3M Littmann Stethoscope Spare Parts Kit Master Cardiology Black

3M Littmann® Stethoscope Spare Parts Kit for the Master Cardiology™ Stethoscope contains a black rim and tunable diaphragm for chestpiece, in addition to two small (1/2"), black snap tight soft-sealing eartips. Tunable diaphragm technology 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. 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. Sold in one convenient package. Suggested application: Replacement of eartips, and the tunable diaphragms on Master Cardiology™ stethoscopes.
