3M LITTMANN Classic III & Cardiology IV Stethoscope Spare Parts Kit - Gray REF 40017

3M™ Littmann® Stethoscope Spare Parts Kit for the Classic III™ Stethoscope and Cardiology IV Stethoscope contains a gray single piece tunable diaphragm for both the adult and pediatric sides of the chestpiece, in addition to two small (1/2 inch), gray Snap Tight Soft-Sealing Eartips.

Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds, press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on both adult and pediatric patients.

Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.
