The instrument adopts a semi-open design and is compatible with mainstream manufacturers' PCR reagents, supports sample tube loading, equipped with 12*4 independent detection positions and multiple sets of pipetting arms, and is equipped with 6 fluorescence channels as standard, combined with independent temperature control modules to achieve an efficient mode of "on-the-go pick-up, pick-up and inspection", with a single-day detection throughput of 120 tests, and at the same time, the innovative use of individual reaction cups to flexibly prepare on demand (as much as needed) to avoid reagent waste, take into account the rapid detection needs of scattered samples in emergency, outpatient peak and grassroots scenarios, and improve laboratory efficiency and cost controllability with a balance of automation and flexibility. With open compatibility and efficient stability, it can easily meet the needs of outpatient, emergency, hospital laboratory departments, and epidemic prevention and control. Provide "flexible" solutions for testing users.
