Cleaning the Connectors
Warning: It is recommended to avoid the use of cleaning solutions to avoid corrosion. If a wet
cleaning is required, use distilled water. Make sure that only the connectors touch the liquid;
do not submerge the miniature preamplifier or the cable. Otherwise, you can fatally damage
the electronics.
Clean the connectors with 70 % alcohol and cotton swabs from time to time.
If this does not provide satisfying results, insert only the connectors into a small beaker with
acetone or alcohol and treat them in an ultrasonic bath for 10 to 20 s. Air-dry the miniature
preamplifier for about 5 min before use.
You can also clean the connectors with distilled water in an ultra sonic bath. Dry the
connectors with compressed air immediately after sonication and let the amplifier air dry for
at least 6 h before use.
Sterilization
Warning: Do
not
autoclave or sterilize
miniature preamplifiers by high heat
(above 70 °C)
or
vapor
. The resin is not heat-stable and may deform under heat. Vapor can lead to a corrosion
of the electronics.
Miniature preamplifiers can be sterilized with standard methods that are not based on high heat
or vapor, for example, with 70 % ethanol, UV-light, or by thermal sterilization in an oven at
56 °C with an incubation time of 8 hours.
