pH Electrodes offer drift-free reference system.

Press Release Summary:



Orion ROSS Ultra screw-cap electrodes are available in standard glass-bulb, flat-surface, semi-micro, and epoxy-bodied styles to best determine pH of variety of sample types. Screw-capped electrodes accommodate applications such as titrations. ROSS Ultra half-cell reference electrode is available for applications where separate sensor and reference electrodes are preferred.



Original Press Release:



Thermo Electron's Orion ROSS Ultra® Screw Cap pH Electrodes Extended Line is Now Available



Chicago (March 8, 2004) - Thermo Electron Corporation (NYSE:TMO), a leader in the developnent and manufacturing of chemical measurement product lines, introduces the Orion ROSS Ultra screw cap electrodes, extending the premium Orion ROSS Ultra combination pH and reference electrode line.

Researchers, QA/QC and general lab technicians from around the world are finding the virtually drift-free ROSS Ultra electrode is the best electrode they have ever used. The fast response time and equilibration provide faster sample throughput. The drift-free reference assures fewer calibrations, again translating to faster throughput and cost savings per test. The ROSS Ultra pH line has grown again to accommodate applications such as titrations, where a screw-capped electrode is preferred. ROSS Ultra electrodes use a unique reference system developed by Thermo that offers longer life, greater stability, and fast results, regardless of sample composition or temperature. ROSS Ultra pH electrodes are available in a rugged and standard glass bulb, flat surface, semi-micro and epoxy bodied styles to best determine the pH of a variety of sample types, now with a screw cap option for time saving in the laboratory.

A ROSS Ultra half-cell reference electrode is also available for applications where separate sensor and reference electrodes are preferred. ROSS Ultra combination pH electrodes are also available as Orion meter and electrode packages. Due to the outstanding innovations and performance of these electrodes, the ROSS Ultra line carries twice the warranty due to greater stability than its predecessor electrodes.

The ROSS Ultra pH line includes the following features:
o Unmatched drift-free reference system
o Unparalleled pH response to temperature changes
o Handles even the most difficult samples
o Extended 24 month warranty

This and many other Thermo Electron products will be exhibited at the 2004 Pittsburgh Conference (Pittcon), which is being held from March 7-12 in Chicago, Illinois. Please visit us at booth #1475.
