ELECTRONIC VON FREY ANESTHESIOMETER
Assessing mechanical allodynia with 15 SuperTips
To assess mechanical allodynia, which is a painful response to a light touch or pressure from a stimulus that is not normally painful, the Electronic von Frey Anesthesiometer was developed. The Electronic von Frey meter uses one of 15 different flexible von Frey hairs called “SuperTips™” (or rigid tips up to 800 grams). Each hair, regardless of model chosen, is exactly 0.8mm in diameter. This uniformity of design eliminates false readings and allows for comparison of test results. The Electronic von Frey can be used with chart recorders and analog/digital converters, and it never needs calibrated. This system includes either a 90, 800 or 1,000 gram probe. Mesh stands are available in a variety of sizes for large group studies.
Grip Strength Meter
Measure muscle hyperalgesia in rats and mice with the Grip Strength Meter, which gauges the forelimb grip force using a digital force transducer. Simply hold the animal by the tail and gently dangle it over the wire mesh plate until the animal grasps the plate with its forepaws. The force transducer, connected with the wire mesh plate, measures the strength of the animal at the time of the test. The battery-operated, electronic control device calculates the average of three measurements, and it holds the last maximum force in a “peak and hold” type readout until you reset it.

Hot Plate Analgesia Meter
Latency testing in rodents
To use the Hot Plate Analgesia meters, simply place the animals on a black anodized, aluminum plate (11 x 10.5 x 0.75”, 275 x 263 x 15 mm) and set the plate’s surface temperature to the desired set point (up to 75˚C). The plate maintains a consistent temperature throughout the test

Incapacitance Meter for Mouse and Rat
Test pain and inflammation in small animal hind limbs
The Incapacitance Meter uses a technique called dual channel weight averaging, which tests both hind limbs. This gives you a clean, stress-free correlation of the paw pressure test. Conduct control and testing of the animal at the same time. Place the animal in the holder with its hind limbs resting on the two weight-averaging platform pads. The controller records the average weight (grams) over the test period as the animal shifts its weight from each pad.

Incremental Hot Cold Plate for Mouse & Rat
Latency and threshold-based nocicetption
This safe, humane device for rats and mice is used for latency and threshold-based nocicetption, ramping temperatures for 0-70˚C. Because this hot cold plate is incremental, it measures latencies of much more than just the strong narcotic agents, broadening dramatically the range of analgesia research with devices of this type. Microprocessor-controlled, the Incremental Hot Cold Plate can heat or cool in increments of 0.1˚C, at a rate of 1-10˚C per minute. With uniform heating and cooling and upper/lower cut-off limits, this device is predictable and safe. It can also function as a constant temperature plate with great stability (0.1˚C). As soon as a reaction is observed from the chosen paw, the unit reverses to the standby temperature.

Mouse/Rat Restrainer
Plantar Test Analgesia Meter
his unit, which is designed for testing narcotics and strong non-narcotic drugs, offers both Plantar (Hargreaves Method) and Tail Flick testing with a single unit. Either testing system is also available individually.
II-390G : In plantar mode, the visible light/heat source is directed at the paw or other desired body part, and in tail flick mode it is directed at the subjects’ tails. Test up to 12 mice or 6 rats simultaneously.
PLANTAR TEST/TAIL FLICK METER FOR RAT AND MOUSE
This unit, which is designed for testing narcotics and strong non-narcotic drugs, offers both Plantar (Hargreaves Method) and Tail Flick testing with a single unit. Either testing system is also available individually. In plantar mode, the visible light/heat source is directed at the paw or other desired body part, and in tail flick mode it is directed at the subjects’ tails. Test up to 12 mice or 6 rats simultaneously. If desired, other animals like cats and rabbits may also be used. Tests are simple to setup. The focused, radiant heat/light source creates a 4 x 6 mm intense spot. Because the light is visible, you know when the test starts and ends. The equipment is silent (no whining or clicking sounds) to avoid triggering an automatic response in conditioned animals. You can set a humane cutoff timer that automatically shuts off the heat if no response is observed during the designated time frame.
Plethysmometer (Paw Volume) Meter for Mouse and Rat
- Constructed of sturdy clear, 1/4” wall acrylic
- Requires only mild soap and water solution to clean the restrainers (no ammonia based products should be used)
- Includes adjustable head gate and the end plate.
- Head gate and end plates can be removed easily to allows the animal to “walk-in” to the restrainer and avoids any trauma to the specimen.

QUATTRO 4-IN-1 ANALGESIA SYSTEM
This special package offers four tests, including Electronic von Frey, Plethysmometer, Randall Selittometers and the Grip Strength Meter. You get all four test modules and the electronic controller that is interchangeable with all four systems. The electronic controller has up to three inputs, so you can perform up to four unique tests with only one electronic system. If you prefer, you may build your system and you grow. Because of the modular design of these four systems, you need to order only one complete system. Then, the modules for the other three tests, which integrate into the system, can be purchased separately, as needed. The stand and sling for the Randall Selitto test are sold separately.
