Cleaning/Maintenance/Transport; Technical Data; Disposal - Bresser SCIENCE TRM-301 Instruction Manual

9. CLEANING/MAINTENANCE/TRANSPORT

During long breaks, and before all maintenance and cleaning work, disconnect the power supply by unplugging the mains
plug.
Remove all interchangeable optical elements (e.g. objectives, eyepieces, etc.) before cleaning.
The nosepiece, the coarse/fine focusing mechanism and the condenser are precisely designed and calibrated to work
together. Please avoid dismantling the components. This impairs the performance of the microscope.
CLEANING
Lens cleaning:
Wipe the lenses with a lens cleaning cloth or a soft cloth moistened with a small amount of alcohol or alcohol/ether
mixture. Clean the immersion oil from the 100x immersion objective and the condenser lens after use.
Cleaning of microscope and optical elements:
Only clean the outside of the microscope with a dry cloth.
First, blow loose dust off the lens surfaces.
Use high quality lens cleaning towels or soft cloth and moisten it with a little bit of pure alcohol (available in a drug store).
Gently wipe the lens surface in a circular motion from the centre to the edge of the lens, applying a small amount of
pressure.
WARNING: Do not use organic solvents (e.g. alcohol, ether, acetone, xylene or other thinners) to clean painted or
plastic parts!
WARNING: Alcohol is highly flammable.
WARNING: To avoid damaging the electronics, do not use any cleaning fluid.
Cleaning the 100x oil objective/condenser lens
The immersion oil should be removed from the objective/condenser lens at the end of each working day.
Clean the 100x objective (oil) and the condenser lens by dabbing off the oil with a soft baby paper towel (lotion-free). If you
use the 100x objective with oil immersion on a regular basis, it is sufficient to clean it once a week with a solution of 70 %
ethanol or isopropanol (to prepare such a solution, use p.A or standard pharmacy alcohol and double-distilled water).
Dust protection:
When not in use, cover the microscope with the dust cover and place it in a dry and mould-free place. We recommend
storing all objectives and eyepieces in a closed container with desiccant.
Transport:
Remove all loose components and the specimen from the XY stage. Only use the original packaging for transportation.
