WPI's Mouse and rat tail cuff blood pressure measuring systems for preclincial research, a true turn-key system when it is key critical for determining accurate, consistent blood pressure on mice, rats or any other laboratory animal test subject. A compact, simple yet versatile system that can test from a single up to 200 animals at a time with independent control of each channel. Simple daisy-chaining of systems allow expansion of systems, up to 200 independently, controlled channels. No other system in the world has such vast capabilities as the IITC blood pressure systems. Single animal systems are controlled from the touch screen which allows keying in all necessary test setups. These rodent restrainers are used with the non-invasive blood pressure tail cuff system for mice and rats. They can also be use for tail vein injections or other studies where the animal needs to be restrained.
