3M Littmann Classic III Steth Ceil Blue 27

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
