Why MDF Instruments


Our medical instruments have been engineered, since 1971, for optimal performance in every medical discipline, including cardiology, nursing, pediatrics, emergency medicine, veterinary, etc.


You are unique and so is your work. Our MOD initiative allows you to design the stethoscope that fits you because we believe the more “you” you can be, the better “us” we will become.


Lifesaving will last a life time and we promise to be with you through it all. Every MDF instrument is created to be highly durable but with all hard work tools eventually begin to wear. That’s why every MDF instrument comes with a lifetime warranty and Free-Parts-For-Life.


Everyone should have the right to be healthy. For medically underserved communities where we find this lacking we provide medical equipment to missions and volunteers who share our dream of global wellness.
