Figure 3-4. Air Duct
The air duct consists of two shaped pieces of sheet metal:
1. Ceiling duct (1/ Figure 3-4 )
2. Rear wall duct (2/ Figure 3-4 )
3. Back wall of the workspace (3/ Figure 3-4 )
The air duct and HEPA filter can be installed and removed without any tools.
CO
2
Supply
To ensure the growth conditions for the cell and tissue cultures, the workspace is supplied with CO
2
.

The pH of the bicarbonate-buffered culture media largely depends on the CO
2
content of the
workspace atmosphere.

The CO
2
content of the workspace atmosphere can be controlled within a range of 0-20 %.

The supplied CO
2
must have one of the following quality characteristics:
• Purity 99.5 % min
• medical gas quality.
O
2
Supply
If the CO
2
incubator is to be operated with more than 21 % oxygen, the workspace is supplied with
oxygen (optional).

The O
2
content of the workspace atmosphere can be controlled within a range of 21 % to 90 %.
Operation with higher oxygen concentrations requires that the fire protection caution notes in Preface
in the section Safety Notes on Gases on page 7 be heeded.
