DESCRIPTION

The ROXY-1™ is a stand-alone universal controller.  It features a set-point control algorithm that can regulate a single variable such as oxygen, CO2, water vapor or pressure, by using the analog output of an external analyzer or fuel cell.  The ROXY-1 can create profiled or stable environments to meet diverse experimental needs for cell and tissue culture, hypoxic and hyperoxic studies, material testing and many other applications.

Depending on how you configure it, the patent-pending ROXY-1 can function as an oxygen controller/regulator (gas phase or aquatic), a CO2 controller, a water vapor controller, or even a pressure controller. For oxygen control, it uses a standard O2 fuel cell sensor.  This is supplied with the unit if oxygen regulation is the desired application. To regulate other variables, you supply a sensor or analyzer that measures the variable you want to control.

For maximum flexibility, the ROXY-1 universal regulator can take practically any voltage input from a sensor or analyzer, from a few millivolts to over 5V. It automatically regulates its input gain to yield the best possible signal. To operate, you simply enter a setpoint and the ROXY-1 universal controller pulses the appropriate gas (which you supply) into the controlled environment until the setpoint is reached. For example, when controlling oxygen at (say) 10%, it pulses nitrogen into the chamber being regulated. Only enough to reach the user-defined setpoint is added – no more and no less – keeping tank gas use to an absolute minimum.

For research or R&D applications involving generation of controlled atmospheres, the ROXY-1 universal controller is a uniquely versatile and useful tool.

Oxygen levels tracked over approximately 70 minutes in a system regulated by a ROXY-1 gas controller. The ROXY-1 system shows tight adherence to the oxygen level set point with extremely low variability.
