The miniZ is the latest addition to the RBD Instruments line of water vapor desorption / oxidative hydrocarbon removal systems. This water vapor desorption system comprises a high power UVC emitter that fits inside a standard 1.5" I.D. vacuum chamber tube and a compact power supply which mounts directly to the 2.75" CF flange.
185nm UVC radiation provides the correct wavelength of energy to desorb water vapor molecules from the chamber walls and results in faster chamber pump down times and lower ultimate vacuum.
Produces 350 uW/cm2 @ 6cm from end of emitter (2.75" flange)
