S
UPPLY TO THE
I
NCUBATOR
Note: Always use medical grade CO
2
. Use of non-medical grade CO
2
risks introducing
contaminants into the chamber, may damage the incubator, and will void the incubator’s
warranty.
Always install the in-line filter provided with the unit tubing kit between the gas source and the
incubator. The filter is directional. Make sure that it is installed correctly with the side stamped “IN”
facing toward the supply source.
SCO Incubators use only small quantities of CO
2
. Precise regulation of gas input is vital for the
incubator’s performance. Always use a two-stage CO
2
pressure regulator. Some single-stage
regulators have 2 gauges. Make certain your regulator is a two-stage regulator.
Set the CO
2
regulator within the operational range of 15 – 25 Pounds per Square Inch (PSI). Do
not exceed 25 PSI.
PSI Megapascals Kilopascals Bar
15 - 25 PSI 0.103 – 0.172 Mpa 103.42 – 172.37 Kpa 1.03 – 1.72 bar
Please see the Pressure Units Conversion table on page 38 in the Unit Specifications section for
the formulas for converting PSI into other units of pressure measurement.
