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.

ACTIVE HUMIDITY CONTROLLERS

Active Humidity Controllers control the Relative Humidity inside the chamber in the range 50-95% with a resolution of 1%.

Features

  • Connects to any Bold Line Gas controller
  • Controlled via OKO-TOUCH
  • Humidity sensor resolution 1%
  • A heated tube connects the Active Humidity Controller to the Chamber
  • Stand alone version (HM-ACTIVE-STANDALONE) is available to run the humidifier independently of the gas controller.
  • TTL signal compatibility, upon request

The dry gas is humidified by flowing over warm water. The Humidity sensor regulates water temperature in order to achieve the desired relative humidity in the chamber.

To prevent water condensation, the tube connecting the humidity controller to the chamber is heated.
