Care
In this section
we will show you how to look after your microscope and how
to clean it.
We guarantee the quality.
You are working with a high-precision, high-performance
instrument.
We therefore guarantee the quality of each of our instruments.
Our guarantee covers all faults in materials and manufacture.
It does not, however, cover damage resulting from careless or
improper handling.
Please handle your valuable optical instrument with respect.
It will then fulfil its function with the same precision for decades.
Our instruments are famous for that!
Protect your instruments
If, contrary to expectations, your
stereomicroscope develops a fault,
please call in a specialist –
contact your local Leica agent
or Leica Microsystems Ltd.,
Heerbrugg, Switzerland.
•
from damp, vapours, acids,
alkalis and corrosive sub-
stances, and keep chemicals
away from the instruments.
•
from misuse. Never dismantle
optical systems or mechanical
parts unless instructions for
doing so are given in the user
manual.
•
from oil and grease.
Do not grease guide surfaces
or mechanical parts.
Dust and dirt will affect the quality of your results.
Therefore:
Cleaning polymer components
Some components are made of polymer, or are polymer-coated.
They are therefore pleasant and convenient to handle.
The use of unsuitable cleaning agents and techniques can
damage polymers, so always observe the following rules:
Never clean polymers this way
•
Never clean in an ultrasonic bath. The polymer
can become brittle and later break.
•
Never use corrosive cleaning agents or ones
containing acetone.
•
Never use solvents for cleaning
(except for ethanol and isopropanol).
You can clean polymers harmlessly
•
with warm soapy water, wiping down afterwards with
distilled water.
•
with ethanol (industrial alcohol) and isopropanol.
When cleaning with ethanol or isopropanol,
adhere to the appropriate safety regulations.
Put a dust cover over the instru-
ment during breaks in work.
Use dust caps to protect tube
openings, tubes without
eyepieces, and eyepieces.
Remove dust with a pneumatic
rubber bulb or with a soft brush.
Clean objectives and eyepieces
with special optic cleaning
cloths and with pure alcohol.
When accessories are not being
used, protect them against dust.
