LIGHT & STRONG
I Am Titanium
Titanium is 45% lighter than stainless steel and has the highest strength-to-density ratio of any metallic element. This is why brilliant engineers use it in race cars, space shuttles, and now stethoscopes.
LIGHTWEIGHT EXQUISITE SOUND
Constructed from lightweight titanium, the MDF® ProCardial® Titanium Stethoscope delivers accurate auscultation of heart, lung, and Korotkoff sounds with acoustic integrity and clarity. Compared to its 9.6oz stainless steel counterpart, our titanium ProCardial® weighs in at only 4.9oz. Imagine what that feels like over a 12 hour shift. With its extra-deep, cone-shaped bell and ultrasensitive diaphragm, this cardiology stethoscope detects the entire frequency range required by cardiologists.

The Look of Sound
A concert of colorful chestpieces and headsets to choose from.
Stand out in a sea of scrubs.
Sound Check 1-2-3
The ProCardial® provides flexibility in assessment, quickly converting to an adult, pediatric (797DDT) or infant (797CCT) stethoscope with its patented screw-on convertible chestpiece.

TRUE BELL & TRUE DIAPHRAGM
Take the guesswork out of auscultation with our True Bell & True Diaphragm dual-head chestpiece. The bell side focuses on low frequency sounds (20Hz-100Hz) while the Ultra-sensitive Diaphragm handles high frequencies (100Hz-1000Hz).
With our patented Titanium SoundTight™ Glide-Lock-System™ (GLS), we’ve minimized sound loss of this crucial indexing mechanism. Simply push, turn, and the GLS will lock itself into place.

Sound as a Bell
Our deeper, cone-shaped bell amasses specific low frequency heart sounds, which can often be difficult to distinguish.
C34 ACOUSTIC TUBING
We took the engineering principles used in concert halls and applied it to our stethoscopes. Flat walls create echoes which is why deeply cut baffles are used to reduce sound wave refraction. Using this theory our new C34 tubing has 34 channels etched inside the tube to direct clear and precise sound waves from your patient to your ears.
US PATENT PENDING
DENSER, LONGER TUBING
Our flexible, latex-free tubing is thicker and longer than others to block out external noises, and provide a safer distance between you and your patient.
Our patented ErgonoMax™ headset is pre-angled and tension adjustable, allowing for a tailored fit. The dual-leaf spring adds a second layer of durability, ensuring the structural integrity of the headset and prevents breaking when tension is increased.
Pat No. ZL 200820155127.0
Our new patent pending STEnT™, permanently attached to the dual-leaf spring, keeps the spring from blocking the opening of the Acoustic Pyramid Chamber™. This ensures a clear and open channel at this important junction.

Safe & Sound
Our patented SafetyLock™ prevents accidental puncturing of the eardrum from loose eartips coming off during your practice.

CLEAR SILICONE EARTIPS
Our ComfortSeal™ eartips provide you with the perfect fit. All MDF® stethoscopes come with 3 sizes of eartips in small, medium, and large. Pliable silicone material allows the eartip to compress slightly creating a better sound seal.
Laser engrave the chestpiece with a message of your choice, making it easy to identify and personalize for you, or a loved one.
With our Free-Parts-For-Life Program, request replacement eartips, diaphragms, non-chill rings, retaining rings, and name tags anytime online and we will ship them out to you for free.
With You For Life
For half a century, our master craftsmen have meticulously created exquisite stethoscopes for healthcare professionals, and we will continue this fanatical discipline for lifetimes to come. We will be here.
