76-0975 Electronic von frey For evaluating mechanical allodynia in rodents Panlab

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
