Applications

Technical Features

  • Precise and reliable gas incubation for O2 and CO2
  • Active and fast humidification – no evaporation
  • Uses pressurized air to create the gas flow – no vibrations
  • Optional air pressure generator available (for when pressurized air is not obtainable)

The ibidi Gas Incubation System provides both humid and CO2-rich air for stage-top incubators like the ibidi Heating System. The gas mixture is continuously flushed through the stage top incubator, ensuring a maximum humidity and an optimal pH for CO2-buffered liquids.

ibidi’s Patented Humidity Control

Cells react very sensitively to changes in medium components, such as salts and nutrients. Any evaporation from the cell culture vessels increases the substance concentration in the medium in an undefined way. To create reproducible experimental conditions, evaporation—caused by too low humidity—from cell culture vessels during live cell imaging experiments should be absolutely avoided.

The ibidi Humidity Control ensures a constant and very high relative humidity (RH) level inside the ibidi Stage Top Incubator—identical to the conditions in standard cell culture incubators. This unique and patent-protected technology actively humidifies the gas mixture in a fast and reliable way before it enters the Stage Top Incubator.

Components of the ibidi Gas Incubation System

ibidi Gas Mixer for CO2 and O2

  • Precise and reliable gas incubation
  • Active and fast humidification without evaporation (patent pending technology)
  • Suitable for various experimental conditions (e.g., pH or hypoxia)
  • Fully compatible with the ibidi Heating Systems
  • Uses pressurized air to create the gas flow – no vibrations
  • Optional air pressure generator available (for when pressurized air is not obtainable)

Humidifying Column

  • Humidifies the outgoing CO2 / O2 / air mix to minimize sample evaporation
  • Active humidity control inside the attached ibidi Heating System
