Detailed Description

The following embodiments of the present invention are provided as examples, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present invention. In addition, the present invention can be implemented or applied by other different embodiments without departing from the spirit of the present invention.

Referring to fig. 1 to 3, fig. 1 is a schematic perspective view of a non-tenon reagent chuck according to an embodiment of the present invention; FIG. 2 is a perspective view of another view (bottom) of a non-tenon reagent cartridge according to an embodiment of the present invention; and fig. 3 is a bottom view of a non-tenon reagent cartridge according to an embodiment of the present invention.

As shown in fig. 1 to 2, the present invention relates to a non-tenon type reagent chuck, wherein the non-tenon type reagent chuck 1 includes six clips 10 and a plurality of easy-to-detach points 20; ten reagent filling grooves 11 are formed in each clip 10, each reagent filling groove 11 is used for filling a biological sample extraction reagent, and the bottom of each reagent filling groove 11 is a tapered groove 12 with a wide top and a narrow bottom. Next, the easily detachable points 20 are disposed between two adjacent clips 10, so that the two adjacent clips 10 are connected to each other. The reagent extracted from the biological sample is placed in the reagent filling groove 11 according to different formula conditions, and can be stored for later use after being sealed by an aluminum film. After confirming the number of samples, the six clip 10 of the present invention can accommodate rapid stock preparation for a large number of samples, and if there are odd numbers of samples, the easy disconnect point 20 can be used to disassemble the clip to select the appropriate reagent dosage.
