Some workers (very few probably) use nitrogen gas to displace oxygen
from their chemistry containers. Others fill the containers with
marbles so that the bottle is filled with liquid, not air. There are
also schemes that use small hollow plastic balls which float on the
surface of the chemistry thus reducing the surface area of the liquid
that comes in contact with the air (a solid piece of plastic called a
"floating lid" can also be used). I usually divide my chemistry
between several smaller containers, for example one gallon of
developer into 4 @ 1 lt. bottles filling them to the tops.
