OPERATION: (Con’t)
THERMOSTAT CONTROL, 315/317 SERIES FLO-THRU CO2 INCUBATORS:
A hydraulic thermostat is utilized for set point control to protect chamber
from over-temperature conditions.
OPERATING SUGGESTIONS, 315/317 SERIES FLO-THRU CO2 INCUBATORS:
• In order to obtain and maintain the desired CO2 gas pressure, periodically
check the tightness and integrity of the gasket that secures the glass door
to the chamber.
• To be sure of maintaining desired gas pressure, periodically check outflow
pressure from gas supply source.
• If maintaining humidity conditions within the chamber, check level of water
in pan and replenish as necessary.
• After power is disconnected to the unit, do not permit humidity water to
remain in the unit. Remove any pans and/or dry the interior thoroughly.
• Insofar as possible, keep the incubator door closed in order to reduce the
possibility of fungus growth starting from airborne organisms entering the
chamber.
CO2 SAMPLING/MEASUREMENT, 315/317 FLO-THRU CO2 INCUBATORS:
Insert sample probe into the sample access port making sure that a tight
seal is attained. Obtain a sample of CO2 sufficiently large to meet the
requirements of the analytical apparatus or procedure being used. Perform CO
2
analysis.
CO2 CALIBRATION, 314/316 SERIES AUTOMATIC CO2 INCUBATORS:
In like manner, the CO
2 reading can be calibrated against a known
standard such as the Fyrite method of analyzing CO2. To access the correct
command mode, press the CAL, CO2 keys sequentially.
Using a Fyrite or similar device, obtain the actual CO2 tension in the
chamber via the front panel CO2 sample port.
If there is a difference between the Fyrite reading and LED display of
CO2, press CAL and CO2 in sequence and use the Up and Down arrow keys to
adjust the displayed CO2 value to match the value obtained with the Fyrite or
device of comparable accuracy and reliability.
All internal CO
2 parameters automatically track this change: FOR
OPTIMUM OPERATION OF YOUR INCUBATOR, CHECK CO2 WITH FYRITE
WEEKLY.
