Paw Edema (Plethysmometer) Meter

Description

The Paw Edema Plethysmometer from IITC Life Science is an instrument designed to quantify paw swelling in laboratory animals, primarily for evaluating the efficacy of anti-inflammatory compounds. The device operates by immersing the animal's paw into a water-filled cell. The displacement of water caused by the immersed paw creates a measurable change in pressure within the cell. This pressure change is electronically converted and displayed as a volume measurement in milliliters on a digital monitor. A key technical feature of this system is its pressure-based detection method, which avoids the measurement inaccuracies that can occur in other plethysmometers due to changes in water conductivity from repeated insertions or contaminants. This makes it a reliable tool for repeated, consistent measurements in pharmacological and inflammatory research.
