## Description

Since 1971, we have invested our passion and fearlessness to improve quality of life for medical professionals and their patients .
MDF Instruments are super-duty, high-performance medical tools that meet the toughest requirements of precision and accuracy.
With over 50,000 donations to 200 medical missions, we are a company dedicated to serving the people who serve people.
We believe in innovation and aesthetics, that translate a strong identity of design and style, to make our products uniquely you.
We invest in customer experience, not to Up-Sell but to Up-Serve our medical heroes to make their time with us exceptional.
Our motivation is to leave a legacy by doing what is right and good and not by profit and publicity.
“Fear” is our “F” word. We don’t allow our ego to hold us back from reinventing ourselves and pushing new boundaries.
The courage to persevere through discomfort for the sake of doing good. We are comfortable being uncomfortable.
Create and deliver the unexpected; we neither accept nor force-feed average.
We're dedicated to providing the highest quality Stethoscopes, Sphygmomanometers, Reflex Hammers, Pen Lights, Otoscopes & Medical Bags.
Our customers are always on the go and often travel for work, which is why we offer bags and cases designed for medical professionals.
Extra-large bell isolates low-frequency sounds (20–100 Hz) like murmurs. Ultra-sensitive diaphragm captures 100–1000 Hz breath and bowel sounds
Latex-free tubing is thicker to reduce ambient noise and longer to give you more working distance from your patient during auscultation
Patented headset adjusts for a comfortable fit and a dual-leaf spring adds strength so the headset holds its shape through daily clinical use
The patented Acoustic Pyramid Chamber keeps the tubing from kinking or compressing as you move, so the sound channel stays clear and open
Patented SafetyLock adaptors lock each eartip onto the headset, so tips stay securely in place during exams instead of coming loose
Soft, pliable silicone eartips in small, medium and large create a secure acoustic seal for a comfortable, custom fit on long shifts
Request replacement eartips, diaphragms, non-chill rings, retaining rings and name tags anytime, and MDF ships them to you free of charge
For over 55 years MDF craftsmen have hand-finished our stethoscopes, each one backed by our forever craftsmanship promise
Can I use the MD One for manual blood pressures in nursing school and clinicals?
Yes. The MD One is designed to transmit Korotkoff sounds clearly for manual blood pressure checks, along with heart, lung and bowel sounds, so it supports you from skills lab through clinicals and beyond.
Do I need a bell, or is a diaphragm-only stethoscope enough for med school?
Having both helps. The MD One true bell is designed for low-frequency sounds and the true diaphragm for high-frequency sounds, and a fully rotating stem lets you switch between them during a full exam.
Is the MD One a little heavier because it is made of stainless steel?
Yes, by design. Unlike others, the MD One is 100% stainless steel, has a wider chestpiece, longer & denser tubing, and the ErgonoMax headset has 2 springs vs. one.  All built for clear sound, durability, noise blocking and comfort on long shifts.
Will the MD One help me hear heart and lung sounds on a noisy unit?
The MD One uses long, dense, latex-free tubing designed to help block out ambient noise, so heart and lung sounds come through with clarity even when the unit is busy.
What is the patented Acoustic Pyramid Chamber on the MD One?
It is a patented MDF chamber design that helps prevent the tubing from kinking, so sound keeps traveling freely from the chestpiece to your ears whether the stethoscope is around your neck or in your pocket.
Is the MD One comfortable enough to wear for a full 12-hour shift?
It is built for long shifts. The patented ErgonoMax headset is pre-angled for a natural fit and tension-adjustable with dual-leaf spring construction, so it stays secure in your ears without pinching.
What eartip sizes come with the MD One if my ears are small or sensitive?
Three pairs of soft silicone ComfortSeal eartips are included in small, medium and large. Try each size to find a snug seal that blocks outside noise and stays comfortable through long clinical days.
What keeps the eartips from coming off the MD One headset during use?
The patented SafetyLock eartip adaptors are designed to hold the eartips securely on the headset, helping keep them from slipping off while you listen. It is a non-invasive design focused on user safety.
Is the MD One a latex-free stethoscope?
Yes. The MD One is latex-free, including its tubing, making it a fit for latex-free care settings and for clinicians who prefer to avoid latex in the equipment they wear all day.
How durable is the MD One for years of daily clinical use?
The MD One is handcrafted, a stethoscope maker since 1971, using stainless steel and a dual-leaf spring headset built for durability, so it holds up to daily rounds, transport and years of wear.  MDF offers lifetime coverage and free parts for life.
What happens when my eartips or diaphragm wear out?
MDF's Free-Parts-For-Life program provides replacement eartips, diaphragms, retaining rings, non-chill rings and ID tags at no cost, so normal wear does not mean replacing your stethoscope.
Does MDF have a contact phone number?
Yes, MDF is located in the United States and has a US phone number. Call Monday through Friday from 8am to 5pm EST to speak with live MDF in-house Client Experience Representatives who are fluent in English and Spanish.
Is the MD One worth buying as an MS1, or should I wait until residency?
It is built to go the distance. A stainless steel dual head design, a spare diaphragm in the box and replacement parts from MDF help one MD One carry you from MS1 through rotations and into residency.
What comes in the box with the MD One stethoscope?
You get the MD One adult stethoscope, three pairs of ComfortSeal eartips in small, medium and large, a spare diaphragm and an ID tag, so you are ready for skills lab and clinicals right away.
Is the MD One a thoughtful gift for a nursing or med school graduate?
Yes. It is a stainless steel dual head stethoscope offered in over 20 color variations, with an ID tag and extra eartips included, a practical gift for white coat ceremonies, pinning and graduations.
MDF Instruments’ Crafting Wellness program donates stethoscopes, blood pressure monitors and other medical instruments to medical missions and nonprofit organizations worldwide, equipping healthcare teams to care for underserved communities.

## Questions & Answers

**Q: does the white/rose gold stethoscope get dirty from your skin/the environment? and if so, does it clean off easy?**
A: I have had the white/rose gold stethoscope for almost 4 years, it has great sound and is comfortable, but I will never buy a white one again because it does pick up some of the color of the scrubs I wear and ad is beginning to yellow on the neck area of the tubing.

**Q: Can the Rose Gold be cleaned with alcohol without damaging it?**
A: Yes, you can clean the rose gold with 70% isopropyl alcohol pads, and it will not damage the rose gold.  If anything tarnishes, please reach out to our customer service department as tarnishing would be covered under our Lifetime Warranty program.

**Q: I am a third year veterinary student, and this will be the first stethoscope I will buy.. I am just seeing how well it woks for veterinary students..?**
A: The MD One stethoscope is a versatile stethoscope with a great Lifetime Warranty program, so if you are experiencing any manufacturers issues, we will repair or replace the parts.  We also offer Free Parts for Life so if you need new ear tips, a diaphragm or retaining ring, please reach out to us at 818-377-5647.

**Q: Where are these made? Thanks.**
A: Thanks for your good question. Where are our products from? That is a complex question to answer because they are conceived and designed in our headquarters in Los Angeles. Sometimes the best materials, components and manufacturing can't be found in one country. That's why we scour the world for the best possible materials and components from countries such as Taiwan, Japan, Germany, etc. and the final assembly is handcrafted to meticulous standards and jewelry grade finish by our artisan craftsman (some with over 30 years of experience) in our dedicated facility in Shanghai to be sold in over 85 countries all over the world. All of this said, this is simply how we are able to deliver the best (listen to what our customers have to say - check out our excellent reviews). Thanks in advance for your business!
