The invention discloses a full-automatic
nucleic acid extraction, amplification and detection instrument, which comprises a working box body and an operation display screen, wherein a
machine core device is arranged in the working box body, is electrically connected with the operation display screen and comprises a
nucleic acid extraction, amplification and detection device, a thermal
cycling device, an adjustable light supplement lamp device and an optical detection device; and the optical detection device is installed in the
machine core device and is positioned above the
nucleic acid extraction, amplification and detection device. A
start button on the operation display screen is pressed down, and the nucleic acid extraction, amplification and detection device carries out nucleic acid extraction, amplification and detection; after detection is finished, the adjustable light supplement lamp device can be automatically on so as to assist the optical detection device in photographing and detecting the nucleic acid extraction, amplification and detection device; through the operation display screen, a sample detection situation can be displayed; a whole process can be automaticallycarried out and does not need people to intervene and participate, an
automation degree is high, errors and cross
contamination caused by manual detection can be avoided, and efficiency is greatly improved.
