WTW OxiTop® Control B6/B6M

WTW OxiTop® Control B6/B6M - Determination of Soil Respiration
Laboratory method for determining the microbial soil respiration according to DIN ISO 16072.

• Simple and precise
• Cost-efficient
• Optimum measuring vessels for subsequent quantitative determination of CO₂

Soil respiration measurements are used for forecasting, surveying and checking remediation work, for biodegradability measurements of substances (pesticides, fungicides, fertilizers, etc.) and for carrying out toxicity tests.
Thanks to specially designed, test-proven vessels, these measurements are made accurate and simple with the OxiTop® Control System. A cost effective alternative compared to conventional methods.
Soil respiration measurements can be carried out in 2 different vessel types.
For actively respiring soils with strong CO₂ development, the MG 1.0 measuring vessel is recommended: its large opening (approx. 100 mm / 3.9 in dia.) easily fits large-volume CO₂ absorber vessels for later quantitative CO₂ determination.


Oxi Top® Control OC 110
With the global expansion of wastewater treatment, soil remediation, and waste treatment, the study and monitoring of biological cleaning treatments becomes increasingly important.
Biological tests are an important component, in addition to the usual physical-chemical measuring methods. In order to determine the microbial activity in and biodegradability of foodstuffs, pollutants, harmful substances or waste substances, respiration (depletion) measurements are often performed. In these measurements the respiration of the organisms is determined under defined conditions as the oxygen uptake or release of carbon dioxide.
Measurements are carried out via closed systems using the OxiTop®-C in combination with the OC 110 controller. Depending on the application, specially adapted measuring vessels are available, all of which are equipped with the necessary connection thread and some are autoclavable. Specialty packages are available with everything needed for a particular application.
