The Hot & Cold Plate Analgesia Meter performs rapid & precise screening of analgesic drug properties on small laboratory animals.

Orchid’s Hot & Cold Plate Analgesia Meter has been developed for both conventional hot plate tests and cold pain test.

Pain sensitivity to heat is assessed by placing the animal on the top of aluminium 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 front panel timer displays the latency to react, a measurement of the animal’s resistance to pain.
