Instrument care
Maintenance of the Axioscope is limited to the following activities:
•
Turn the instrument off after each use and cover it with the appropriate protection cover (dust and
humidity protection).
•
Do not use or keep the instrument in a humid environment (maximum humidity
≤
75%).
•
Cover any open tubes with the dust protection caps.
•
Remove dust or dirt from the visible optical surfaces by using a soft brush, blower brush, cotton swab,
optical paper or cotton cloth.
•
Remove water-soluble stains (coffee, soft drinks, etc.) with a dust free cotton cloth, which can be
slightly moistened with water only or with a mild detergent diluted with water.
•
Remove oil or grease stains (immersion oil, fingerprints) with a cotton swab or a dust- and lint-free
free cotton cloth and the special optical cleanser L.
This cleanser is made of 90% petroleum ether by volume and 10% isopropyl alcohol (IPA) by volume.
The ingredients are also known by the following names:
Petroleum ether: surgical spirit, benzine
Isopropyl alcohol: 2-propyl alcohol,
dimethylcarbinol,
2-hydroxypropane.
Clean the optical surfaces in a circular motion going from the middle towards the edge. Do not press too
hard.
ATTENTION
Do not use acetone to clean the lenses of the Pol condensers.
Please comply with the following instructions if you are going to use the microscope in a hot and humid
climate:
•
Keep the instrument in a bright, dry and well-aired room; humidity
≤
75%; especially delicate parts
like objectives and eyepieces should be kept in special dry closets.
Precision optical instruments may be damaged by mold if they are kept and used under the following
conditions:
−
If the relative humidity > 75% longer than three days at a temperature of b15
°
C and
+35
°
C.
−
If they are set up in dark rooms without sufficient ventilation.
−
If there are dust and finger prints on optical surfaces.
