3M Littmann Classic III Stethoscope, Matte Chestpiece, Black Tube, 27 inch, 5803

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.
