[1] MDF instruments is one of the largest and best regarded manufacturing brand in North America, The MDF instrument range includes not only a comprehensive range of stethoscopes but other diagnostic testing and medical equipment including sphygmomanometers, reflex hammers and other clinic diagnostics.

The manufacturing quality and design of the [2] MDF medical equipment range is second to none within the price range of the model line up. A basic single tube lite stethoscope such as the [3] MDF 727 stethoscope range are compact models commonly found on wards and clinic as stock items for general use. The tube thickness of these smaller units is considerably thinner than the comparable [4] MDF 747 stethoscope or [5] MDF 777 stethoscope which are much better suited to clinical auscultation of heart and respiratory sounds. The head sets are also smaller on 727 stethoscopes and the ear tips are firm and non fitting. This is fine for general clinic use including BP ausculation as the sound quality is perfectly adequate and the stethoscopes are not going to be worn for long periods. The firm vinyl ear tips can also be sterilised when in general use.

For Doctors and nurse practitioners requiring a better quality but still pocket size stethoscope then the entry level should be the [6] MDF 747XP stethoscope.

Not full size but with great quality tubing and full size adult chest piece and head set the 747XP stethoscope is superb value for money and will remain perfectly adequate for most hospital doctor and GP general examination needs. The construction is first rate and the stethoscope is available in a wide range of tube colours and comes with name tags and spares included.

Next up in the mdf range is the MDF 777 stethoscope, full size doctors stethoscope.

The manufacturing and finish are superb as is the presentation of the full retail box packaging. The [7] MDF 777 stethoscope is the staple ER room choice in the states and is every bit as good as its comparable leading stethoscope brands such as the [8] Littmann Classic II SE and [9] Spirit AW stethoscope
