Measurement using OxiTop® is based on pressure measurement in a closed system: microorganisms in the sample consume the oxygen and form CO2; the CO2 is absorbed by NaOH, creating a vacuum that can be measured as a mg/l BOD value. The sample volume used regulates the amount of oxygen available for a complete BOD. Measurement ranges of up to 4,000 mg/l can be measured using different volumes.
Complete package, ready for use, for 12 simultaneous measurements, with IS 12 Inductive Stirring System, universal power supply 100-240V/50/60Hz and 12 OxiTop® measuring systems, including accessories

The XD series instruments are ideal for routine and spectral analy sis. As true all-rounders, the XD 7000 and XD 7500 facilitate work rou tines, especially with automatic method recognition using barcodes, automatic cell recognition and more than 150 pre-programmed meth ods. In addition to analytical quality control, they also support Good Labor Practice (GLP). The instruments are available together with bar-coded test tubes and a wide range of accessories from a single source - which is also easy on your wallet. High-quality reference beam optics, usability, easy handling and multilingual global applica bility round off the versatility of the VIS and UV/VIS spectrophotome ters, which are also equipped for flexible on-site use
