The Riester Duplex® 2.0 is a professional dual-head stethoscope developed for reliable auscultation in general clinical practice.
Its precision double chest-piece is made of stainless steel, providing a robust construction combined with an acoustic system designed for auscultation across all frequency ranges.
The stethoscope incorporates a 44 mm (1.7 in) special membrane with non-chill rims, improving patient comfort during examination by reducing the sensation of cold metal against the skin.
The anatomically shaped binaural incorporates an internal multiple spring system, allowing adjustment of contact pressure according to the user’s preference. The extra-soft, replaceable and pivotable ear-tips are designed to provide an effective seal within the ear canal while improving wearing comfort.
The total length is 74 cm (29.1 in), providing practical reach during routine clinical examinations.
The Duplex® 2.0 is latex-free and is supplied with useful replacement components, including one pair of replacement ear-tips, a replacement membrane, and a name plate.

⚠️ Weight Clarification
The supplied information mentions 350 g in one product-data field, but the detailed Riester specification states:
- Stainless-steel version: 151 g
- Aluminium version: 97 g
The pictured model appears to be the stainless-steel version, so 151 g is the appropriate specification to use for this product listing rather than 350 g.
🇩🇪 Made in Germany
The product information identifies the country of origin as Germany, and the packaging shown in the photographs also carries “made in Germany.”
⚕️ Clinical Note
The Duplex® 2.0 is an auscultation instrument used to listen to internal body sounds. It is not itself a diagnostic device that establishes a diagnosis independently.
Clinical findings obtained with a stethoscope should always be interpreted alongside the patient’s history, physical examination, vital signs, and appropriate investigations when indicated.
