Refurbished Beckman Coulter AU400 Chemistry Analyzer

A compact Beckman AU chemistry analyzer for low- to mid-volume labs, rebuilt Down-To-Frame® to original specification and serviced by our own engineers. Finance it with $0 down.

The Beckman Coulter AU400 runs up to 400 photometric tests an hour from an 80-sample rack feeder and 76 refrigerated reagent positions. Add the ISE module and it reaches 800 tests an hour, with sodium, potassium and chloride on board. It runs the same reagents, calibrators and controls as the rest of the Beckman AU family, and every AU400 from Diamond is rebuilt to the frame before it reaches your lab.

  • Get an AU400 rebuilt to the frame, calibrated and QC-validated, instead of a used unit sold as-is.
  • Run up to 400 photometric tests an hour, or 800 on the AU400 with ISE.
  • Load 80 samples in 10-position racks, and keep adding racks while the analyzer runs.
  • Put urgent tubes in one of 22 STAT positions, and they run ahead of routine work.
  • Finance with $0 down and low introductory payments, and trade in the analyzer you're replacing.
  • Have our engineers install it, verify your assays and service it afterward. Beckman Coulter no longer services the AU400.

How the Beckman AU400 runs your chemistry menu

The AU400 is a floor-standing, random-access analyzer that reads endpoint, kinetic and fixed-time kinetic assays through permanent quartz cuvettes. Its menu goes past routine chemistry into specific proteins, therapeutic drugs, drugs of abuse, thyroid and urine chemistry.

Load barcoded 10-position racks, 80 samples at a time, and add more racks while it runs. It takes primary and secondary tubes from 11.5 to 16 mm wide and 55 to 102 mm tall.
Run urgent samples from up to 22 STAT positions, which interrupt the routine queue.
Aspirate 2 to 50 µL of sample per test in 1 µL steps, or as little as 1 µL on reruns, which helps with pediatric and short samples.
Keep 76 reagent positions refrigerated at 4 to 12 °C, with up to two reagent additions per test.
Program up to 38 photometric tests at once, plus sodium, potassium and chloride on ISE-equipped units.
Measure at 13 wavelengths from 340 to 800 nm, monochromatic or bichromatic, at 37 °C.
Mix each reaction with rotating paddles after the sample and each reagent go in.
Stop bad aspirations before they become bad results, with clot detection and crash prevention on the sample and reagent probes.
Send results to your LIS over a unidirectional or bidirectional interface.

In a 2000 evaluation of the AU400 published in Clinical Chemistry and Laboratory Medicine, within-run and between-run CVs stayed below 1.5% for the ISE tests and below 3% for most photometric analytes, and linearity exceeded the manufacturer's specifications.


Choose the AU400 version that fits your test menu

We rebuild the AU400 in four versions. All of them run the same AU reagents and test menu, so your choice comes down to whether you run electrolytes on the analyzer and which generation of hardware and software you want.

AU400. Photometric chemistry at up to 400 tests an hour, for labs that run electrolytes on another analyzer.

AU400 with ISE. Adds the ISE module for sodium, potassium and chloride, for up to 800 tests an hour.

AU400e. The later e-Class version, with upgraded hardware, updated software and a color-keyed interface.

AU400e with ISE. The e-Class version with the ISE module.

Electrolytes on a separate bench. If you want electrolytes off the chemistry analyzer, pair the base AU400 with our own SmartLyte Plus electrolyte analyzer.

Which labs buy a refurbished Beckman AU400?

The AU400 suits labs whose chemistry volume fits within 400 photometric tests an hour and that want a proven analyzer at a low capital cost.

Small hospital and community labs. Run it as your main chemistry analyzer, with STAT positions held for ED and inpatient work.

Labs that run other Beckman AU analyzers. Add it as a backup or STAT analyzer. AU analyzers share reagents, calibrators, controls and consumables, so results and reference ranges line up across your fleet.

Labs replacing a worn-out AU400. Swap in a rebuilt unit and keep your methods, QC program and operator training.

Toxicology and specialty labs. Run drugs of abuse, therapeutic drug monitoring and specific proteins alongside routine chemistry.

Labs with little capital to spend. Get a rebuilt analyzer for a fraction of what a new chemistry analyzer costs, then keep it running on one of our service plans.


