Plethysmometer : Accurate Measurement of Paw Volume for Preclinical Studies

A Plethysmometer is a precision laboratory instrument designed to measure small changes in paw or limb volume in rodents such as rats and mice. This device is widely used in pharmacology, toxicology, and inflammation research to assess edema (swelling) and the anti-inflammatory effects of drugs. Plethysmometer delivers high accuracy, repeatability, and ease of use, making it an essential tool for preclinical and research laboratories.

The Plethysmometer operates based on the fluid displacement method. When an animal’s paw is immersed into a measuring chamber filled with fluid, the displaced volume corresponds to the change in paw size. The digital system converts this displacement into a measurable output displayed on the screen, ensuring precise and repeatable readings.
