Pipettes

Pipettes are well suited for taking small quantities from glass bottles. With these closed pipettes, they take liquids as follows. First, press the rubber bellows together between your fingers without dipping the pipette into the liquid. Then dip the pipette into the liquid you want to remove. Finally, reduce the pressure rubber bellows slowly. Due to the negative pressure previously created in the pipette rubber, the pipette now sucks in your liquid. This allows you to absorb liquid in the pipette and drip it out drop by drop by pressing it again slowly between 2 fingers. This allows both drop-by-drop dosing and application of the drops to objects. If you reduce the pressure on the rubber bellows too quickly, air can be sucked into the pipette.
The pipettes consist of a rubber bellows at the tip, which is integrated into a closure. The intake tube, on the other hand, is made of glass. Therefore, it can be used and tolerated by many liquids without hesitation. I recommend that you rinse the pipette with clean water after each use. This extends the life of the pipette.
The pipettes are available in different lengths. Not every pipette fits in every bottle. Therefore, there are comments on each of them.
