1.8. Cleaning/maintenance/transport
Disconnect the device from the power supply by pulling the power plug when it is
not used or in case of longer interruption of operation and before starting any work
on maintenance and cleaning.
Disassemble optical elements (e.g.objective, eyepiece, etc.) before cleaning.
Be sure that the instrument is dry before using.
Do not use organic solvents (e.g. alcohol, ether, acetone, xylol or other dilutions)
to clean lacquered parts or plastic parts!
Alcohol is highly flammable.
To avoid damaging the electronics, do not use any cleaning fluid.
When using objects that present a potential risk of infection, all parts that have
come into contact with the object must be thoroughly cleaned.
The nosepiece, the coarse/fine focusing mechanism and the condenser are pre-
cisely designed and aligned. Please avoid dismantling the components. This affects
the performance of the microscope.
Transport: Please remove all loose parts and the object to be observed from the
stage. Only use the original packaging for transport.
Cleaning microscope body / optical elements
• Only use a dry cloth to clean the exterior of the device.
• Disassemble optical elements (e.g. objective, eyepiece, etc.) before cleaning.
• Blow away loose dust from the lens surfaces first.
• Use high quality lens cleaning towels or soft cloth and moisten it with a little bit of pure
alcohol (available in a drug store). Wipe the lens surface with it.
Cleaning the 100x immersion oil objective
• The immersion oil/ cedar oil should be removed from the lens at the end of each work-
day.
• Clean the 100x objective by dabbing off the oil with a soft baby paper tissue. When
the immersion lens is used regularly, wet clean the lens only once a week, Use a solu-
tion of 70% ethanol or isopropanol (use p.a. or pharmacy grade alcohol and double
distilled water to make such a solution).
