Two-sided chest piece with tuneable diaphragms on both the adult and paediatric sides Single-piece tuneable diaphragm is easy to attach and easier to clean because its surface is smooth without crevices Paediatric 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 tuneable diaphragm is useful for paediatric, small, or thin patients 3M Littmann 5623 Classic III Stethoscope, Caribbean Blue
