IDEA’s one-task devices are the essence of our modular technology performing several tasks such as
stirring/mixing, sensor integration, gas/liquid handling, pumping, light control for photo-bioreactors, temperature control. Some devices can be “stand-alone” whereas others need to be integrated into an equipment (at least one Industrial Grade PC, IGPC). Just click on the device and see what task can perform.

Respirometers are testing devices to assess properties of materials or optimize bioprocess parameters. They are mainly of 4 distinct types, depending on the measured parameters:
A) CO2 in the headspace,
B) O2 in the liquid phase,
C) pressure in the headspace,
D) volumes and flow rates of gas.
CO2 (A) and O2 (B) respirometers are typically applied to aerobic processes, maintained as such by continuous or intermittent aeration. Differently, respirometers C and D can be applied to both aerobic (O2 consumption), fermentative processes (CO2 production, H2 productions) and biogas production (CH4 and CO2 production).
IDEA is the only company that has developed all the 4 technologies to provide unconditional advice depending on the test the user needs to carry out.
The choice of the respirometer must be made based on the application, the requirement to follow an ISO standard and the user's confidence in a specific technology.
Select by the application or contact us for a custom respirometer:
- PLASTIC respiromiter - to asses plastic biodegradability and compostability;
- BIOGAS respirometer - to carry out BMP/SMA/ATA assays;
- SOIL respirometer - to asses the microbial activity in soil and the effect of nutrients/pollutants/…
- OUR respirometer - to study aqueous systems and calculate OUR (Oxygen Uptake Rate).
SOIL respirometry
ENVIRONMENT LIFE SCIENCE TEST EQUIPMENT
Pre-Order
The SOIL respirometer has been developed for the determination of soil microbial respiration of aerobic, unsaturated soils.
We supply 4 different configurations:
- BASE - based on manometric respirometry (ISO 16072 sec. 5.4), suitable for the determination of O2 uptake;
- INTERMEDIATE - based on NIR CO2 tracking and optionally intermitted aeration, suitable for the determination of CO2 release;
- ADVANCE - based on NIR CO2 tracking and continuous aeration (ISO 16072 sec. 5.6), suitable for the determination of CO2 release;
- CUSTOM - a custom respirometer tailored to specific needs based on pressure/CO2/ideaflow w/wo intermitted/continuous aeration/O2 bag that can also be adapted to other application (e.g. plastic, biogas).
Systems measuring CO2 do not distinguish between CO2 released from microbial activities and CO2 resulting from abiotic processes. For alkaline soils and soils with a high organic matter content, which can release considerable amounts of abiotically CO2, methods using O2 uptake are recommended.
Anyway, both the 2 configurations are suitable for tests with the addition of a substrate (substrate-induced respiration), or without substrate addition (basal respiration) to determine:
- the microbial activity in soil;
- the effect of additives (nutrients, pollutants, soil improvers, etc.) on the metabolic performance of microorganisms;
- the microbial biomass;
- the metabolic quotient qCO2.
