Electronic von Frey Anesthesiometer
BLOOD PRESSURE

The original Electronic von Frey to assess mechanicalallodynia with rigid tips (threshold) & “Supertips™”
flexible Von Frey hairs for sensory test on all test subjects.

RESTRAINERS

The 2390 series enables researchers to plug up to 3
probes into a single unit. Multiple users have the ability
to use one single unit for multiple studies.

CATHETERS

Our system is the first system introduced to the market
over 9 years ago which finally allows researchers theability to test and automatically record pain thresholdvalues in a clean, accurate easy to use compact system.
The systems are supplied with either a 90, 800 or 1000
gram probe. Probe type is determined by test subject.

ANALGESIA

When studies call for pain threshold, rigid tips are used when measuring sensory threshold one of the 15 Supertips™ areused. The IITC hairs are unique in design - each hair has a uniform tip of .8mm in diameter, eliminating the possibility offalse readings that may occur due to the varying hair thickness when applied to test subject.
The systems will allow you to measure, store and display your test readings in grams based upon the amount of pressure
applied. Manually calculating results is no longer required with the IITC system.

BEHAVIORAL/ACTIVITY

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, aneasy, quick test system for all pain studies.
Features

ANIMAL RESPIRATORS

An internal load cell is attached to the small tip, this is
the central element in the system; which connected tothe electronic system allows you digitally record your testresults.
All EVF systems are calibrated at the factory and do not
require any type of constant calibration, adjustment orseparate calibrator to be purchased.

SYRINGE PUMPS

Our system is an easy, user friendly system which wasdeveloped to replace the traditional hairs but at the sametime enabling researchers to not only test sensory but pain
threshold in one system.

New Feature - Limit Indicator
Allows user to preset and select a maximum force limit within 1 gram ofaccuracy. A warning light informs the user that the preset limit entered
has been reached by the system. Users are able to have identical resultsfrom two different operators.

RESTRAINERSCATHETERSWhat are “Supertips™”
As reported by earlier papers varying probe diameter on von Frey hairs
is a serious problem. These patented “Supertips™” have a UNIFORM TIP
DIAMETER OF .8mm ON ALL 15 DIFFERENT VON FREY HAIRS! This is auniquefeatureavailable only on
Electronic von Freys by IITC Inc. Probe size no longer affects pain orSemi Flexible Polypropylenepressure thresholds and results are finally comparable!
(Hygroscopy Free) 5 per pack.8mm Supertip®

Rigid Tip

Blunt Tip
ANALGESIAThis instrument eliminates the poor data collection due to thehygroscopic nature of von Frey hairs (it is proven that relative
humidity can change the force by more than 100% between
28-52% relative humidity change!) Only an accurate readout canshow the actual force, not a number as on the handle of classic vonFrey handles. Bending at various degrees can change the force by
20-30% in every case, this is visible with an electronic readout only.
The natural limiting of force with flexible hairs is of great advantage.
This instrument makes the up-down method of finding threshold
unnecessary. Without using line adapter, Battery life is 50 hours.
