It is used for vacuumizing the vacuum blood collection tube, it will automatically produce a certain negative pressure inside the tube and automatically load the products into the foam tray. Our Advantages 1. Vacuum stable, high efficiency Use high-precision vacuum test instrument to realize intelligent control. Combine with cylinder valve to control and realize high precision, high stability and high efficiency. 2. High vacuum balance Adopt vacuum upper suction, can effectively prevent the cap enter into the test tube before pressing the cap, so as to ensure the vacuum degree in the test tube meet the design requirements. 3. It can load the tube in the tray directly, save the manual operation, greatly improve the production efficiency.
