The Columbus Instruments Volumetric Drinking Monitor (VDM) features a previously patented micro-pump for measuring precise liquid consumption in small animals. When the animal consumes a drop, the next is automatically dispensed. This is ideal for hydration studies, behavioral research, and pharmacological evaluations, providing valuable insights into drinking patterns and fluid intake in various experimental contexts.

High-Resolution Liquid Consumption Measurement

The Volumetric Drinking Monitor offers 20-microliter resolution, ensuring precise measurement of liquid intake. Each drop consumed by the animal triggers the pump to deliver the next, providing continuous, reliable data. This high level of precision makes it superior to traditional lick counters, which can vary in liquid delivery.

Leak-Free Design with Flexible Setup

Unlike other systems prone to leakage, the patented micro-pump technology ensures no fluid waste or dripping. The liquid reservoir can be placed above or below the cage, making it versatile for different lab environments. The monitor can accommodate multiple liquid dispensers in a single or multiple cages, making it scalable to monitor hundreds of animals simultaneously.

• Resolution: 20 microliters
• Liquid Delivery: Micro-pump
• Reservoir: Can be positioned above or below the cage
• Dispenser Capacity: Standard setup supports 8 dispensers; scalable to hundreds of animals
