Stethoscope Tips

How to Find Your Stethoscope's Serial Number

To find your MDF Instruments® stethoscope serial number look for seven characters printed on the stethoscope chestpiece. This should be a letter followed by a six digit number. Some models may vary with two letters and 6 or 7 numbers. 

Still Can't find it?
On the MDF797T and some MDF797 Stainless steel models have a hidden serial number. The serial number is not the 490-002 number on the diaphragm where the MDF logo is.  Please unscrew the other side which is the bell piece of the chestpiece to see the serial number on the chestpiece. Please note the serial number is not on the detachable attachment pieces. 
For the 797X unscrew the chest piece to find the serial number. For the 767X you can find the serial number in the side of the  middle barrel.
