5 Reasons Labs Rely on the Beckman Coulter AU640e Chemistry Analyzer
The AU chemistry line has one of the most trusted reputations in clinical laboratory diagnostics, and it isn't hard to see why. Originally developed by Olympus before the platform transitioned to Beckman Coulter, the AU series has spent decades earning a reputation as one of the most widely deployed open-reagent chemistry systems in the US laboratory marketplace.
The Beckman Coulter AU640e sits squarely in the sweet spot of that lineup: enough throughput for serious daily chemistry volume, without the floor space and infrastructure demands of the largest AU-series systems.
Here are 5 reasons laboratory directors continue to choose the AU640e for their core chemistry needs.
1. Dependable 800 Tests-Per-Hour Throughput
The AU640e delivers a maximum throughput of 800 tests per hour, positioning it as a strong mid-to-high volume workhorse for hospital core labs and reference facilities. That capacity keeps turnaround time (TAT) consistent even as daily order volume fluctuates throughout the day.
2. A Genuinely Broad Assay Menu
With 89 tested assays spanning cardiac markers, drugs of abuse, lipids, liver function, metabolic panels, renal function, and therapeutic drug monitoring, the AU640e lets laboratories consolidate the vast majority of their routine chemistry menu onto a single platform, reducing the need to split samples across multiple analyzers.
3. High Onboard Reagent Capacity
The system supports 48 onboard reagent positions with on-board refrigeration, minimizing how often technologists need to interrupt a run to restock reagents. Combined with a 150-sample load capacity, this lets labs run longer batches with fewer manual interventions.
4. True STAT Prioritization
The AU640e supports direct STAT sample loading, allowing urgent samples to be processed without disrupting the routine testing queue. For hospital labs balancing outpatient chemistry volume against emergency and inpatient demand, that flexibility matters as much as raw throughput.
5. Proven Reliability at a Fraction of New-System Cost
The AU series' open reagent system gives laboratories flexibility in reagent sourcing, helping control cost-per-test without narrowing the assay menu. And because the AU640e has such a long, well-documented service history, a certified refurbished unit delivers dependable, familiar performance at a significantly lower acquisition cost than newer AU-series or comparable competitor platforms.
