Next, place the entire dispenser and the vial in a properly sized cleaning container, and then set the scale to the maximum separation volume. Secondly, separate the dispenser from the vial and remove all the remaining solutions (the make sure that the safety valve arrow points to the dispensing tube).
Thirdly, pour a suitable special cleaning solution (such as distilled water or acetone) into the cleaning container and immerse the dispenser in it. And then to repeatedly absorb and drain the solution several times. Finally, take down all the tubes to clean and dry separately.
