Hot Plate Test Analgesia Meter for mice and rats

Description

The Hot Plate Analgesia Meter from IITC Life Science is an instrument designed for assessing pain sensitivity, or analgesia, in rodent models such as mice and rats. The test involves placing an animal on a heated, anodized aluminum plate which measures 11 by 10.5 inches. The device records the latency period—the time elapsed until the animal exhibits a nociceptive response, such as licking or shaking a paw, or attempting to jump off the surface. By measuring this reaction time to a controlled thermal stimulus, researchers can evaluate the efficacy of analgesic compounds or study pain pathways. The unit typically includes a precise temperature control system to maintain the plate at a constant, pre-set heat level, an enclosure or cylinder to contain the animal on the plate, and a timer with sensors to automatically detect the endpoint behavior. This method provides a standard and reproducible means of conducting thermal pain threshold testing in preclinical research.
