Electric Von Frey Anesthesiometer, Rat
from
Stoelting Co.
Description
The original Electronic von Frey is used to assess mechanical allodynia with rigid tips (threshold) and the “Supertips™” (flexible von Frey hairs) are used for sensory test on all test subjects. Researchers are able to plug up to 3 probes into a single unit. Multiple users have the ability to use one single unit for multiple studies. The systems are supplied with either a 90, 800 or 1000 gram probe. Probe type is determined by test subject.
When studies call for pain threshold, rigid tips are used when measuring sensory threshold one of the 15 Supertips™ are used. The Stoelting hairs are unique in design - each hair has a uniform tip of .8mm in diameter, eliminating the possibility of false readings that may occur due to the varying hair thickness when applied to test subject. Testing is simple, choose one of the supplied tips place on probe tip; apply pressure probe to test subject, upon reaction the unit will display and store your reading in grams, an easy, quick test system for all pain studies. An internal load cell is attached to the small tip, this is the central element in the system; which connected to the electronic system allows you digitally record your test results.
A limit indicator allows user to preset and select a maximum force limit within 1 gram of accuracy. A warning light informs the user that the preset limit entered has been reached by the system. Users are able to have identical results from two different operators.
