Von Frey analgesiometer BIO-EVF-WRS

for animal researchfor micefor rats

A quick solution to determine the mechanical sensitivity threshold in rodents (mice and rats). Now wireless, to be free from annoying cables! This precise and easy-to-use electronic instrument is a must-have reference for your research in analgesia, nociception, neuro-pathologies and post-operative pain. Presentation 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 Von Frey was designed to improve results quality and facilitate measurements compared to classical Von Frey filaments, which require several stimulations for each measurement, thus inducing stress in the animals. Our Electronic version determines the mechanical sensitivity in one single measurement. The measured value is assessed with a resolution of 0.1 grams with a high-precision sensor which reduces the experimentation duration while improving repeatability between series. Results are shown on a large backlit display. The electronic instrument is not subjected to any temperature or hygrometry drift. The extended measurement range enables you to use the same instrument for different species (rats, mice, humans, etc.). The latest version of the Electronic Von Frey includes a new, entirely redesigned stimulator handle for an easier and more balanced manipulation. Thanks to the increased comfort, operator fatigue and tension are notably reduced during experimental sessions involving large series of animals. A new, more accurate and rigid sensor is embedded in the handle to decrease sensitivity to the operator's movements.
