The electronic model of Von-Frey filament combines ease of use and rapidity for the determination of the mechanical sensitivity threshold in rodent.
Description
description
Basically, a tip is applied against the central edge of the animal hind paw. Paw withdrawal caused by the stimulation is registered as a response. The corresponding force applied is recorded by the system and displayed on the large backlighted screen of the Von-Frey unit with a resolution of 0.1 grams. A different tip is used for rat (hard plastic tip) and mice (elastic spring tip).
Differently to the procedure using classical Von-Frey filaments, the threshold value can be obtained in only one test, and in a highly reproducible manner. A foot-switch is proved to carry out rapid hands-free experiments.
The new Electronic Von Frey EVF4 is provided with a easier and more comfortable handle. The BIO-CIS software can be used to automatically record the results on a PC through a RS 232 port (direct Excel exportation).
Component Included:
- Stimulus handle
- Hard (10 units) and soft (1 unit) tips for rat and mouse
- Footswitch
- Storage casing
- Software (only with 750976 EVF4S)
Stand and enclosure have to be purchased separately.
Key Features:
- NEW easier and more comfortable handle
- Provides objective and accurate data
- The threshold value can be obtained in only one test, and in a highly reproducible manner
- Elimination of the problems of filament standardization
- Stimulation of areas of equal size
- The end-point value is automatically recorded
- Real time force curves in BIOCIS software
