NOTES on cleaning
1. Avoid disassembling the microscope!
Because it is a precise optical instrument, do not disassem-
ble the microscope casually. That may cause serious dama-
ge to its performance. Do not disassemble the objectives.
2. Avoid contamination!
You should make sure that dust or moisture do not get
in contact with your microscope. Avoid touching optical
surfaces with your fingers! If dust or dirt nevertheless have
gotten onto your microscope, or the accessories, remove it
as described below.
3. Cleaning non-optical parts:
Disconnect the plug from mains socket before cleaning
non-optical parts of the microscope (e. g. the body or the
stage). First, remove dust or dirt from your microscope, or
accessories, using a soft brush. Then clean the dirty area
with a soft, lint-free cloth; the cloth may be moistened with
a mild detergent solution. Be sure that the microscope is
dry before using. For cleaning the painted parts or plastic
components, do NOT use organic solvents such as alcohol,
ether, acetone, xylene or other thinner etc.!
4. Cleaning optical parts:
In order to enhance the optical quality, the lenses of eye-
pieces or objectives are coated. They should not be wiped
because dry dirt or dust may scratch the coating. It is best
to remove the parts to be cleaned from the body prior to
cleaning. Always blow loose dust away first. Use lens tissue
of good quality or soft fabric moistened with a small amount
of pure alcohol (available in the pharmacy); wipe the lens
surface clean.
5. Cleaning the oil immersion lens:
After working with oil immersion, the immersion oil should
be removed from the lens of the 100x objective at the end
of each workday. In order to do this, use a lens tissue moi-
stened with a small amount of pure alcohol (available in the
pharmacy). Don't forget to clean the preparation, too.
6. Storing the microscope:
After usage, cover the microscope with the dust cap (made
of plastic) and keep it at a dry place, away from mold. If it
is not used for a prolonged time, store the microscope and
accessories in their respective containers.
Remember:
A well maintained microscope will keep its optical quality
for years and thus maintain its value.

Technical data

Monocular head
Mechanical desk (with vernier alignment)
Eyepiece: DIN WF 10x
Objectives: DIN 4x / 10x / 40x / 60x or 100x (oil)
Magnification: 40x - 600x or 1000x
Illumination: rechargable battery LED
Technical alterations and errors excepted.
Aperture:
The numerical aperture (the unit of measurement for the
resolution factor of the objectives) is engraved beside the
magnification-sign on the objectives.
The magnification for microscopes
is calculated by formula:
Eyepiece magnification x objective magnification factor
= total magnification
Example: 10x eyepiece x 100x lens
= 1000x total magnification
Disposal
