| Automated Constant Volume Respirometry |
Constant volume respirometry has a long and honorable history dating back hundreds of years. It's a sensitive technique that's ideal for measuring the metabolic rates of small animals quickly and easily. |
| Respirometry: Pull Mode, Multiple Animal, CO2 only |
This respirometry technique is commonly used for performing respirometry on multiple animals, where the animals are small and/or have low O2 consumption and carbon dioxide emission rates. |
| Respirometry: Pull Mode, Multiple Animal, Oxygen only |
This respirometry technique is commonly used for performing respirometry on multiple animals, where the animals are small and/or have low O2 consumption and carbon dioxide emission rates. |
| Respirometry: Push Mode, Multiple Animals, With Subsampling (Carbon Dioxide only) |
This respirometry mode is commonly used for performing respirometry on multiple animals, where:
|
The animals are large and/or have high oxygen consumption and carbon dioxide emission rates, and/or |
|
Fast switching between respirometer chambers is necessary |
|
| Respirometry: Push Mode, Multiple Animals, With Subsampling (Oxygen only) |
This respirometry mode is commonly used for performing respirometry on multiple animals, where:
|

|

|
| Respirometry: Push Mode, Single Animal, With Subsampling (Carbon Dioxide only) |
This respirometry mode is commonly used for larger animals such as mammals and birds, and - thanks to the sensitivity of carbon dioxide-based respirometry - for rapid and convenient measurements on smaller animals down to Drosophila in size. |
| Respirometry: Push Mode, Single Animal, With Subsampling (Oxygen only) |
This respirometry mode is commonly used for larger animals such as mammals and birds. These animals require a flow rate greater than the 200 ml/minute that can be passed directly through the gas analyzers. |
| Sable Systems Arthropod MR Calculator |
This JavaScript-based page lets you predict the metabolic rate (MR) of most common terrestrial arthropods. |
| Using the MAD-1 Motion/Activity Detector |
The MAD-1 activity detector is an absolute requirement for the measurement of reliable basal metabolic rates in animals from mouse to rat size (and above). |
| Using the AD-2 Activity Detector |
The AD-2 activity detector is an absolute requirement for the measurement of reliable "standard" metabolic rates in arthropods or other small animals. |
| Disabling the Multiplexer's "Purge" Facility |
To avoid the decline in oxygen concentrations (and buildup of carbon dioxide concentrations) that occur when an animal is enclosed in its sealed respirometer chamber by the respirometer multiplexer, you need to take advantage of an ingenious feature it has. |
| Span Gases - Where To Get Them And How To Use Them |
All gas analyzers must be calibrated regularly. Most analyzers require zero calibration and span calibration. |
| Scrubbing CO2 from Air |
For obtaining real-time metabolic data on small animals, especially arthropods, CO2 emission rate is often the only practical variable to measure. |
