Contamination
The chamber is contaminated.  Your unit is not cleaned and
decontaminated often enough.


 If your unit becomes
contaminated even after you
follow an appropriate
maintenance regimen, the
source of the contamination is
probably not the incubator.

page 14 for recommendations
and instructions on
decontaminating your unit.

contamination, such as water
baths, hoods, autoclaves,
reagents, disposables,

even after you follow an
appropriate maintenance
regimen, the source of the
contamination is probably not
the incubator.
