NorthCoast Von Frey fiber yarn

Four core advantages make tactile assessment more scientific and efficient

• Nano level precision: calibrated separately with an error of less than 5%
  Each fiber filament is independently calibrated at a predetermined force value, and when the peak force threshold is triggered, the single filament bends with a repeatability error controlled within 5%. Cooperate with the 50% reduction foot reflex threshold formula（$g=(10^{[x+k\delta ]})/10000$）Quantifying pain sensitivity is as precise as a clock.

• Safe and portable: 90 ° foldable design, laboratory in pocket
  The handle can be opened and closed at a 90 degree angle, with a volume only the size of a palm when closed. The protective cover prevents probe damage, making it easy to carry around whether it's animal room shuttle or clinical rounds.

• Visual operation: color coding+non-invasive detection, zero learning cost
  The handle is marked with green/blue/purple/red and other colors according to the pressure level, which can quickly match the threshold without checking the table; Non invasive touch on the skin can complete the detection, avoiding animal stress or patient trauma.

• Full scene adaptation: 20 specifications+customized accessories, covering the entire research chain
  From NC2775-01 (0.008g, normal tactile sensation) to NC2775-19 (180g, protective perceptual loss), equipped with accessories such as rat and mouse testing cages, prism observation devices, and rat facial fixators, it meets the full scenario needs from basic research to clinical diagnosis.
