Description
Dropping bottles 20 ml are laboratory containers fabricated from brown glass of the third hydrolytic class for reliable dropwise delivery of reagents and solutions. They are equipped with a DIN thread GL 18 and supplied without screw caps, allowing users to choose compatible closures for their specific protocols. Approximate external dimensions are 71,5 mm height and 28,6 mm diameter, providing a balanced footprint that remains stable on the bench while fitting common storage racks. The soda-lime glass construction delivers solid chemical resistance toward many aqueous and organic liquids encountered in routine analytical and research work. Amber tinting limits light exposure and assists in safeguarding light-sensitive contents. These dropping bottles from manufacturer Marienfeld arrive packed in units of 195 pieces, facilitating cost-effective stocking for busy laboratories. The 20 ml nominal volume suits intermediate working solutions, indicators, buffers and specialty reagents that benefit from controlled drop dispensing and moderate headspace. Their geometry and thread standard ensure straightforward integration into existing pipetting-bottle and reagent-handling systems used across teaching, quality-control and research environments.

Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
