3M Littmann Stethoscope Spare Parts Kit for the Lightweight II S.E. stethoscope contains a black rim and tunable diaphragm and a non-chill sleeve for the chestpiece, in addition to two large 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. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill diaphragm provides patient comfort. 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.
