Activmeter

Presentation

Bioseb has developed a really simple-to-use and miniature actimetry system. The instrument uses weight to measure the locomotion and includes exhaustive functions to quantify rodent activity over short or long periods of time. It is usually set over up  to 48 hours to quantify the activity over the circadian cycle.

With a very competitive pricing for 1 to 8 cages, it is a 'must' when you need to simply quantify the locomotor phenotype of your mice and rats. The ACTIVMETER allows the accurate measurement of the rodent's activity in its familiar environment using the animal's ‘Home Cage' (including grid, pellets and bottle), and it can also be used in any other kind of environment (open field, etc.).

Operating principle

The Bioseb Activmeter uses 4 force sensors located at the 4 corners of the cage in order to precisely measure the movements of the animal with a precision of 1 centimeter. The fine analysis, in grams, of the distribution of forces on these sensors allows not only a measurement of the mobile activity of the animal but also of the immobile activity (grooming etc..). In addition, the software integrates algorithms to eliminate various biases such as litter movement in the cage and allows to follow the animal whatever the environmental conditions (food, drink, light...).
