Description
BOD bottles 100 ml NS14/23 are specialised glass vessels for biochemical oxygen demand determinations and water analysis. Each bottle is manufactured to hold exactly 100 ml, providing the precise sample volume required by standard water investigation methods. An exchangeable NS hollow stopper with joint size NS 14/23 is fitted, so stoppers no longer need to be matched to individual bottles after cleaning and can be freely interchanged. This design simplifies laboratory routines while maintaining a reliable seal essential for oxygen-sensitive samples. Commonly known as Karlsruhe bottles or oxygen bottles, these containers are established tools in environmental monitoring, wastewater testing and quality-control laboratories. Supplied as single pieces from manufacturer Witeg, the bottles combine accurate volumetric calibration with the convenience of interchangeable ground-joint stoppers. Their construction supports repeated use in routine BOD workflows where exact fill volume and dependable sealing are critical for reproducible results.

A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. 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.
