AU640 Clinical Chemistry Analyzer

by Olympus Diagnostics

Designed for the medium to high volume laboratories

Perfecting its standardized family, Olympus Diagnostic Systems Division introduces its AU640 chemistry immuno system, which is designed for the demanding environments of mid- to large-sized hospitals. This high speed automated analyzer streamlines diverse chemistry-immuno testing to provide the greatest walkaway, while processing up to 1,200 tests per hour. The new AU640 not only incorporates the proven technology of the Olympus AU600, but also includes the latest advances of its new AU400 to increase ease of use and provide more powerful performance. .


Routine sample analysis is easy with the AU640. Supplied with a Windows NT platform, the AU640 is completely user friendly. Routine testing is as simple as a click on the start icon with bar-coded samples. Operator training and system maintenance are simplified with the on-line operator's manual and context-sensitive HELP functions. A modem link to Olympus experts is included. CLIA, NCCLS, CAP compliance is supported by software documentation QC features.

The Olympus consolidated platform features a 118-test menu that also is standardized on its AU400,™ AU600,™ AU640, ™and AU2700™* analyzers. Hospitals now have increased flexibility to use the AU640 as a primary analyzer for rapid response or as a dedicated specialty unit. It can be linked to another AU400 or AU600 for even greater automation.


The AU640's test menu is completely user definable. It features over 118 methods that include general chemistries, ISEs, special chemistries, and the Syva Company Emit® TDMs, DATs, and thyroids. Barcoded liquid ready-to-use Olympus reagents provide automated on-board management of inventory and calibration and quality control.


The Olympus AU640 shares the consolidated workstation standardization of the Olympus family to provide the lowest cost per reportables in the health care market today. It uses the same methodologies across the family product lines to provide standardized results as well as common reagents, consumables and parts.

Featuring true random access testing and true STAT interrupt, the Olympus AU640 is especially suited for the hospital laboratory and its varied workload requirements. The analyzer processes a basic metabolic panel of seven tests in less than four minutes and successive panels every 45 seconds. Through its 150 sample loading capacity and continuous feed, it offers incredible walkaway and higher productivity. Manual steps are minimized through automated repeat testing, reflex testing, and automated pre-dilution for urines. As an added margin of safety, the AU640 also incorporates probe crash prevention design along with clot detection.
