MDF 747XP DELUXE DUAL HEAD Stethoscope for internal medicine, purple (MDF8)

Extremely light. 
A very light stethoscope intended for all healthcare workers. The adjustable lyre is made of chrome-plated brass. Reversible head. The extremely light double-sided head made of anodized aluminum and chrome-plated brass provides good acoustic parameters and traditional methods of auscultation through the diaphragm and funnel. Innovative technologies. 
The diaphragm is made of ultra-sensitive sound-amplifying fiber. Perfect tightness of the membrane is ensured by the membrane retention ring, which creates optimal amplification and a high frequency of heart and lung transmission at frequencies of 100 to 1000 Hz. A very large funnel with a non-cooling ring provides excellent acoustic transmission and isolation of low frequency sounds. The membrane is convex with a durable support ring made of non-cooling PVC material for greater patient comfort.
