Embodiment 1
[0040] Such as figure 1 As shown, the calibration device of the present invention includes a base 1 and a top cover 2 matched with the base 1 . Preferably, the opposite surfaces of the top cover and the base are rectangular, and the two are detachably connected by screws.
[0041] see further figure 2 A fixing device 3 for the temperature sensor probe is provided on the side of the base 1 pointing to the top cover 2, so as to fix the temperature sensor probe of the temperature calibration device for the PCR instrument. As a preferred solution, in order to ensure the best temperature conduction effect, the fixing device is blind holes 4 arranged in a matrix, and the spacing of blind holes 4 can be determined according to actual needs, for example, for a specific type of PCR instrument temperature calibration device , the spacing of the blind holes 4 is set to be the same as that of the temperature sensor probes of the calibration device, so as to achieve optimal matching.

Embodiment 2
[0045] Such as Figure 4 As shown, in order to facilitate the fixing of the data line of the PCR instrument temperature calibration device, on the basis of the calibration device shown in Embodiment 1, a hollow line-passing tube 7 matching the line-passing hole is further provided, and the data line passes from the accommodation space 5 Pass through the wire through-hole 6 and then wear the hollow wire-passing pipe 7. In order to further prevent the dissipation of heat, the correction device also includes a wire tube cover 8, which matches the opening of the hollow wire tube 7, for example, the outer diameter of the lower part of the wire tube cover 8 shrinks so that it can be inserted into the hollow in the wire-passing pipe 7. The wire-passing tube cover 8 is provided with a wire-passing slit 9 for the data line (usually a cable) of the PCR instrument temperature calibration device to pass through. As a preferred option, such as Figure 5 As shown, the wire passage slit 9...
Embodiment 3
[0047] On the basis of embodiment 1 or 2, this embodiment 3 demonstrates a preferred calibration method using the calibration device of the present invention.
[0048] S01. Put the PCR instrument temperature calibration device into the base 1 of the calibration device of the present invention, so that the temperature sensor probe of the PCR instrument temperature calibration device falls into the corresponding blind hole 4 .
[0049] S02. Pass the data line of the PCR instrument temperature calibration device through the line passing hole 6 of the top cover 2 of the calibration device of the present invention, in one embodiment through the line tube 7, and then buckle the top cover 2 Put it on the base 1 and close the cover.
[0050] S03. Put the calibration device into the oil tank of the precision temperature measuring device, put the standard platinum thermometer into the oil tank, and connect the PCR instrument temperature calibration device and the standard platinum therm...
