KF12 250 ml Karlsruhe bottle – The ideal laboratory tool for uncompromising BOD measurement
The WTW brand's KF12 250 ml Karlsruhe bottle is an essential standard in the field of environmental analysis, particularly in Biochemical Oxygen Demand (BOD) measurement protocols. This flask has been developed to meet the strict requirements of laboratories seeking maximum precision in their measurements, while maintaining optimal analysis conditions from start to finish.
Equipped with an NS19 ground glass joint, the KF12 bottle is specially designed to accommodate BOD probes in a perfectly sealed manner. This technical detail ensures that the introduction of the probe does not disturb the internal environment of the sample by introducing external oxygen, a critical factor in obtaining reliable measurements. The characteristic shape of its neck plays a fundamental role in the accuracy of the results, as it allows the water displaced by the introduction of the sensor to be recovered without causing overflow or significant pressure variations.
Its 250 ml capacity makes it the ideal volume for standardised laboratory testing, while providing sufficient margin for comfortable reading and easy handling. Made from high-quality glass, the KF12 bottle is robust, resistant to moderate thermal shocks and perfectly suited for temperature-controlled incubations over several days, in accordance with standard BOD measurement protocols. It can be used in thermostatic chambers or automated systems such as OxiTop® platforms, which are compatible with WTW products.
Used primarily in water quality analysis, whether in wastewater, surface water or drinking water, this bottle allows analysts to work with confidence, even on complex sample series. Its efficiency and accuracy are also appreciated in university and industrial laboratories conducting research in microbiology, ecotoxicology or soil science. KF12 can also be integrated into biodegradability measurement protocols according to OECD 301F.
This product is designed for performance and scientific rigour. It is a proven benchmark in research and analysis laboratories for all applications requiring accurate and reproducible BOD measurement. Its compatibility with NS19 stoppers, whether glass or plastic (PPC), enhances its versatility and facilitates its integration into existing installations.
