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. US PAT 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. Why is the MD One chestpiece made of stainless steel? Stainless steel is dense and durable. The MD One chestpiece is crafted from stainless steel chosen for its acoustic properties and polished to a jewelry-grade finish to hold up to daily use in clinic, on rounds and in the ED. 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.

Stethoscope works and looks amazing
Color: RoseGold - White
First MDF stethoscope. Very nice material and strength. Does comfortably around my neck. Color is awesome. Works better than my other stethoscope. I can hear better and my hearing has diminished. Not heavy. Very versatile. The cost was so nice, low cost but very good stethoscope. Will buy MDF again.

Listen to your Heart-Talk.
Color: RoseGold - White
You enjoy quality craftsmanship and materials, when you touch it and feel its weight. The appearance is striking. The audio is superb. It should last a lifetime. I’ve had atrial fibrillation for two decades. I want to listen to my heart on a regular basis for my own personal meditation. The results have been surprisingly therapeutic. It’s an extension of the notion of “Know Thyself.” I plan to leave instructions to gift it to a nurse, when I no longer have a use for it. It’s a beautiful work of art. ... show more

Great quality MDF
Color: Silver - Burgandy
My son is an FDNY paramedic, and I bought him a littman and after he lost it 10 years ago I gifted him with and MDF, He loves the MDF so much more, and so this has been his 3rd and always have been MDF. Great quality, excellent durability, value for your money, accessories are included, and the over appearance is nice. MDF stethoscope is the way to go. A gift very much appreciated ... show more

Best purchase for me!
Color: All Black
I'm not a pro at all. I'm a student. I was told to purchase another popular brand and was having difficulty with it. (Blood pressure) So I decided to try this one. It's made a huge difference. The tube is slightly longer. Which I like. It's less expensive. I can hear the korotkoff sounds alot better. Slightly heavier than my other one. I cannot judge true quality yet since I'm new to using one, but it feels like it will hold up very well. I purchased the all black one and I love it. The black really shines right now. I know that MDF is the company I will be purchasing from and I will recommend for anyone in my program. ... show more

Decent for general use.
Color: All Black
This is a good all-around General use use stethoscope. It’s definitely not a Litman but it gets the job done for most tasks. I bought this one mainly just to keep in the house as a backup. It works perfectly fine for taking blood pressure or listening to lung sounds. It comes with several different squishy earbuds, which is nice as I have small ear canals so you do get options. The ear tips are easy to pop on and off and to replace as needed. The diaphragm and the bell all seem to be well-made and also comes with several replacement parts for that as well. The tubing is just the right length and overall the build quality is quite nice. Now it doesn’t have the same quality as my cardiology three which I use for work but for just generally having a back up and just one at the house for us to use for the family, this works great. I wouldn’t say that would be great in an EMS setting simply because The noise reduction is not as good as some of the higher end models and I can definitely still hear a good bit of road noise or other sounds from the environment. if you just need a good basic every day stethoscope for general tasks such as blood pressures or lung sounds or bowel sounds this will work great This will perform better than anything you purchase at Walmart and it definitely has better sound quality than a Sprague style or those cheapie little ones they market as nurse scopes here on Amazon. You don’t need to break the bank to get a decent quality Stethoscope. I would definitely recommend this. ... show more
