Drop bottle, also known as drop bottle and drop dispensing bottle, as a container for liquid drop, flow liquid distribution and pipetting, has become a routine product in various chemical laboratories because of its convenient operation and wide applicability.

but such a conventional container is not common in geochemical and other isotope analysis and testing laboratories.

Because a drop of unqualified reagent may mean the scrapping of the entire experimental data.

however, due to material or process reasons, conventional drop bottles have more or less common problems such as reagent hanging on the wall, precipitation of impurity elements in the bottle body, uneven droplet size, and difficult control of the liquid discharge,these make users of isotope research afraid to choose easily.

the most commonly used material for dropper bottles is LDPE, which is low-density polyethylene. this material is soft, easy to process, and has low chemical resistance. It can be used to store diluted or weak acids, but cannot be used for high-concentration Strong acid, high impurity content and easy to precipitate.

in order to improve chemical resistance, various manufacturers have introduced drop bottles made of FEP, which have less impurities and can be used for high-concentration strong acids, but the uniformity of droplets and the sealing performance of the bottle cap are still not ideal.

Our all-PFA dropper bottles together make up for the gap in the isotope field of dropper bottles.

OurPFA dropper bottles are manufactured using unique stretch blow molding technology, each bottle has a very smooth surface, which minimizes the possibility of trace metal deposition on the bottle wall.

the excellent finish not only effectively avoids the deposition of trace metals, but also greatly improves the cleaning efficiency, even if it is reused many times, it will not cause pollution residue.
