3M™ Littmann® Stethoscope Spare Parts Kit, Master Cardiology™, Gray, 40018

3M Littmann Stethoscopes offers the high quality that medical professionals expect, and each replacement part and accessory meets the same demanding standards. Conveniently packaged in kits that correspond to our stethoscope models, Littmann stethoscope replacement parts and accessories make repairs simple. Each item is carefully manufactured to work seamlessly with existing equipment. The 3M Littmann Stethoscope Spare Parts Kit – Gray, Compatible with Master Cardiology, Includes Snap Tight Soft-Sealing Small Eartips, Tunable Diaphragm & Rim, 40018 contains a gray rim and tunable diaphragm for 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. 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.
