Detailed ways

The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the microplate plate shelf applicable to the microplate reader comprises a pair of first frames 10 and connecting plates 20, the first frame 10 is a pair of parallel frames, that is, two mutually parallel frame, the connecting plate 20 is connected to the first frame 10 , the connecting plate 20 is perpendicular to the first frame 10 , and the connecting plate 20 is located at one end of the first frame 10 . An end of the first frame 10 away from the connecting plate 20 is movably connected to the limiting baffle 30 , and the first frame 10 is provided with a sliding through hole 11 for the limiting baffle 30 to slide. Sliding through hole 11 comprises: connecting through hole 111, the circular through hole 112 that is positioned at connecting through hole 111 two ends; The distance d between 10 is equal to the length of the long side of the 48-well microtiter plate. As shown in Figure 3, at this moment the distance between the limit stopper 30 and the connection plate 20 is the shortest, and the shortest distance b between the limit stopper 30 and the connection plate 20 is equal to the distance a between the centers of the two circular through holes 112. The plate 30 and the connection plate 20 can hold a 48-well microplate plate. As shown in Fig. 4, at this moment, the distance from the limiting baffle 30 to the connecting plate 20 is the farthest, and the farthest distance c from the limiting plate 30 to the connecting plate 20 is equal to twice the distance a between the centers of the two circular through holes 112, At this time, the limit baffle 30 and the connection plate 20 can block the 96-well microtiter plate. Both ends of the limiting baffle 30 are slidably connected to the first frame 10 through bolts 12 passing through the sliding through holes 11 . The bolt 12 slides in the connection through hole 111 and is fixed in the circular through hole 112 .
