(IVF) / assisted reproduction technology (ART) treatments. 4 About the product Esco Medical MIRI II-12 multiroom IVF incubator is a CO incubator. ® Direct warming of the dishes in the chambers gives superior temperature conditions in comparison to conventional multiroom IVF incubators.
The multiroom IVF incubator has been primarily developed and designed for incubation of gametes and embryos with an overlay of either Paraffin or mineral oil. The multiroom IVF incubator has a built-in PC which operates the Esco Medical Data logger software for long-term data logging and data storage.
A visual inspection should be done if there is any damage. If no damage is found, the MIRI ® II-12 multiroom IVF incubator can be prepared for transport. These labels should be glued on the box: • Label with the marked packing date •...

CO control in the compartment is available in the range from 3.0% to 10.0%. inlet should be connected to a 100% concentration N if low oxygen conditions are required.
12 HEPA/VOC filter VOCs are hydrocarbon-based compounds that are found in fuel, solvents, adhesives and other compounds. Examples of VOCs include isopropanol, benzene, hexane, formaldehyde, vinyl chloride. VOCs can also occur in medical gases, such as CO and N . It is essential to use in-line VOC filters to prevent these fumes from entering your multiroom IVF incubators for your medical gasses.

Figure 15.1 Temperature zones in the MIRI II-12 multiroom IVF incubator ® Each area can be calibrated separately, using the item corresponding to the respective area in the menu. These items are placed in the menu and they are named the following: T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18, T19, T20, T21, T22, T23 and T24.
Be careful when changing the calibration settings – make sure that only the altered value corresponds to where the measurement is done. Give the system some time to adjust. There is no crossover heating between the 12 compartments: This is a unique feature of the MIRI II-12 incubator.
Figure 16.2 O pressure on the main display The N pressure value is shown in bar. The external pressure must be between 0.4 – 0.6 bar (5.80 – 8.70 PSI) at all times. It cannot be adjusted on the incubator; this must be done on the external gas regulator.

According to the temperature level set in the calibration dialogue window on the screen, the system does temperature correction (ATC) according to the calibration dialogue window's temperature level. An external ATC probe cannot be used with the system. Figure 18.1 BNC pH line connection The temperature level must be set to a correct level in the calibration dialogue window on the screen (corresponding to a measurement done with an external device).

Figure 18.3 4-well dish with 3 buffers and media For calibration, at least two buffers are needed. We recommended using 3 buffers. One of the buffers should have a 7 pH. Any pH buffer can be used as the user's buffer levels can be set in the calibration dialogue window.
After the calibration is performed and saved, quick pH measurement can be done in the culture media. Ensure the probe tip is well covered with media and that the opening through the test lid is sealed sufficiently to maintain gas levels (use tape or rubber seal). The set-up can measure the pH continually.
