3M Littmann Spare Parts Kit – Classic III Stethoscope (Black)

3M Littmann Stethoscope Spare Parts Kit (Model 40016, Black) – for Classic III and Cardiology IV Stethoscopes.

Kit Includes:
– One black single-piece tunable diaphragm for the adult side of the chestpiece
– One black single-piece tunable diaphragm for the pediatric side of the chestpiece
– One non-chill bell sleeve
– Two small (1/2 inch) black Snap Tight Soft-Sealing Eartips

Tunable diaphragm technology (a 3M invention) lets clinicians hear different frequency sounds by adjusting pressure on the chestpiece – light pressure for low frequency sounds, firmer pressure for higher frequency sounds. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Genuine 3M Littmann product.
