The production line adopts highly integrated modular design, which integrates the core processes of tube loading, liquid addition, drying and vacuuming into independent units, with the volume of each module only 1/3-1/2 of the traditional equipment, and the overall length of the line reaches 2.6 meters (the traditional line length reaches 15-20 meters), which is suitable for the layout of narrow space. The blood collection tube mini assembly line includes stations for loading blood collection tubes, dosing reagents, drying, sealing and capping, vacuuming, and loading trays. With PLC and HMI control, the operation is simple and safe, and only 1-2 workers are needed to run the whole line well. Compared with other manufacturers, our equipment is characterized by compactness and space-saving features, including smaller overall size, higher automation and stability, and lower failure rate and maintenance cost.
