Laboratory peristaltic pump liquid dripping how to solve

A user who did the reagent packaging experiment responded that when the laboratory peristaltic pump was doing the experiment, there would be a few drops of liquid dropping in the moment of suspension, which affected the experimental effect, and asked if there was any way to solve it?

Peristaltic pump manufacturers to give you answers, I hope to help you.

Laboratory peristaltic pump in the operation process, the liquid will drip from its outlet, so what is the cause?

In fact, this reason is caused by the gravity of the fluid itself, because only one end of the peristaltic pump hose is connected with the atmosphere, the other end is squeezed by the peristaltic pump wheel and can not be connected with the atmosphere, the liquid will produce tension in the pipeline, but because the tension can not overcome the gravity of the liquid, the liquid will still fall. To put it bluntly, the liquid's tension is less than the liquid's gravity, which leads to the phenomenon of liquid dripping. Is there a way to solve this problem?

Of course it can be solved. By reducing the diameter of the hose outlet, we can easily increase the tension of the liquid in the pipeline, thereby solving the phenomenon of liquid dripping. Of course, in addition to this simple method, we can also solve the drip phenomenon by adding a one-way pressure valve at the outlet. When the peristaltic pump works, the pressure generated by the pump itself opens the check valve, and when the pump stops, the check valve automatically closes when the pressure disappears.

The laboratory generally has low requirements for the speed of flow, and can reduce the drip phenomenon by reducing the diameter of the peristaltic pump hose.
