Hot Cold Plate is used to measure the nociceptive threshold of analgesic compounds in mice and rats. Conventional constant temperature hotplate tests only measure latencies of stronger narcotic agents.
Hot/Cold Plate Analgesia Meter widens the range of analgesia researchto new levels. The unit is microprocessor controlled and can be used for both incremental heating and cooling from any starting temperature from -2 deg. c. to 65 deg. c in 0.5 degrees c. increments with 0.01s tolerance. The microprocessor monitors and controls the rate of heating/cooling which can be set from 25 deg c to 4 deg c or from 25 deg c to 55 deg c in less than 3 minutes. The front panel display shows all test results including length of test in .01 sec. increments, starting temperature and stopping temperature. The plate is uniformly heated/cooled at an adjustable rate and has automatic upper/lower cut-off limits. All parameters are entered via front panel keypad. i.e. rate of temperature increase/decrease, maximum/minimum temperature, date/time and animal number.
