MIRI^® II-12 Multiroom Incubator

To ensure maximum performance and an environment with the least amount of stress for embryos, the Esco MIRI® II-12 Multiroom Incubator dedicates one chamber for each patient and has 24 completely separate PID temperature controllers.

The chambers are separate from one another and do not affect each other's temperatures in any way. There is no effect on the remainder of the system from any disruption in one chamber, such as a temperature reduction after opening the lid. The temperature in the culture chambers and the lids can be controlled and regulated as well. The top and the bottom of each chambers are separated with a PET layer so that the lid temperature would not affect the bottom.

For validation purposes, each compartment has a PT-1000 sensor built-in. The circuitry is separated from the unit's electronics, so it remains a truly separate validation system.

The incubator needs 100% CO₂ and 100% N2 to control the CO₂ and O₂ concentrations in the culture chambers. A dual-beam infra-red CO₂ sensor with extremely low drift rates controls the CO₂ levels. On the other hand, a chemical, medical-grade oxygen sensor controls the levels of the O₂ in the system.

Gas recovery time is less than 3 minutes after opening the lid. The MIRI® II-12 incubator is fitted with 12 gas sample ports that allow the user to validate gas concentration by sampling gas from the individual compartment.

The incubator also features a recirculated gas system where gas is continuously put into the compartment and taken out at the same rate. Gas is cleaned via a 254 nm UVC light with direct gas contact between the bulb and gas. The UVC light has filters that inhibit any 185 nm radiation that would produce dangerous ozone. The filters are located under the UVC light. The complete gas repletion in the system takes less than 5 minutes.
