3M Littmann Classic III Stethoscope for Added Comfort, Flexibility and Cleanability, Stainless Steel Chestpiece, More Than 2X as Loud

The Littmann Classic III is used as a diagnostic aid during physical assessment. It is suitable for listening to heart, lung, and bowel sounds in both adult and pediatric contexts, making it a versatile tool for nurses, physicians, students, and other healthcare professionals.

The double-sided chestpiece has an adult side and a pediatric side. The adult side is used for standard assessment, while the smaller pediatric side is used for assessing children or for accessing difficult-to-reach areas.

Tunable diaphragms allow you to hear both low-frequency and high-frequency sounds without flipping the chestpiece. Simply apply light pressure to hear low-frequency sounds (such as heart murmurs) and firm pressure to hear high-frequency sounds (such as breath sounds). Both sides of the Classic III chestpiece feature tunable diaphragms.

Littmann rates its stethoscopes on a scale of 1–10 based on acoustic performance. The Classic III scores 7/10, placing it in the mid-to-high range — suitable for most clinical settings. Higher-rated models (such as the Cardiology IV) are designed for more specialized cardiac assessment.

The tubing is 69 cm (27.2") long — a standard length that provides a comfortable reach between the chestpiece and the clinician's ears during assessment.

The chestpiece has a stainless steel finish, providing durability and a professional appearance. Stainless steel is also easy to clean and disinfect between uses.

The single-piece diaphragm replaces the traditional separate diaphragm and rim design. This makes it easier to attach and remove, and easier to clean because there are no gaps or seams where bacteria can accumulate.

Simply squeeze the eartubes together to tighten the fit or pull them apart to loosen. The anatomically designed headset is angled to direct sound into the ear canal for optimal acoustic performance.

The Littmann Classic III comes with a 5-year warranty that covers free repair of any manufacturing or material defects. This reflects the quality and durability of the Littmann brand.

Wipe the chestpiece and tubing with a damp cloth and mild soap or 70% isopropyl alcohol wipes. Do not immerse in liquid or use harsh solvents. Clean the eartips regularly and replace them if they become worn. Avoid exposing the tubing to extreme heat or direct sunlight for extended periods.
