TRI GAS MIXER

The Tri-Gas Mixer delivers gas mixture of the desired CO2 and O2 concentration with output pressure in the range of 0-2 bar (0-30 psi). Delivery pressure is easily regulated by adjusting the knob of the embedded pressure gauge.

The device is equipped with a mixing tank to ensure the highest composition stability even when the required output flow is variable.

Models available with maximum output flow rate of 1.5 L/min and 15 L/min. The actual flow rate delivered automatically adjusts to match the requirements of the equipment connected.

The Tri-Gas Mixer is compatible with any mini incubator available on the market.

CO2-O2 Sensor Calibration

The CO2-O2 sensor module stores the calibration in local memory.

The CO2-O2 sensor module can be conveniently calibrated on-site with intuitive routines or can be easily extracted from the Tri-Gas Mixer, replaced with a spare CO2-O2 sensor module and sent out for calibration.

In both cases, there is no need to disconnect or turn off the Tri-gas Mixer nor to discontinue the gas supply to the incubators.

Gas Input Requirements

The Tri-Gas Mixer must be connected to pressurized sources of CO2 - N2 - Air. Minimum input pressure is related to the desired delivery pressure according to P input= P output+ 1.3 bar (20 psi).

Okolab air compressors are available to provide pressurized background air.

 

Available Models

The Tri-Gas Mixer is available in two models, with maximum output flow rate capacity of 1.5L/min and 15L/min. Besides internal components, the two models differ by the size of the mixing tank (specs in the back of this brochure).

Safety Features

The Tri-Gas Mixer features advanced safety routines to ensure that the incubators always receive the proper gas.

To enable the safety routines the Tri-Gas Mixer must also be connected to a pre-mixed back-up cylinder containing gas of the desidered concentration.

The mixer will automatically switch to the backup pre-mixed cylinder if any of the following conditions occurs: 

  • pressure in the mixing tank becomes too low (for instance due to gas requirement exceeding maximum mixer capacity)
  • pressure of any of the input gasses becomes too low
  • target gas concentration cannot be achieved.
