1. Fully automated design: with built-in standard sample preparation programs for multi-species bacteria testing, the instrument could complete the whole process automatically after the user places samples and consumables well (Petri dishes, tubes, etc.).

2. Code scanning module: automatically identifies the QR code/barcode on the sterile bag, enters sample information into the system, and determines the specific programs. 

3. Petri dish storage module: up to 396 empty and agar-filled Petri dishes can be stored to meet the spreading and pouring method requirements.

4. Liquid flapping and homogenizing module: dilute the samples with 10 times liquid, then homogenize the sample by auto-flapping. The integrated heat-sealing function retains the original homogenizing liquid.

5. Gradient dilution module: perform 10, 100, 1000 times gradient dilution for 20 samples. Cross-contamination is avoided by adopting 5ml disposable pipette tips.

6. Agar thermostatic function: magnetic stirring and thermal insulation functions ensure agar does not solidify or deposit. The pipeline is easy to dismantle and sterilize.

7. Pipetting module: with high precision, cross-contamination is avoided by adopting 5ml disposable pipette tips.

8. Bacterial spreading module: rotary and uniform spreading for each sample by an individually soft spreading stick to avoid cross-contamination and increase efficiency. After spreading, the agar can be overlaid by the top medium.

9. Agar filling module: up to 3 kinds of agar can be filled and shaken, and multi-species bacteria can be performed in one test. Working under metal bath insulation, the filling tube is reusable and easy to dismantle to sterilize.

10. Robotic arm:2 sets of high-precision robotic arms with intelligent control, the program centralizes the scheduling of all modules to improve test efficiency.

11. Inkjet printing module: inkjet prints the information on Petri dishes, which makes it easy to distinguish the sample, gradient, parallel sample and other information.

12. UV sterilization: UV sterilize the system to prevent airborne bacteria contamination.

13. Aseptic environment: a laminar flow hood is set on top of the equipment, and the internal micro-positive pressure of the system ensures aseptic.

14. Multi-terminal remote monitoring: the software’s main interface and real-time images of the internal operation can be remotely monitored through mobile phones and computer clients.

15. Multi-functionality: can be used individually for sample flapping, pipeing, gradient dilution, Petri dish filling and other routine laboratory operations.
