The present application relates to the field of molecular detection technology, and in particular to a
cartridge and a molecular diagnostic platform. The
cartridge includes a
cartridge body, a first pipetting valve, a
test tube rack and a transfer unit; the cartridge body is formed with a plurality of first
reagent compartments, the
test tube rack is connected to the cartridge body and a
test tube is installed in the test tube rack; the first pipetting valve is movably connected to the cartridge body, the first pipetting valve is formed with a first valve cavity, and as the first pipetting valve moves to different positions, the first valve cavity can be respectively connected to a plurality of first
reagent compartments, so that
reagent transfer can be performed between the first pipetting valve and the first reagent compartments connected thereto, and the first pipetting valve can transfer the reagent in the first valve cavity to the test tube through the transfer unit; therefore, when extracting sample
nucleic acid, the transfer of reagents can be completed efficiently and fully, and the operation is simple; it is not easy to cause
contamination to the sample during the whole process, so as to ensure the purity of the extract and the accuracy of the experimental results; at the same time, the cartridge has a simple structure and low equipment cost.
