Description

Technical Field

[0001] The utility model relates to the technical field of ELISA instruments, in particular to an ELISA instrument with a storage in and out assist function. Background Art

[0002] The microplate reader is actually a phase-changing photoelectric colorimeter or spectrophotometer. Its basic working principle and main structure are basically the same as those of the photoelectric colorimeter. The light waves emitted by the light source lamp are converted into a beam of monochromatic light through a filter or a monochromator, and enter the sample to be tested in the plastic microporous pole. Part of the monochromatic light is absorbed by the sample, and the other part is irradiated on the photodetector through the sample. The photodetector converts the light signal of different strengths of the sample to be tested into a corresponding electrical signal. After pre-amplification, logarithmic amplification, analog-to-digital conversion and other signal processing, the electrical signal is sent to the microprocessor for data processing and calculation, and finally the display and printer display the results;

[0003] The prior art CN202223513552.1 is a multi-channel ELISA instrument, which is configured to place the ELISA plate into a placement opening opened on the carrier frame, and then drive the pressing frame to move upward through the fixing handle, and then push the carrier frame into the working chamber. When the tail end of the carrier frame conflicts with the second limit plate and cannot continue to move, the fixing handle is released, and the pressing frame is driven downward by the elastic force of the spring, and the pressing frame drives the pressing rod to press the four corners of the ELISA plate, thereby fixing the ELISA plate on the carrier frame. At the same time, the positioning rod will be inserted into the positioning hole to fix the carrier frame to prevent the carrier frame from accidentally slipping out. When the ELISA plate needs to be taken out, the carrier frame is pulled outward, and when the tail end of the carrier frame conflicts with the first limit plate, the carrier frame drives the ELISA plate to move to the top of the surrounding box, and the top plate is lifted upward by rotating the rotating rod to drive the cam to rotate, and the ELISA plate is lifted upward by the top plate, which is convenient for taking the ELISA plate.

[0004] However, when using the ELISA instrument for testing, only ELISA plates of fixed sizes can be placed on the carrier frame, which leads to limitations in the use of the test; therefore, it does not meet the existing needs. In this regard, we propose an ELISA instrument with an in-and-out storage assistant. Utility Model Content
