The 3M Littmann Classic III Stethoscope features a two-sided chestpiece with tunable diaphragms on both adult and pediatric sides for versatile auscultation. Its single-piece tunable diaphragm attaches easily and is simpler to clean thanks to a smooth, crevice-free surface. The pediatric side converts to a traditional open bell by replacing the diaphragm with a non-chill rim. Built with precision-machined stainless steel and next-generation tubing that resists skin oils and alcohol, it offers durability and dependable performance. Snap-tight, soft-sealing eartips provide a comfortable fit and acoustic seal, and the stem includes an open side indicator.
