Suitable application workflows
Animal and human nutrition
Monitor fermentation gas production in ruminant, monogastric and human gut models. Gas Endeavour® III is used for in vitro digestibility studies, feed evaluation, feed additive screening and fermentation kinetics.
Biogas research
Use gas volume and flow data to study biological conversion, microbial activity and gas production behaviour in anaerobic processes.
Wastewater analysis
Follow gas production, gas consumption or oxygen uptake in wastewater, sludge and biological treatment studies.
Biohydrogen
Measure gas production in biohydrogen potential and dark fermentation studies.
Fermentation studies
Monitor gas production or consumption during ethanol fermentation and other microbial process studies.
Microbial activity
Evaluate the behaviour of microbial communities through gas production or gas consumption under controlled laboratory conditions.
Choose the configuration that suits your workflow
Choose your incubation setup
Gas Endeavour® III can be used with a thermostatic water bath, a shaking thermostatic water bath for animal nutrition workflows, or BPC® Air depending on the configuration and application.
BPC® Air
BPC® Air can be used as an air based incubation unit for Gas Endeavour® III instead of a traditional thermostatic water bath. It provides heating and cooling from 10 to 60 °C and removes the need to refill incubation medium during long tests.
Shaking thermostatic water bath
The Animal Nutrition configuration uses a shaking thermostatic water bath with 250 mL reactors, supporting controlled incubation and mixing in smaller reactors for in vitro fermentation studies.
Thermostatic water bath
The standard incubation setup provides water based temperature control for Gas Endeavour® III workflows. It is suitable for laboratories that already use water bath incubation or need controlled conditions for biological process tests.
