Electronic Von Frey Handheld
The Electronic Von Frey Handheld replaces manual filament testing with automated force measurement via a rigid metal applicator. A peak detection algorithm automatically scores paw withdrawal across three force ranges (0–50, 0–200, 0–1,500 gf) with 0.1 gf resolution.
Touch sensitivity in unrestrained animals is traditionally tested with Von Frey filaments — a tedious and experimenter-dependent assay. The Electronic Von Frey handheld device addresses these limitations with a force sensor and rigid metal applicator that automatically scores paw withdrawal responses using a peak detection algorithm. Force ranges span 0–50, 0–200, and 0–1,500 grams with 0.1-gram sensitivity.
Research Applications
The Electronic Von Frey Handheld is used to quantify mechanical pain thresholds in rodent models of neuropathic, inflammatory, and cancer pain. It replaces manual Von Frey filaments with automated force measurement, enabling objective, reproducible assessment of mechanical allodynia and hyperalgesia in drug efficacy studies and phenotyping experiments.

The Electronic Von Frey (Cat. 38450) is used in neuropathic pain research for automated, bias-free measurement of mechanical allodynia and hyperalgesia. Its force sensor with automatic peak detection eliminates observer bias inherent in manual filament testing, and it is cited across CCI, PNL, SNL, and diabetic neuropathy models.
What force ranges are available?
Three interchangeable force ranges are available: 0–50 gf, 0–200 gf, and 0–1,500 gf, with 0.1 gf resolution across all ranges.
How is paw withdrawal scored?
Paw withdrawal is scored automatically via a peak detection algorithm, or manually by the experimenter using an included foot pedal.
What power options are available?
The device operates on batteries, USB power, or standard mains power (100–240 VAC, 50–60 Hz).
How many animals can be tested simultaneously?
The modular enclosure system accommodates up to 12 mice or 6 rats simultaneously.
What is the warranty?
12 months standard warranty, extendable to 24 months upon product registration.
