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
chemist's shop). Don't forget to clean the preparation, too.
6. When not in use:
After usage, cover the microscope with the dust cap (made
of plastic) and place it where it is dry and mouldless. In
the case of non-use for a longer time, you should stow the
microscope and the accessories in their correct containers
again. We suggest the storage of all objectives and eyepi-
eces in a closed container with drying agent.
Remember: A well maintained microscope will keep its
optical quality for years and thus maintain its value.

57-22100: Binocular head
57-23100: Trinocular head
Mechanical desk (with vernier alignment)
Eyepieces: DIN WF 10x
Objectives: DIN 4x / 10x / 40x / 100x
Magnification: 40x -1000x
Illumination: LED
Accessories: Immersion oil, fuse
10. Aperture:
The numerical aperture (the unit of measurement for the reso-
lution factor of the objectives) is engraved beside the magnifi-
cation sign on the objectives.
11. The magnification for microscopes
It is calculated by the formula:
Eyepiece magnification x objective magnification
= total magnification
Example:
10x-eyepiece x 100x-lens = 1000x total magnification
