However, in actual work, the sample tube needs to be shifted in the numbering and sample adding processes, and even the specification of 8 (short side) × 12 (long side) cannot meet the work requirement.

(2) The sample rack on the market is usually designed to be hollow on one side (long side) facing the user, and has no panel support or support surfaces on the left and right sides (short side). In actual work, the workload of nucleic acid detection is large, the types are many, and a sample placing frame needs to be marked; meanwhile, nucleic acid detection samples are usually processed in a clean bench or a biosafety cabinet, and users cannot observe two sides of the sample rack. The design of the support surfaces at the left side and the right side or the hollow design is inconvenient for a user to mark and identify the sample placing rack.

(3) The sample holders on the market are usually of the structure "sample panel (perforated) -sample bottom plate", where the two perforated sample panels have the same pore size. In actual work, the user needs to perform quick plugging operation on the sample tube due to the requirement of work efficiency. However, the user cannot ensure that the sample tube is vertically inserted every time, and the sample tube passes through the sample hole of the first layer of sample panel, but the sample tube cannot directly pass through the sample hole of the second layer of sample panel due to the angle, so that the sample tube is blocked by the second layer of sample panel, and the working efficiency is seriously affected.

(4) Nucleic acid detection samples are usually processed in a clean bench or a biosafety cabinet, and a user needs to observe and operate the nucleic acid detection samples through a glass panel and is far away from a sample placing rack. Sample rack on the market only possesses the function that the level was placed, puts into super clean bench or biological safety cabinet after, can only direct observation usually produce the maloperation near one row or several rows of sample pipes of user one side.
