duplex® stethoscope

The duplex® is a traditional double-headed stethoscope designed for routine clinical
examinations. It is available with either a chrome-plated brass chest piece or a lightweight aluminium option. The design supports clear acoustic transmission across standard clinical frequency ranges and is suitable for general practice, outpatient settings, and tenders
requiring legacy specifications.

Product comparison

What is the difference between duplex® 2.0 and duplex® stethoscope?

  • duplex® 2.0 uses an integrated spring within the binaural, whereas the legacy duplex® uses an external spring design
  • duplex® 2.0 is equipped with pivotable ear tips, while the legacy duplex® has fixed ear tips
  • duplex® 2.0 includes a clear side indicator to show whether the membrane or bell is active
  • The aluminium duplex® 2.0 model is lighter at 97 g, compared with 104 g for the legacy duplex®
We continue to offer the legacy duplex® stethoscope because:
  • It remains an affordable alternative to duplex® 2.0
  • It is suitable for tender specifications or markets where legacy models are required
