Volumetric Drinking Monitor

Drinking Monitor measures liquid consumption of mice and other small animals with 20 microliters resolution. Liquid is delivered to the licking dispensers in measured 20 microliter drops by the special pump. The standard number of liquid dispensers is 8, but the system is capable of monitoring consumption for a few hundred animals at a time. There is no possibility of leaks, which plague other dispensers. Drinking Monitor can be equipped with circuitry, which will count licks, if such an arrangement is valuable to the researcher.
