical types of fast nucleic acid analyzers. Thus, this article provides a basis for the research on the calibration device of the fast nucleic acid analyzer, and the simulation model can be used to verify the reliability of the calibration device.
