Designed for your little patients. Stainless steel chestpieces are optimally sized for pediatric and infant auscultation. The pediatric stethoscope features a 1-inch bell and the infant stethoscope has a 3/4-inch bell for an easier chestwall seal. The 3M™ Littmann™ Classic II Pediatric and Infant stethoscopes are designed for long-lasting durability. These precision instruments are also designed to maximize the comfort of both patient and professional. Benefits: The solid stainless steel chestpieces on the 3M™ Littmann™ Classic II Pediatric and Infant Stethoscopes are optimally sized for your little patients. The small diaphragms conform to the contours of pediatric and infant bodies. The snap-on rim will not rust or corrode. And unlike threaded rims, it will not come loose or fall off. There is also a crack-resistant, reinforced yoke that allows you to fold the scope easily into your pocket without kinking or breaking. The internal double-leaf binaural spring helps assure a long life and allows easy adjustment of eartube tension. The lightweight eartubes are durable and abrasion-resistant. They feature a nonchill rim on both the diaphragm and bell, so there's no need to warm them up. Plus, each stethoscope comes with patented 3M™ Littmann™ Snap-tight Soft-sealing Eartips designed to assure an excellent acoustical seal in the ear canal and maximize comfort.
