Description
- This system automates the assessment of mechanical sensitivity and paw withdrawal thresholds in rodents
- Force generation range: adjustable from 0.1 to 100 grams
- Programming increments: settable in precise 0.1g steps
- Force ramp duration: continuously adjustable from 0 to 50 seconds
- 4.3″ resistive touch screen graphic display for real time monitoring and parameter setup
- Data resolution: latency time is captured and displayed in 0.1- second increments
- Stimulus delivery: uses a unique 0.5mm diameter plastic filament to exert the linear force ramp
- Filament travel: max vertical extension reach of 12mm
- Targeting system: mounted on a manually adjustable, mobile mechanical platform fitted with an angled alignment mirror to view the animals paw from underneath
- Automated detection: an embedded sensor detects the exact moment of paw withdrawal, instantly arresting the filament to prevent tissue damage and locking in the threshold metrics
- Perforated mesh grid: a large, sturdy metal testing floor configured with uniform 5×5 mm square openings to grant unobstructed filament access to the paw pad
- Support architecture: heavy-duty, elevated metal support pillars that hold the grid plate high enough to allow the electronic touch stimulator arm to slide smoothly underneath
- 100-240VAC 50/60Hz
