What the Beckman DxC 500 AU handles on your bench
The DxC 500 AU is a random-access analyzer that measures by spectrophotometry and indirect ISE, running colorimetric, turbidimetric and latex agglutination assays on serum, plasma, urine, cerebrospinal fluid and whole blood.

Which labs buy a refurbished Beckman DxC 500 AU?
The DxC 500 AU chemistry analyzer is for small and mid-size labs, and for the satellite labs that feed a health system's central lab.
local_hospitalCommunity hospital labs. Run routine chemistry, electrolytes and HbA1c on one analyzer, with STAT samples taking priority from the refrigerated carousel.
sync_altSatellite and outreach labs in a health system. Match the hub's AU reagents, assay protocols and reference ranges, so results line up across sites.
upgradeLabs replacing an older compact AU analyzer. Keep your AU reagents and methods, and gain continuous loading, longer calibration intervals and a current Windows 10 workstation.
scienceLabs bringing HbA1c in-house. Load whole blood tubes with the rest of the work, with no manual prep.
paymentsLabs that want a current-generation analyzer on a tight budget. Get the newest Beckman analyzer in this class for up to 70% less than new.
DxC 500 AU with or without ISE
The DxC 500 AU is available in two configurations. Everything else about the analyzer is the same, so the choice comes down to where you run electrolytes.
DxC 500 AU. Up to 400 photometric tests an hour, for labs that run sodium, potassium and chloride on a blood gas or standalone electrolyte analyzer.
DxC 500 AU with ISE. Adds long-life ISEs for sodium, potassium and chloride and reaches up to 800 tests an hour, or up to 600 in ISE-only mode.

DxC 500 AU or AU480?
The AU480 covers the same volume range at the same throughput, up to 800 tests an hour with ISE, on the same AU reagents. The DxC 500 AU holds 168 samples against the AU480's 80 and loads reagents while it runs. It also offers whole-blood HbA1c without prep and calibration curves that hold up to 90 days on many assays. A refurbished AU480 costs less, and a refurbished DxC 500 AU gives you the current platform.
Tell us your daily volume and how you run electrolytes now, and we'll recommend a configuration.

Q: How much does a refurbished DxC 500 AU cost?A: Up to 70% less than a new one. We price each unit on its configuration and the services you add, and financing starts at $0 down.
Q: How many samples does the DxC 500 AU hold?A: 168 tubes in racks of seven, loaded continuously, plus 22 positions in the refrigerated STAT carousel.
Q: Can the DxC 500 AU run HbA1c?A: Yes. Beckman's HbA1c assay runs from whole blood loaded with the rest of your samples, with no manual prep.
Q: How many assays can the DxC 500 AU keep on board?A: Up to 60 analytes in its 76-position reagent carousel, plus sodium, potassium and chloride on ISE units. Beckman offers more than 135 preprogrammed photometric applications for it.
Q: What's the difference between the DxC 500 AU and the AU480?A: Both run up to 800 tests an hour with ISE on the same AU reagents. The DxC 500 AU holds 168 samples instead of 80, loads reagents while it runs, and offers whole-blood HbA1c and calibration curves stable up to 90 days on many assays. A refurbished AU480 costs less.
Q: Will the DxC 500 AU match results from our other Beckman AU analyzers?A: Beckman built it on the same standardized reagents, assay protocols and reference ranges as its other AU analyzers, so results line up across sites. Our engineers verify your assays at installation.
Q: What utilities does the DxC 500 AU need?A: 200 to 240 V power at 60 Hz, a continuous supply of CAP Type II deionized water at up to 20 L an hour, and a drain within 10 m (33 ft) of the analyzer.
Q: What financing is available?A: Leasing and financing up to $2 million, with $0 down and low introductory payments. An application alone qualifies you for up to $400,000, and shipping can go into the financed amount.
Q: Will you take my current analyzer as a trade-in?A: Yes. We credit its value toward your DxC 500 AU and handle pickup, freight, decommissioning and decontamination.
Q: Do you install the DxC 500 AU and train our staff?A: Yes. Our engineers install it, program and verify your assays, and train your operators on site.
Q: Can you service a DxC 500 AU we bought elsewhere?A: Yes, once we qualify it. A qualified DxC 500 AU is eligible for the same field service plans as the units we sell.
