Cleaning, Disinfection and Storage
Clean your stethoscope between exams using a 70% isopropyl alcohol
wipe or a disposable wipe with soap and water. A 2% bleach solution
may be used to disinfect your stethoscope; however, the tubing may
experience a slight discoloration after exposure to bleach. The tunable
diaphragms, nonchill bell sleeve and eartips may be removed for
thorough cleaning.
To remove the eartips from the headset, pull firmly. To assemble the
eartips, push the small side of the eartip firmly onto the eartube until
it snaps fully into place. Ensure all parts and surfaces are dry before
reassembly. Be sure the eartips are firmly attached to the headset
before inserting them into your ears.
Do not immerse your stethoscope in any liquid.
Do not subject your stethoscope to any sterilization process.
Avoid storing your stethoscope in extreme heat.
To prevent staining of stethoscope tubing, avoid contact with pens,
markers, newsprint, or other printed materials.
