4.1 Instrument care
Care of the Axioskop 40 / Axioskop 40 FL is limited to the following operations:
•
Switch off the instrument each time after use and place the instrument cover on it to protect it from
dust and humidity.
•
Do not set up the instrument in a humid room; maximum humidity < 85%.
•
Cover the open tubes with dust caps.
•
Dust and loose dirt on visible optical surfaces should be removed with a brush, bulb, cotton swab,
optical paper or cotton cloth.
•
Remove water-soluble dirt (coffee, cola, etc.) by blowing on it and wiping it off with a lint-free cotton
cloth or a damp cloth. You can use a mild cleaner in the water.
•
To remove stubborn, oily dirt, e.g. fingerprints or traces of grease and immersion oil, use a cotton
swab or lint-free cotton cloth and the optics cleaning solution L. The cleaning solution comprises 90
Vol% gasoline and 10 Vol% isopropanol (IPA). The individual components are also known as:
Gasoline:
Medical alcohol, Petrolether
Isopropanol: 2-Propanol,
Dimethylcarbinol,
2-Hydroxypropan
Clean the optical surface by polishing in circles starting in the middle and moving to the edges (only use
slight pressure).
When using the microscope in humid climatic zones, proceed as follows:
•
Store the instrument in bright, dry and well-ventilated rooms with humidity not in excess of 85 %;
optical components and accessories that are particularly susceptible to fungus growth, e.g. objectives
and eyepieces, should be stored in a dry closet.
The risk of fungus growth on opto-mechanical instruments invariably exists in the following conditions:
−
Relative humidity in excess of 75 % and temperatures b15 °C and +35 °C for more than
three days.
−
Installation in dark rooms without air ventilation.
−
Dust deposits and fingerprints on optical surfaces.
