Description

For screening of inflammation or oedema in mouse or rat The Digital Plethysmometer is a micro controlled volume meter, specially designed for accurate measurement of the rat / mouse paw swelling. The Digital Plethysmometer is a highly useful tool to evaluate the inflammatory response experimentally induced in small rodents and to screen potential anti-inflammatory or anti-oedema properties of pharmacological substance. The water displacement produced by the immersion of the animal paw in the measuring tube is reflected in to the second tube, inducing the volume displacement. This displacement value is recorded. The control unit can be zeroed between successive readings by pressing the reset key, so as to avoid the error arising due to adherence of water to the paw of the animal. Foot switch allowing rapid hands-free experiments can be used to control the end point of the measurement.
