In the light of DíAmour and Smith (1941), the Tail Flick method is useful for studying the effect of analgesic drugs such as narcotic drug or acute noxious stimulus on both mouse and rat. The tail flick test is used in determining pain sensitivity on animals by measuring latency of avoidance response when pain is induced by radiant heat from a light source to the animalís tail.

The SINGA Tail Flick Analgesia Instrument TF-01 measures reaction to radiant energy from a light source. The highlight of the device is the shutter-controlled halogen lamp which has the sensor built in for automatic tail flick detection. The lamp is located below the animal to provide a less confining environment and radiant heat provides a constant temperature to the animalsí tail, avoiding the lamp warm-up temperature variations.

The animal is generally restrained and its tail is placed on a sensing tail groove on top of the instrument. When the animal reacts against pain, it flicks its tail out of the beam which automatically freezes the built-in latency timer and the stimulation stops. The reaction time from activation of the light beam to the tail flick is automatically presented on a digital display. Response time is measured in 0.01 second increments and displayed on a digital clock. Windows-compatible software may be directly exported to a computer for statistical analysis.
