Has the specimen
dried up?
Heated Stage warmth can dry up an
insuciently protected specimen. A generous
layer of mineral oil over the specimen will
protect it from drying out.
Are the media you
are using within
their shelf life?
Some media and PVP deteriorate if stored
past their shelf life or if they have not been
kept refrigerated during storage or transit.
