Sprague Rappaport Dual Tube Stethoscope.

The Professional Sprague Rappaport Dual-Tube Stethoscope is a heavy-duty, multi-purpose diagnostic tool designed for high-performance auscultation. Unlike standard single-tube models, the dual-tube design provides two independent sound channels, one for each ear. This significantly improves acoustic separation and ensures that even the most subtle physiological sounds are transmitted clearly without external interference.

Advanced 5-Way Conversion Design This instrument features a turnable zinc alloy chestpiece that allows for 5 different ways of use. By rotating the acoustic stem, you can switch between the Membrane Head for high-frequency sounds and the Cup-type Head for low-frequency murmur auscultation. With the included interchangeable bells and diaphragms, it can be customized for adult, pediatric, and neonatal patients.

Customizable Fit and Comfort The stethoscope is equipped with a chrome-plated binaural headset featuring adjustable tension. To ensure a perfect acoustic seal, users can separate the ear tubes to reduce tension or squeeze them together to increase the pressure in the ear canal. The medical-grade PVC tubing is built for durability, resisting oils and alcohol to maintain its professional appearance over time.
