Hargreaves Plantar Test

Hargreaves Plantar Test

Hargreaves Plantar test is widely used to test the thermal stimuli responses in the study of analgesic drugs in pharmacological experiments. Experiments are easy to perform as a rodent’s hind paw is exposed to a beam of radiant heat through a transparent glass surface using plantar analgesia meter. The latency to withdraw to the heat stimulus is recorded as the time for paw withdrawal in both injured and uninjured hind paws. Our Plantar test adopts microcomputer control method to obtain the pain threshold time automatically. The device contains an emitter/detector vessel, software controller, glass panel and animal enclosures. It can be used on 12 mice, 6 rats and other animals (cats, rabbits) unrestrained.

Benefits

• 6-12 rodent simultaneous stimulation.
• Microcomputer control, automatically measure the pain threshold time of plantar thermal stimulation in free state.
• 5-100% light intensity adjustment range, can be adjusted precisely according to the experiment.
• Time of irradiation can be flexibly set according to the irradiation intensity, to protect animals from being burned.
• Camera included to be directly connected to iPad or Mobile phone, assisting in observing the animal planta clearly.
