The flagship of the collection, the Littmann Master Cardiology is engineered for the highest acoustic sensitivity Littmann offers — ideal for detecting faint heart murmurs and subtle sounds. Its handcrafted, single-sided tunable diaphragm lets clinicians shift between low and high frequencies simply by adjusting pressure, with no need to flip the chestpiece. Available in Black (2160, 2161), Burgundy (2163), Navy Blue (2164), and Plum (2167) with a 27-inch, latex-free tube and soft-sealing eartips, these are built for cardiologists and clinicians who need to hear everything.

For infection prevention teams, the Conmed Channel Master endoscopic cleaning brush (000639) reaches internal channels during scope reprocessing. Laundry and housekeeping departments rely on Diversey Clax Master 100, an unscented liquid detergent in 1-gallon jugs and 5-gallon pails for high-volume institutional wash cycles. Rehab and sports-medicine settings use DJO Flex-Master elastic bandages with clip closures — available sterile (6 in. x 5.5 yd) and non-sterile (6 in. x 11 yd) in a cotton/rubber blend that minimizes moisture retention and allergic reaction. Patient-safety planners will also find the battery-powered Bathmaster Sonaris bath lift, which reclines up to 40 degrees to ease independent, seated bathing.
