Trust the Littmann brand to bring you acoustical superiority, innovative design and exceptional performance. The Classic II stethoscope offers both adult and pediatric sides with tunable diaphragms. The single-piece tunable diaphragm is easy to attach, and is easier to clean, with a smooth, crevice-free surface. The 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 and is less likely to pick up stains. Small tunable diaphragm can be useful for pediatric, small, or thin patients; around bandages; and for carotid assessment. No natural rubber latex or phthalate plasticizers are used in the tubing or any other component. 5 Year warranty.
