Combinable nucleic acid pre-processing apparatus

A combinable nucleic acid pre-processing apparatus includes a sample transfer chamber transferring a sample from a sampling tube to a nucleic acid extraction kit, a nucleic acid extraction chamber performing a nucleic acid extraction of the sample in the nucleic acid extraction kit for obtaining a nucleic acid extract, an assay setup chamber preparing reagents and transferring the prepared reagents and the nucleic acid extract to an assay plate, and at least two bridging modules respectively disposed between the sample transfer chamber and the nucleic acid extraction chamber, and between the nucleic acid extraction chamber and the assay setup chamber. The sample transfer chamber, the nucleic acid extraction chamber and the assay setup chamber are separated and operated independently, and further, three chambers are also communicated through the bridging modules, so the nucleic acid extraction kit can be sequentially moved in the sample transfer chamber, the nucleic acid extraction chamber and the assay setup
