New Brunswick Scientific User’s Guide
For IVF and other sensitive work, we do not recommend the use of any biocide in the
humidity tray. To reduce the possibility of contamination, every 10 to 14 days, empty
the tray, clean it with a solution of 70% isopropyl alcohol and 30% distilled water, and
then refill it with 0.5 liters of warm distilled water.
To remove the humidity tray, turn it 45º to clear the shelf rack supports (see Figure 3a).
CAUTION!
Never leave water in the humidity tray while the incubator is switched
off, or when a high temperature disinfection cycle is initiated, to avoid
possible damage to the CO
2
sensor.
The humidity level within the chamber can be manually adjusted from ~95% to ~97%.
The controller to adjust the humidity level is found on the lower, front right side of the
instrument. The black adjustment knob can be rotated clockwise for standard (~95%)
humidity levels, and counter-clockwise to increase the humidity level.
NOTE:
The humidity tray should always be left in place, even if the incubator is
not being humidified.
3.4 Setting Temperature & CO
2
At this time, program the desired Temperature and CO
2
setpoints. Temperature and
CO
2
may be set within the following ranges:
Table 4: Temperature & CO
2
Setpoint Ranges
Parameter Available Setpoint Range
Temperature 10ºC to 50ºC
(must be at least 4ºC above ambient)
CO
2
0.2% to 20%
To set the Temperature:
1. Press the Programming (¤) key.
2. Press the Up ( S ) or Down ( T ) key until the desired value appears in the
lefthand display.
3. Press the
enter key to save the setpoint.
4. Now you can set the CO
2
level.
