Carolina Two-Point Discriminator – 100mm Scale for Sensory Tests

Description

Product Overview

The Carolina Two-Point Discriminator is engineered for reliable cutaneous sensation testing in both academic and professional settings. Constructed from high‑impact ABS plastic, the device features a molded, easy‑read scale that measures up to 100 mm, allowing precise determination of two‑point thresholds. Its compact dimensions (5.9 x 3.2 x 0.2 inches) and lightweight design (0.8 oz) make it easy to handle, store, and transport. The durable build ensures the instrument can endure repeated use without loss of accuracy, a critical factor for busy laboratory environments and classroom demonstrations.

Usage

Designed for versatility, this discriminator can be employed in a range of educational and research scenarios. In biology labs, instructors use it to illustrate sensory nerve function, while students perform hands‑on experiments to map tactile sensitivity across different skin regions. In neuroscience research, the tool assists in quantifying sensory deficits in animal models or evaluating the efficacy of pharmacological agents that affect peripheral nerve function. Its simple one‑point and two‑point stimulation options enable quick switching between basic tactile perception tests and more complex threshold assessments, making it suitable for both introductory courses and advanced investigations.
