Hot/Cold Plate NG for screening of thermal hyperalgesia/allodynia Featured

The new Hot/Cold Plate NG offers a wide temperature range, presettable in the range -5°C to 65°C and is very quick and precise in reaching and keeping the preset temperature. 

The 35150 can be used as a conventional HOT PLATE, to carry out a rapid precise screening of narcotic type analgesic drugs according to the well known Hot Plate Test devised by N.B. Eddy and D. Leinbach.

As a COLD PLATE; the Cold Plate Test is useful in studying cold receptors and cold allodynia, a phenomenon very frequently observed in chronic pain on humans.
The lid reduces humidity condensation on the plate at low temperatures. Two working modes allow for testing at fixed temperature or at increasing/decreasing temperature (RAMP).

Brand new, user friendly software, to set up the experiment and manage the results.

An “auxiliary” Hot Plate, Cat. No. 35150-002, can be supplied as an optional, useful in the training and acclimation phase, for high-throughput tests. The 35160 combo-package, which includes a 35150 Hot/Cold Plate and a 35150-002 Hot Plate, can be taken into consideration.

    Optional
    An “auxiliary” conventional Hot Plate 35150-002 is available as optional; this self-standing unit may be used for the habituation phase before the test, thus reducing the use of the main unit to the test proper.

    The hot plate tests the pain response in animals, used in basic pain research and in testing the effectiveness of analgesics by observing the reaction to pain caused by heat.

    The method, devised by N.B. Eddy and D. Leimbach in 1953 (see paragraph 8.1-Method Papers) evaluates the reaction time of mice dropped on a heated surface and thus confronted with a heat stimulus applied to the plantar surface.

    Eddy and Leimbach used a behavioral model of nociception where behavior such as jumping and hind paw-licking are elicited following a noxious thermal stimulus. Licking is a rapid response to painful thermal stimuli that is a direct indicator of nociceptive threshold. Jumping represents a more elaborated response, with a latency, and encompasses an emotional component of escaping.

    When a central analgesic agent is administered to the animals, reaction time is markedly increased.

    The new Hot/Cold Plate 35100 has been designed to study more recently published cold receptor systems of neurons, which are not activated by cold but rather by chemicals, as well as the traditional cold receptors. These neurons are present in the CNS as well as PNS, but they are different from the neurons which sense pain.
