Electronic Von Frey 4, Bioseb (CAT#: STEM-LEAR-1189-YJL)

Electronic Von Frey 4, model BIO-EVF4 is manufactured by Bioseb
16 years of experience in developing instrumentation for the Von-Frey test allows Bioseb to offer a new standard for mechanical sensitivity threshold measurment in rodents (mice and rats).
The electronic instrument is not subjected to any temperature or hygrometry drift.
A new, more accurate and rigid sensor is embedded in the handle to decrease sensitivity to the operator's movements.

Accuracy: +/-0.25% of full scale ( +/- 1.25g)
Internal Memory: up to 100 values
Power Supply: 220-240 V (other voltages on request)
Range: 0 to 500 grams (5N)
Resolution: 0.1gram

A lighter stimulator handle with the center of gravity placed more centrally for more precise movement and better control of the increase in force.
The system is also easier to use on mice.
New spring tips for mouse stimulation: by absorbing impact forces, they increase accuracy on the 0-20 grams range.
As well as all the classical functionalities that made our Electronic Von Frey a 'must have' for all your research projects in analgesia and nociception:
Large backlit LCD screen simultaneously displaying current and peak value
Statistical functions: average value and standard deviation are computed for each subject
Stand-alone instrument: internal memory allows the storing of up to 100 values, which may be transferred to a PC using our optional software
