eare for Storing
Moisture and dust are the most deadly factors to microscopes. Since both
moisture and dust are found in most laboratories, microscopes should
be kept in containers immediately after use. I f this is not possible. they
should be covered with the vinyl dust cover provided.
As for objectives and eyepieces, it is best to keep them in desiccators.
Failing this, they should be kept in cases containing such desiccants as
silica gel. After.the eyepieces are removed from the microscope. the vacant
eyepiece sleeves should be covered with protective caps. By no means
should a microscope be disassembled for repairs. This should be left to
the Olympus repair service.
Microscopes must always be kept clean. F ioe dust on parts that cannot
be reached by hand should be blown or
wiped
off by means of an air
blower or a clean feather.
