The 3M™ Littmann Classic III Stethoscope is the latest version of the stethoscope that helps millions of medical professionals achieve their best. The Classic III stethoscope offers high acoustic sensitivity for exceptional performance, plus a versatile two-sided chestpiece with tunable diaphragms. The Classic III stethoscope is used by students and medical professionals alike to identify, listen to, and study heart, lung, and other body sounds for physical assessment, patient monitoring, and diagnosis. Two-sided chestpiece with tunable diaphragms on both the adult and pediatric sides. Single-piece tunable diaphragm is easy to attach, and easier to clean because its surface is smooth without crevices. Pediatric side converts to a traditional open bell by replacing the single-piece diaphragm with a non-chill rim. Next-generation tubing provides longer life due to improved resistance to skin oils and alcohol; less likely to pick up stains. Small tunable diaphragm is useful for pediatric, small, or thin patients; around bandages; and for carotid assessment.
