Part of the medium can evaporate, in particular in case of small vol-
umes of work (e.g. when using microtitre and deep well plates) and
long cultivation processes. To reduce evaporation of the medium, the
device can also be fitted with Hygienic Humidity Control. This regu-
lates the humidity in the incubation chamber to a defined setpoint
and thus ensures a consistent culture volume.
Humidity control allows both humidification and dehumidification of
the air in the incubation chamber.
Humidification:
■
A controlled water pump feeds water into an evaporator chamber
via a feed hose. The water is heated, evaporates and is then
fed directly into the incubation chamber. At the same time, a dia-
phragm pump enriches the steam in the evaporation chamber with
ambient air. This has the effect that the air remains above the dew
point when entering the incubation chamber. This prevents water
from condensing in the incubation chamber.
Dehumidification:
■
To dehumidify the air in the incubation chamber, ambient air is
introduced into the incubation chamber. This reduces the relative
humidity in the incubation chamber, that is, the air is dried.
