The new Bioseb Electronic Von Frey offers numerous, exclusive improvements and new functionalities, among which:

• 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 new force sensor is both more accurate and rigid, improving reproducibility from a more homogenous stimulation. The variation linked to sudden movements is drastically reduced. 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

Application domains
