• Full range real-time control of both Oxygen and Carbon Dioxide gas in dual gas streams
• Dual streams for simultaneous control of gas phase and liquid phase in live cell microscopy
• Eliminates inflexibility of premixed gas - Easily switch from one gas concentration to another
• Eliminates the high cost of premixed gas
• Eliminates inaccuracies due to gas stratification in premixed gas tanks
• Vertical footprint saves bench space

The OxyStreamer® provides two identical streams of any mix of oxygen and carbon dioxide gas without the use of premixed gas cylinders. The two output streams can be used to simultaneously condition the atmosphere in a microscope stage mount cell culture incubators/chambers and the dissolved O2 and CO2 levels in media or perfusate.

By independently monitoring and controlling O2 and CO2 concentrations of the streams, the OxyStreamer can monitor and proportionally mix (blend) oxygen, carbon dioxide and nitrogen gases into any O2 and CO2 concentration in real time.

The OxyStreamer® is easy to use. After calibrating the O2 and CO2 sensors, the desired concentrations for O2 and CO2 are simply entered into their respective controllers using the digital display and up/down control buttons. The closed-loop dynamic gas control system will then automatically monitor and adjust the output stream of gas to the pre-programmed gas ratios in the controllers. This technique will maintain the output mixed gas concentration to within 0.2% of the selected set-point levels.

The flow rate for each stream is independently controlled for gas efficiency and to provide a method for setting a reproducible rate at which the gas is delivered to the cell culture chamber and/or diffused into the cell culture media or perfusate.

The inlet ports for the gases on the back of the unit are ¼" hose barb fittings and will take standard ¼" ID tubing. Output stream ports are quick disconnect fittings that use 1/16" or 1/8" ID tubing.

Options include a Windows® based software package that provides trend plotting, data logging, and remote operation via RS-232 connection to your PC. Multiple OxyStreamer® can be daisy chained via optional RS-485 interface.
