Yes, many parts of a dropper can be sterilized, but not all parts tolerate the same method. Glass bottles and glass pipettes withstand heat well, while rubber and TPE teats and plastic collars can be damaged by high temperatures or certain chemicals. The right method depends on the materials, so the supplier’s specification and the…
To clean a dropper for pharmaceutical bottles, take it apart, rinse each part with warm water, wash with a mild detergent, rinse thoroughly with purified water and let everything dry completely before reassembly.

In pharmaceutical-style bottles the pipette is one part of the dropper, and the teat creates the suction that fills it. Dropper and pipette:…
Droppers for chemistry are small tools for transferring and adding liquid in drops or small volumes. In a laboratory this usually means a Pasteur pipette with a rubber bulb, a plastic transfer pipette, or a dropper bottle that holds an indicator or reagent. They are used for convenience and speed, not for exact measurement. Common…

Droppers are used in cosmetics,…
