New set: WTW OxiTop® Control AN 6 BSB measuring system for determining biogas. Characteristics:. - Anaerobic degradation processes take place without oxygen. - The measuring bottle has side connections that can be filled with inert gas. - These ports are sealed with septa, which allows CO2 that goes into solution after anaerobic degradation to be removed and removed from the gas space by adding a CO2 absorber. - The resulting pressure difference is directly related to the CO2 concentration, the remaining excess pressure reflects the methane concentration. - The dismantling process can be tracked easily and over time using the "pressure" mode. - Microbiological growth and stress analyses: determination of the breathing rate (aerobic/anaerobic). - Special bottles with side ports and septa allow for smooth addition of substrates and solutions. - Changes in pressure may indicate a lack of oxygen, requiring refilling with oxygen or air (or other gases). For this purpose, a “warning pressure” or a pressure limit can be set so that interventions can be made on the system. - The current pressure can be saved to document interventions. - Long-term measurements are possible by recording the measurement data (max. 10 values). Scope of delivery:. - BOD measuring system for anaerobic operation. - With 6 measuring points and controller OC 110, 230 VAC, 50/60 Hz. - Including 6 MF45/1000 bottles (1000 ml each) with two connections and septa each. - 6 adapters OxiTop® AD/SK. - 1 stirring platform IS 6-Var Labprocure is responsible for this device.
