3M Littmann Classic III Stethoscope Gray Tube (5621)

Of all medical equipment, stethoscopes are the most familiar to patients. The temptation to experience stethoscope acoustic performance is almost irresistible, and only deference to the doctor keeps most people’s hands off. Devices that enhance perception of sound, sight, smell, taste and touch are greatly appreciated by medical practitioners, none more so than Littmann Stethoscopes that utilise the best of cutting-edge science and technology. Littmann innovations extend from function to form, including a vast choice of stethoscope colours such as the subdued but stylish 3M Littmann Classic III Stethoscope-Gray Tube (5621).

Style is important in today’s world where standing out from the pack is encouraged. The days of all-white hospital and medical attire are long gone, and individuality is now celebrated even in serious environments where saving lives is the priority. It’s understandable, as Littmann Stethoscopes have been developed and manufactured to last for many years of reliable service. A perusal or any reputable medical website will reveal a preference for quality Littmann Stethoscopes for nurses, doctors, medical students and other healthcare providers, with 3M Classic III Stethoscopes leading the way.

What are some Littmann Classic III benefits?

Versatility is an obvious Littmann trait worth exploring. The Classic III Stethoscopes contain multifunctional capacity achieved by decades of dedicated Littmann research and development. Superior acoustic sensitivity, comfort during prolonged use, ergonomically designed components and environmentally friendly materials are just a few reasons students, doctors, nurses and other healthcare specialists choose Littmann. Here are some more Littmann Classic III benefits.

How is Next generation tubing better?

As with every product and device there are always opportunities for improvement. Littmann have their finger on the pulse, allowing stethoscope development to evolve with the introduction of improved medical science, technology and materials. Next Generation Tubing is incredibly flexible, stain resistant and long-lasting, making it the perfect fit for Littmann Stethoscopes that are manufactured to provide consistent performance for years of reliable use. Next Generation Tubing does away with harmful rubber latex and phthalate plasticisers that react with sensitive skin and damage the environment. 3M Littmann Classic III Stethoscopes are lightweight and easily folded into a pocket, yet incredibly sturdy and reliable. Next Generation Tubing always looks good, being resistant to staining caused by skin oils, alcohol or other damaging substances.

What are the tuneable diaphragm advantages?

When using a 3M Littmann Classic III Stethoscope with tuneable diaphragm there is no need to lift and replace the chestpiece for auscultation of low and high frequencies. With a tuneable diaphragm the user simply adjusts the amount of pressure applied on the chestpiece. Light contact enables listening to low-frequency sounds (bell mode), while firmer pressure delivers high-frequency sounds (diaphragm mode). This adaptable convenience is a Littmann feature worth serious consideration for dedicated medical professionals and students who genuinely want the best for their patients.
