The 3M™ Littmann® Cardiology S.T.C. Stethoscope combines a unique, ergonomic design and precision craftsmanship to provide a superb listening experience. The distinctive Soft-Touch Chestpiece (S.T.C.) allows you to maintain a sure grip while easily moving between auscultation sites.

Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two-sided models, there’s no need to turn over and reposition 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 rim provides patient comfort.

Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. 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.

Resilient next-generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stethoscope life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next-generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. And, to play its part in the protection of human health and the environment, the next-generation tubing does not contain phthalate plasticizers.

The Cardiology S.T.C. stethoscope is made in the USA for consistent quality. It comes complete with large and small soft-sealing eartips, large firm eartips, and instructions.

  • Broadly used in a large variety of health care settings as a diagnostic tool as part of the physical assessment of heart, lung and bowel sounds. A perfect stethoscope for cardiologists, critical care nurses, EMTs, ER doctors, general practitioners, medical students, respiratory specialists.
