Gas pressure for both inlets should be between 0.4
–
0.6 bar (5.80
–
8.70 PSI),
and it must be kept stable!
Always use a high-quality pressure regulator that can be set with the required precision
for both gases
.

Connect CO
2
gas to the CO
2
inlet with a suitable silicone tube. Ensure that the tube is
fastened with a clip so that it does not accidentally loosen itself during a sudden pressure
fluctuation. Use the supplied 0.2µ HEPA filter on the gas line just before the inlet on the
multiroom IVF incubator. Notice the flow direction.
Connect the N
2
inlet to the Nitrogen Bottle.

VOCs are hydrocarbon-based compounds that are found in fuel, solvents, adhesives and
other compounds. Examples of VOCs include isopropanol, benzene, hexane, formalde-
hyde, vinyl chloride.
VOCs can also occur in medical gases, such as CO
2
and N
2
. It is essential to use in-line VOC
filters to prevent these fumes from entering your multiroom IVF incubators for your med-
ical gasses.
Unexpected sources of VOCs are commonly found in IVF labs. These can include cleaning
agents, perfumes, cabinetry, grease on the wheels of equipment and sources in HVAC
equipment.
