NoZone® GP Workspace
For GenePix Scanners / Prevents Ozone Damage During Scanning

Maintains Low Ozone Levels During Scanning
Ozone levels as low as 20 ppb have been shown to degrade signals from Cy5 and other fluorescent dyes used with samples analyzed by microarrays (1). The NoZone GP Workspace [Cat. #1090-12-1 (115V); 1090-12-2 (220V)] eliminates ozone degradation of fluorescent signals that may distort microarray data during scanning of samples using GenePix scanners (MDS Analytical Technologies).The NoZone system consists of a sealed acrylic, enclosure that surrounds the scanner connected to an external ozone scrubber that continuously pumps ozone free air through the scanner space. Swing-out doors on the front of the unit allow unimpeded access to the scanner for loading and removing samples.

Compatible with All GenePix Models
The NoZone GP enclosure is designed to fit all GenePix models including the Model 4000A and B scanners and the 4200AL model with autoloading capability. The enclosure arrives fully assembled for easy installation. Just place it over the scanner, connect the ozone scrubber and turn on the power. Within a few minutes, inside ozone levels fall and remain at under 5 ppb independent of external ozone levels. Loading and unloading samples from the scanner with the door open leads to a transient increase in internal ozone levels but safe levels return in just a few minutes after closing the enclosure door.

Certified with EPA Approved Ozone Analyzer
Each NoZone GP Workspace is tested at the factory to meet reduce ozone level specifications using a highly sensitive and accurate ozone monitor. Test results are included with the system. If periodic testing of ozone levels within the enclosure is needed in conformance with GLP or CLIA guidelines, an EPA approved ozone analyzer is available for short term domestic rental (Cat. #1090-40-1).
