Plethysmometer for Evaluation Paw Volume
The Plethysmometer is an useful instruments designed to measure small change in paw volume, it is typically used to measure the inflammation of the paws in rodents which is experimentally induced. This test provides effective evaluation on screening potential antipyretic, anti-inflammatory, anti-oedema properties of pharmacological substances.
The Plethysmometer, also call as Paw Edema Meter, is a precise and user-friendly instrument designed to measure small volume changes in experimental animals. It is commonly used in pharmacology and inflammation studies to evaluate paw swelling induced in rodents. This system provides accurate, repeatable, and efficient data for screening the anti-inflammatory, anti-edema, and antipyretic properties of potential therapeutic compounds.
By combining modern sensing technology with the physical principles of Newton’s laws of motion and Archimedes’ law, the Plethysmometer ensures exceptional measurement precision and reliability. The system converts buoyancy changes into measurable forces, enabling accurate calculation of paw volume in real time.
Application:
Pharmacological testing of anti-inflammatory and anti-edema compounds
Preclinical research on pain and inflammation in rodents
Evaluation of drug efficacy in paw edema models
Laboratory teaching and physiological experiments involving volume displacement measurement

Q1: What is a plethysmometer used for?
A plethysmometer measures small volume changes, typically used to assess paw edema or inflammation in rodents during pharmacological studies.
Q2: Can this plethysmometer be used for both rats and mice?
Yes, the BioMed Plethysmometer includes dedicated restrainers for both rats and mice.
Q3: What is the measurement accuracy of this system?
The system provides ultra-High accuracy up to 1 μL, ensuring precise detection of even minimal swelling changes.
Q4: Does it include software for data analysis?
The plethysmometer includes built-in data statistics and automatic calculation functions, easily to review the paw edema volume changes.
Q5: How does it differ from other plethysmometer systems?
The measurement principle is different. Our Plethysmometer measure the volume of the paw through the force and reaction force using ultra high precision pressure sensor, do not need other relevant standard devices, only need to use pure water in the cup.
