Product features:

1. Good radial mixing effect: due to the function of the mixing unit, the fluid rotates from left to right, constantly changing the direction of the flow mixer, not only pushing the central fluid to the surrounding, but also pushing the surrounding fluid to the surrounding;

2. The rotation of the fluid itself will also occur at the interface of the adjacent components. This perfect radial circulation mixing will make the liquid mix evenly;

3. The mixing volume is small and adjustable, which greatly shortens the lag of gradient mixing;
