What the Beckman AU680 brings to a mid- to high-volume lab
The AU680 is a random-access analyzer that measures by spectrophotometry and indirect ISE. It runs colorimetric, turbidimetric, latex agglutination and homogeneous enzyme immunoassay methods on serum, plasma, urine, whole blood and other fluids.
autorenew
Keep samples moving through peak hours
Load 150 samples in barcoded 10-position racks, and add racks while it runs. Tubes from 11.5 to 16.5 mm wide and 55 to 102 mm tall fit.
Put urgent tubes in a cooled 22-position STAT compartment and start them with one button. The same compartment holds calibrators and controls for automatic calibration and QC.
Send priority reruns and reflex tests ahead of routine work for critical patients.
water_drop
Run a broader AU680 test menu
Keep 60 first-reagent and 48 second-reagent positions refrigerated at 4 to 12 °C, with handling for assays that need a third reagent.
Run HbA1c from whole blood, with no manual pretreatment.
Aspirate 1 to 25 µL of sample per test in 0.1 µL steps, and 15 to 250 µL of each reagent.
Load master calibration from the 2-D barcode on each reagent bottle.

Replace common AU680 parts in under a minute
Change sample and reagent probes, mixers and syringes in three steps or fewer, in under 60 seconds, with no tools.
Follow help videos built into the software for maintenance and parts replacement.
lan
Precise AU680 readings and LIS connectivity
Read reactions in quartz cuvettes at 37 °C, at 13 wavelengths from 340 to 800 nm, for up to 8 minutes and 40 seconds.
Catch clots and prevent probe crashes on the sample and reagent dispensers.
Store results for 100,000 samples, and connect to your LIS one-way or bidirectionally.
Run the AU680 standalone or connect it to your automation
The Beckman AU680 works on its own or as part of an automated line.
crop_squareStandalone. Load samples through the 150-sample rack loader and the cooled STAT compartment.
conveyor_beltOn an automation track. Sample directly from a Beckman automation track, so tubes go from the line to the analyzer without being reracked.
biotechFrom a pre-analytical workstation. Move samples straight into the AU680 on a standardized rack tray.
join_innerAlongside an immunoassay analyzer. Link the AU680 with a Beckman immunoassay analyzer into an entry-level automated system, with one point of sample entry and an integrated decapper.
lanMonitored remotely. Use Beckman's middleware to watch instruments and automation consoles from a single workstation.

AU680 or Beckman's newer DxC 700 AU?
The DxC 700 AU is Beckman's next generation for the same mid- to high-volume labs. Both run at the same throughput. The DxC 700 AU adds reagent loading while the analyzer is measuring. The AU680 gives you the same throughput and menu, with fewer convenience features, for less.
Tell us your daily volume and whether electrolytes run on your chemistry analyzer, and we'll recommend the configuration.
Plan your AU680 installation: floor space, power and water
The AU680 measures 195 cm (76.8 in) wide, 100 cm (39.4 in) deep and 128 cm (50.4 in) tall, about 21 sq ft of floor before service clearance. It weighs about 460 kg (1,014 lb), so check your floor loading and delivery route ahead of time.

Beckman AU680 price: refurbished, new or used
A refurbished AU680 from Diamond costs up to 70% less than a new one, and you own it outright.
As labs upgrade to newer analyzers, used AU680s reach the market through brokers, auctions and lab closures. The asking price on a used unit covers the analyzer as it left the last lab. Decontamination, worn parts, an engineer's visit and validation in your lab come after, and they come out of your budget.
Before you buy a used AU680, confirm
The year of manufacture and serial number.
Whether it has the ISE module, and the age of its electrodes.
Documented decontamination.
Which probes, syringes, mixers, seals and tubing were replaced, and when.
Current calibration and multi-level QC results.
The software version installed.
That Beckman's field safety notices for its serial number were completed.
Who installs it, programs your assays and verifies them.
Who services it afterward, and whether it comes with a warranty or a return policy.
Every refurbished AU680 from Diamond is decontaminated, rebuilt with new wear parts, calibrated and validated with multi-level QC before it leaves our facility, then installed and verified in your lab by our engineers.

Why labs choose a refurbished AU680 over a new analyzer
paymentsCapital you keep. You save up to 70% compared with new and can put the difference toward staff, reagents or a second analyzer.
keyOwnership. The analyzer is yours, outside any reagent contract, and you decide who services it.
scienceThe same AU results. A refurbished AU680 runs the same Beckman AU reagents and applications as a new one.
recyclingLess waste. Rebuilding a working analyzer keeps it out of landfill and uses less energy and material than manufacturing a new one.
Why labs buy refurbished AU680 analyzers from Diamond Diagnostics
We rebuild the AU680 from its frame, validate it on QC, install it in your lab and keep it running with our own engineers.
build
Rebuilt Down-To-Frame®, assembly by assembly
Our technicians decontaminate the AU680 and take it down to the frame. They restore or replace every mechanical, pneumatic and electronic assembly, from the rack loader and STAT compartment to both reagent compartments, the cuvette wheel and the photometer, and fit new probes, syringes, seals, tubing and reagent lines. The analyzer is calibrated with certified calibrators and validated with multi-level QC, and we run the assays on your menu when you ask.

Beckman AU680 questions, answered
Q: How many tests an hour can the Beckman AU680 run?A: Up to 800 photometric tests an hour, or up to 1,200 with the ISE module, counting sodium, potassium and chloride.
Q: What does a refurbished AU680 cost?A: Up to 70% less than a new one. We price each unit individually, based on its year of manufacture, whether it has the ISE module and the services you add.
Q: Why buy a refurbished AU680 instead of a used one?A: A used AU680 comes as it left its last lab, often with no warranty or returns. A refurbished AU680 from Diamond is rebuilt to the frame with new wear parts, calibrated and validated with multi-level QC, then installed and verified by our engineers and eligible for our field service plans.
Q: How many tests does the AU680 hold on board?A: 63: 60 photometric tests plus sodium, potassium and chloride on ISE units, from 60 first-reagent and 48 second-reagent positions.
Q: Can the AU680 run HbA1c?A: Yes. It samples whole blood for HbA1c, with no manual pretreatment.
Q: What's the difference between the AU680 and the AU640?A: The AU680 replaced the AU640 with higher throughput. It holds 60 photometric tests on board instead of 48, adds three-reagent assays, whole-blood HbA1c and barcode calibration, and takes smaller sample volumes.
Q: Should I buy an AU680 or a DxC 700 AU?A: Both run up to 800 photometric tests an hour, or 1,200 with ISE, on the same AU reagents. The DxC 700 AU adds reagent loading while it measures. The AU680 costs less.
Q: Can the AU680 connect to lab automation?A: Yes. It can sample directly from a Beckman automation track, take racks from a pre-analytical workstation, or link with a Beckman immunoassay analyzer.
Q: Can the AU680 run reagents from other suppliers?A: Yes, on tests where your methods allow. It's an open system, so you can set up user-defined applications. Ask us which tests on your menu qualify.
Q: What power and water does the AU680 need?A: 200 to 240 V power at 50 or 60 Hz, up to 3.8 kVA, plus deionized water and a drain.
Q: What financing is available?A: Leasing and financing up to $2 million, with $0 down and low introductory payments. A credit application alone covers up to $400,000, and you can add shipping to the financed amount.
Q: Will you take my current analyzer in trade?A: Yes. We credit its value toward your AU680 and handle pickup, freight, decommissioning and decontamination.
Q: Do you install the AU680 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 an AU680 I didn't buy from you?A: Yes, once we qualify it. Every AU680 we qualify is eligible for the same field service plans as the ones we sell.
