Description

Technical Field

[0001] The utility model belongs to the technical field of microplate readers, and in particular relates to a microplate reader with a pre-drying treatment mechanism. Background Art

[0002] An enzyme-linked immunosorbent assay (ELISA) reader, also known as a microplate reader, is a specialized instrument for performing enzyme-linked immunosorbent assays (ELISAs). It's essentially a phase-change photoelectric colorimeter or spectrophotometer, and its basic operating principle and main structure are essentially the same as those of a photoelectric colorimeter.

[0003] Existing microplate readers typically include a reagent plate, a light source, a photodetector, and a control panel. The reagent plate, typically made of transparent plastic, is used to hold the specimen to be tested. Light waves emitted by the light source are converted into a monochromatic beam through a filter or monochromator, entering the specimen held in a plastic microporous electrode. Part of this monochromatic light is absorbed by the specimen, while the remaining portion passes through the specimen and strikes the photodetector. The photodetector converts this optical signal, which varies in intensity depending on the specimen, into a corresponding electrical signal. After undergoing pre-amplification, logarithmic amplification, and analog-to-digital conversion, the electrical signal is fed into a microprocessor for data processing and calculation. The test results are then displayed on a display on the control panel.

[0004] Existing microplate readers need to clean the reagent plate during use to prevent residual samples on the reagent plate from affecting subsequent test results. After cleaning, the surface of the reagent plate is wet and needs to be dried before use, which affects the turnover efficiency of the reagent plate. Utility Model Content

The isolation net 14 is made of stainless steel and is in a grid shape. The isolation net 14 is used to isolate the heating wire 13, which improves the safety of the use of the heating wire 13. The side wall is rotatably connected to the door 26, and the side wall of the outer shell 1 near the door 26 is provided with a slot 29. The inner bottom of the slot 29 is fixed with a photodetector 11 for receiving the light source and converting it into an electrical signal for analysis. The inner top of the slot 29 is fixed with a light source lamp 10 for emitting a light source. The side wall of the outer shell 1 near the top of the control panel 7 is fixed with a control panel 7. The control panel 7 is coupled with the light source lamp 10 and the photodetector 11 through wires in turn. The light source lamp 10 and the photodetector 11 are located in the same vertical direction. The plate body containing the reagent is fixed. 401 is snapped into the inside of the slot 2 9, which improves the detection accuracy and can realize the detection and analysis of the reagent.

The specimens absorb part of the light, and the other part of the light passes through the plate 401 and is photodetected. The detector 11 absorbs and performs light source analysis and detection, and the detection results are displayed on the display on the surface of the control panel 7, thereby realizing the detection of enzyme biological content. When the inside of the reagent tank 402 adheres to water after the reagent plate 4 is cleaned, the operator can open the door 3 to leak out the slot 2, so that the operator can easily clip the plate body 401 into the inside of the groove 15, turn on the power of the heating wire 13 to generate heat, thereby increasing the temperature inside the slot 2, thereby accelerating the evaporation of water inside the reagent tank 402, thereby improving the drying efficiency of the reagent plate 4, and thus improving the turnover efficiency of the reagent plate 4.
