Details:
"MARS" stands for Multiple Animal Respirometry System, and the SM version is optimized for small mammals such as mice and rats. Live-in cages are standard, allowing the animals access to food and water. SM-MARS systems come with on-site setup and training worldwide, followed by lifetime technical support at no additional charge. Our systems carry a unique three year warranty against defects in materials or workmanship.
The president of Sable Systems International is an internationally recognized researcher and expert in the field, and has literally written the book on the subject (Measuring Metabolic rates: A Manual for Scientists, Oxford University Press, 2008). Unlike the competition, our systems preserve all of their raw data, which can be re-analyzed at any time. Every step leading from the raw to the final data is meticulously documented and preserved. "Black box" systems, such as the competition's, are coming under ever-increasing attack by reputable scientists. With our systems, you will never have to mistrust the integrity and traceability of your data, and can publish with confidence now and in the future.
The SM-MARS system can be operated with no chemical scrubbers whatsoever, greatly reducing operating costs, environmental impact, and sources of error. Accurate measurement of water vapor pressure and barometric pressure allows for automatic compensation for water vapor dilution of oxygen and CO2.
The SM-MARS system is available in the following configurations:
SM-MARS-X where X is the maximum number of animals to be scanned. Standard numbers are 4, 8 and 16. The system can be expanded after purchase.
SM-MARS-XA where A denotes non-invasive activity monitoring of all animals, which is highly recommended.
Thus, an 8 channel system with activity monitoring would be specified as an SM-MARS-8A.
Being biological scientists, we are well aware that mice at standard laboratory temperatures are thermally stressed and exhibit an elevated metabolic rate. This is a fact of which many users of biomedical metabolic screening systems are not aware. As a consequence, most metabolic measurements on mice in the biomedical literature are amalgams of the animal's real metabolic rate and its response to hypothermic stress. Should you wish to avoid this almost universal error, we can work with you to fit a temperature control system within your space and budget. Because the requirements will differ widely from one installation to another, temperature control systems are quoted on a case-by-case basis.
