An ideal solution for efficient needle cleaning.
Needles and similar diagnostic components need to be cleaned every time they handle different reagents or samples. KNF's liquid diaphragm pumps are essential for keeping them clean. Diagnostic equipment frequently uses needles for the administration of reagents and the transfer of sample specimens to perform important diagnostic tests. These needles must be thoroughly cleaned to avoid cross-contamination and eliminate the risk of false positive test results. However, this process can be surprisingly challenging. To completely clean the needles, it is necessary to force cleaning solution through them at a sufficiently high flow rate to remove all residues.

Liquid transfer: direct liquid transfer and liquid level pressure transfer
When there is a need to transfer liquids, two different approaches can be considered: direct liquid transfer and liquid transfer under pressure. What are the differences and potential limitations? When transferring liquids, engineers can choose to directly transfer fluids using liquid pumps. There is also a lesser-known method that utilizes the pressure difference created by a gas pump to indirectly transfer liquids. To select the best method for the application, it is important to understand the differences, advantages, and limitations of both transfer methods. If suction is required, the liquid vacuum method may be an option.
