The Graham Field 400 series is a line of versatile, economical stethoscopes designed for general clinical use. Each stethoscope features a dual-head chestpiece with an anodized aluminum construction, offering a diaphragm side for high-frequency heart and lung sounds and a bell side for low-frequency murmurs. The flexible 22-inch PVC tubing is available in a wide spectrum of colors, allowing healthcare professionals to personalize their equipment or color-code by department. For patient comfort, the chestpiece includes a non-chill rim, and the binaurals are chrome-plated brass with soft-sealing ear tips to provide an airtight acoustic seal and minimize external noise.
