Liquid suction: direct liquid transfer and liquid overhead vacuum transfer
Liquids can be suctioned using either direct liquid transfer or vacuum over liquid methods. It is important to understand these differences when selecting the appropriate technique and pump solution. While liquid suction may seem like a simple task, choosing the right suction method can be challenging. One option is direct liquid transfer, where the medium is transferred directly using a liquid pump. In vacuum over liquid transfer, a vacuum is used to suction the liquid. Both methods have their advantages, but there are also limitations. Understanding these differences is crucial to meet the specific requirements of the application. If the focus is on liquid transfer rather than liquid suction, the lesser-known method of pressurized liquid transfer may serve as an alternative.
