Crocus’s Hot Plate Analgesia Meter performs rapid & precise screening of analgesic drug properties on small laboratory animals. Hot Plate Analgesia Meter has been developed for hot plate test. Pain sensitivity to heat is by placing the animal on the top of aluminum plate and starting the timer. The operator stops the timer at the instant the animal lifts its paws from the plate, reacting from discomfort. The stop watch displays the latency to measurement of the animal’s resistance to pain.
