ConXport Analgesiometer (Eddy's Hot Plate), The instrument consists of a flat, temperature-controlled heating surface, often made of metal or ceramic. The temperature of the heating surface can be precisely controlled and maintained at a constant level. The subject, usually a laboratory animal such as a rodent, is gently placed on the heated surface. The temperature of the heating surface is gradually increased at a controlled rate. Researchers closely observe the subject for signs of a pain response, which may include paw licking, jumping, or vocalization. The Analgesiometer can be used to assess the efficacy of analgesic drugs or interventions by measuring changes in response latency after treatment.  The Analgesiometer, commonly known as Eddy's Hot Plate, plays a vital role in the assessment of pain sensitivity and analgesic interventions. Its precise thermal stimulation and objective measurement of pain responses contribute to advancements in pharmacological research, pain management strategies, and our understanding of pain mechanisms. By offering a reliable and controlled platform for pain assessment, the Analgesiometer continues to be a valuable tool in alleviating pain and improving the quality of life for individuals experiencing pain-related conditions.
