Placement holes are arranged at the upper end of the sample carrier plate. A baffle is arranged inside the placement plate and at the rear side of the sample carrier plate. A spring is arranged inside the placement plate and at the rear side of the baffle. Through the arrangement of the baffle and the spring, when using the multifunctional full-wavelength microplate reader, sample carrier plates of different sizes can be stably placed in the grooves inside the placement plate, so that the multifunctional full-wavelength microplate reader can be better used.

[0004] The above-mentioned utility model has the following problems:
