Gas Incubation System

7

Maintenance

7.1

CO

2

Sensor Auto-Recalibration

At least once per week the Gas Mixer must be turned off for 5 minutes. This is necessary for the
flow sensor’s onboard automatic calibration routine, which needs an atmospheric CO

2

measurement

to compensate sensor drift. When again switching on the system, the CO

2

sensor calibration is run

automatically (see Section

5.3

).

7.2

Disinfection and Cleaning

7.2.1

Wiping the Outer Surface

To clean the Gas Mixer and Humidifying Column from the outside, switch the Gas Mixer off and dis-
connect all cables and tubing. Leave the instrument to cool down for approximately 5 minutes. Use
only dry cloth or a cloth dampened with water (ultrapure) or common lab disinfection solutions that
are based on quaternary ammonium compounds (e.g., Barrycidal 36 or Pharmacidal). Fingerprints
can be removed using ethanol or isopropanol (70%) or lens/eyeglass cleaning wipes.

Caution!

70% ethanol or isopropanol can be used to wipe the Humidifying Column from the outside. Do
not use any other organic solvents. Do not expose to ethanol or isopropanol for an extended
period of time. It can lead to damage of the Humidifying Column.

7.2.2

Cleaning the Column’s Inner Face

Microbial contamination in the Humidifying Column is usually not a problem since distilled water
and light-starved environments (microscopy rooms) do not support microbe growth. If, however,
contamination has occurred, disinfect the Humidifying Column by running the system with 3% hy-
drogen peroxide for 1 hour. Subsequently wash with water. The use of anti-microbial agents is not
recommended since they can be transported as aerosol and end up in the specimen.

7.3

Influence of Surrounding Temperature and Airflow

The surrounding, ambient temperature affects the temperature inside the microscopy chambers. De-
vices, such as computers and camera controllers, can significantly heat up small rooms. In this case,
we recommend equilibrating the room temperature to the typical experimental conditions at least
2–3 hours before starting the experiment.

Airflow can enhance the effect of temperature and humidity changes in the vicinity of the incubation
chamber. In cases where airflow (e.g., air conditioning) cannot be stopped, we recommend protecting
the microscope as much as possible from it.
