3M Littmann Master Cardiology Stethoscope, 27 in

The 3M Littmann Master Cardiology Stethoscope is an adult dual-lumen stethoscope with a 27 in (69 cm) overall length, a tunable diaphragm chestpiece, and tubing that carries two sound paths in one tube. Four tube colors — navy blue, black, plum, and burgundy — pair with a standard-finish chestpiece, and a fifth configuration is finished black throughout with a black plated chestpiece and eartubes. A rubber non-chill rim and diaphragm stay comfortable against the patient, and the stethoscope carries a seven-year warranty.
