Gas Incubation System 1.10 Repairing the Gas Incubation System For inquiries concerning repair service, contact the ibidi service personnel and provide the model name and serial number of your system. ibidi GmbH Service Hotline: service@ibidi.com CAUTION Do not try to repair the Gas Incubation System by yourself. Disassembly of the Gas Incubation System is not allowed.
Incubation System mixes the required gas ratios in the output and actively humidifies this mixed gas output before the gas enters the incubation chamber. Two versions of the Gas Incubation System are available: the ibidi Gas Incubation System for CO and the ibidi Gas Incubation System for CO and O .

Gas Incubation System Figure 3 – Back view of the Gas Mixer. 4.3 Humidifying Column The Humidifying Column provides a water reservoir to humidify the mixed gas. Part of the mixed gas output is guided through the column. The water inside the column is warmed up for higher humidity uptake.
Gas Incubation System are combined in the tubing leading to the stage top incubator. By varying the flow rates of the two gas streams, the humidity can be controlled. The gas tubing carrying humidified gas is heated up to avoid condensation. For this purpose, a heating wire is inserted in the tubing.

Gas Incubation System To ensure accurate humidity measurements , the humidity sensor must be mounted securely in the plastic through-hole in the side of the Heated Lid. To do this, please follow the steps below: 1. Check that the spacer nut is fixed on the humidity sensor’s threaded connector. 2.
Gas Incubation System 5 Operation The components must be assembled in the following order: 1. Connect all tubing and cables. 2. Apply 1 bar (14.5 psi) to the connected gas tubing. 3. Switch on the Gas Mixer. Caution! Not maintaining this order may lead to device malfunction or damage! The procedure is explained in detail in the following sections.
Gas Incubation System 5.1.1 Connection to the Gas Supply The gases from the bottle or laboratory gas line need to be connected to the Gas Mixer with the OD 6 mm polyurethane tubing of the respective color. This tubing is delivered with the system. Table 5 –...
Gas Incubation System Position „OFF“ Figure 11 – Close the N port of the Gas Mixer with the dead end tubing if not needed (CO version only). Warning! Only disconnect the tubing when there is no pressure on the gas line. First, switch off the pressure from the gas line.
Gas Incubation System 5. To connect the mixed and humidified gas output to the Heated Chamber, screw the Luer Lock connector into the metal adapter that is fixed in the wall of the Heated Lid. Figure 12 – Connection of the Heated Tubing Package to the Gas Incubation System. Caution! Do not disconnect the Heated Tubing while the Gas Mixer is running.
Gas Incubation System Figure 13 – Connection of the humidity sensor cable to the humidity sensor. 5.1.4 Connection of Power Supply (and USB optionally) To finish the setup, the power supply must be connected. Optionally, the USB cable can be used to connect the Gas Mixer to an external computer.
Gas Incubation System Open the blue stopper on top of the column and use a wash bottle to fill it with ultra-pure water. The water level must be in between the minimum and maximum mark (Figure 14). The re-filling of the Humidifying column can be done during operation, without stopping the Gas Mixer.
Gas Incubation System For most applications, we recommend using the values given in Table 7. The full specification range is indicated in the specifications (Section 1.4). Caution! Be aware that when the system is switched on, some parts of the tubing are actively heated: The Humidifying Column base (max.

Gas Incubation System 6 IncuControl Software The Gas Mixer has a USB interface for computer control and data logging. For this purpose, ibidi provides the IncuControl software that comes with the controller or can be downloaded from the ibidi website.
Gas Incubation System 7 Maintenance 7.1 CO Sensor Auto-Recalibration At least once per week the Gas Mixer must be turned off for 5 minutes. This is necessary for the flow sensor’s onboard automatic calibration routine, which needs an atmospheric CO measurement to compensate sensor drift.
Depending on the incubating conditions, small volumes might evaporate quickly, especially during long-term experiments. If you have an actively controlled humidifying device (e.g. ibidi Gas Incuba- tion System), increase the set value for relative humidity. Additionally, we suggest using silicone oil (e.g.
Check the temperature of the chamber (Heated Lid and Heated Plate). Make sure the humidity sensor is not in contact with the Heated Lid. In case of condensation, decrease the humidity and air-dry the incubator if necessary. Please contact ibidi at techsupport@ibidi.com for further troubleshooting help.
