BOD self check measurement OxiTop
IS
Respirometric OxiTop measuring system for BOD self check measurement with undiluted samples measuring ranges up
to 4,000 mg/l BOD possible
The BOD measurement with OxiTop is based on pressure measurement in a closed system: The micro-organisms in the
sample consume the oxygen and generate CO2 in the process. This is absorbed with NaOH. This will cause a vacuum
pressure, which can be determined as a measured value in mg/l BOD.
The sample volume used regulates how much oxygen is available in order for full BOD to run. With different volumes,
measuring ranges up to 4,000 mg/l BOD can be measured.
The OxiTop heads (green and yellow to differentiate between infeed and output) have an AutoTemp function: If the sample
temperature is still too cold, the start of the measurement is delayed automatically until a constant temperature is reached,
but at least for 1 hour.
In addition to the automatic saving of 5 measured values (1 value per day), you can also manually read other measured
values after these 5 days have elapsed, so that control values or measurements can be tracked over time (long-term).
The OxiTop IS is ready for use immediately, as we will always supply you with product sets including accessories.

Stirring platforms
Wear-free inductive stirring platforms are used to mix BSB and other samples during respirometric measurements according
to the respective application
Optimal exchange between fluid and gas phase thanks to process-controlled stirring
platforms
To adapt to the application, this is available in 3 sizes
Optimized for WTW thermostat cabinets
These wear-free inductive stirring platforms sold by WTW are optimized for respirometric measurements. Processor-
controlled stirring processes warrant continuous mixing and ensure error-free measurements by undisturbed rotating
magnetic stirrers.