Used or refurbished AU400: what a low price leaves out

Used AU400s come up through brokers, online auctions and lab closures, and many sell as-is, with no warranty and no returns. A listing that says the analyzer worked when it was decommissioned tells you it ran on its last day in someone else's lab. You still don't know the state of its probes, valves, lamp, cuvettes or reagent refrigeration, or whether it will pass calibration in yours.

Costs a used AU400 can add after you buy it

  • Decontamination, and the paperwork to prove it, before your staff can work on the analyzer.
  • Rigging and freight from the seller's site.
  • New probes, syringes, seals, tubing, valves, a photometer lamp and, on ISE units, electrodes.
  • A service engineer to repair it, calibrate it and program your assays.
  • Lost testing days if it fails validation or breaks down soon after installation.

Questions to ask before you buy a used AU400

  • What year was it manufactured, and does it have the ISE module?
  • Was it decontaminated, and can the seller document it?
  • Which wear parts were replaced, and when?
  • Does it pass calibration and multi-level QC today, and can you see the results?
  • What software version does it run?
  • When were the ISE electrodes last replaced?
  • Who installs it and programs your assays?
  • Beckman Coulter no longer services the AU400, so who will service it once it's running, and do they stock AU400 parts?
  • Does it come with a warranty, and can you return it if it fails?

Every AU400 from Diamond answers those questions before it leaves our facility. It's decontaminated, rebuilt with new wear parts, calibrated and validated with multi-level QC, then installed and verified in your lab by our engineers.

What sets the price of a refurbished AU400

  • The analyzer's year of manufacture.
  • Whether it has the ISE module, and whether it's an AU400 or an AU400e.
  • Installation, assay programming and verification in your lab.
  • Operator training.
  • The service plan you choose.
  • Freight and rigging to your site.
  • The trade-in value of the analyzer you're retiring.

Why buy your AU400 from Diamond Diagnostics?

We rebuild your AU400, prove it on QC, install it in your lab and keep it running with our own engineers.

Diamond field engineer installing a refurbished Beckman Coulter AU400 analyzer on site

Rebuilt under FDA registration and ISO 13485:2016 certification

Diamond is FDA-registered, and our US and EU operations hold ISO 9001:2015 and ISO 13485:2016 certification. ISO 13485 is the quality management standard for medical device manufacturers, so your AU400 rebuild follows documented procedures that outside auditors check.

Installed and verified in your lab

Our engineers install the AU400, program your assays and verify them before you report a patient result. Then they train your operators on site, covering daily operation, adding test parameters, scheduled maintenance and first-line troubleshooting.

Pay for your AU400 over time with $0 down

  • Finance or lease purchases up to $2 million.
  • Qualify for up to $400,000 on a credit application alone.
  • Start with $0 down and low introductory payments.
  • Get a fast credit decision and pick from a broad range of terms.
  • Roll shipping and other purchase costs into the same financing.

Trade in the analyzer you're retiring

We buy the analyzer your AU400 replaces and credit its value against your purchase. We arrange the pickup, pay the freight and handle decommissioning and decontamination, so you avoid disposal fees and the cost of storing an analyzer you no longer use.

Service, parts and consumables for as long as you run it

Every AU400 we sell is eligible for our field service plans, and so is the AU400 you already own once we qualify it.

  • Choose from four plans, from Platinum with next-day response and 24/7 phone support to Bronze with first-available scheduling.
  • Book manufacturer-recommended preventive maintenance at a fixed cost, scheduled around your lab.
  • Call or email engineers who specialize in Beckman AU analyzers.
  • Order AU consumables and service parts, including wash solution, ISE buffer, photometer lamps and pump tubing.

Beckman Coulter no longer services the AU400, so the engineers who support it after installation matter as much as the rebuild. Ours service AU400s in the field, and we supply the parts and consumables to keep yours running.


Beckman AU400 FAQ

How many tests an hour does the Beckman AU400 run?

Up to 400 photometric tests an hour. With the ISE module, it runs up to 800 an hour, counting sodium, potassium and chloride.

How much does a refurbished AU400 cost?

We price each AU400 individually, based on its year of manufacture, whether it has the ISE module and the services you add. A rebuilt AU400 costs a fraction of a new chemistry analyzer, and you can finance it with $0 down.

Should I buy a used or a refurbished AU400?

A used AU400 usually sells in whatever condition it left the last lab, often with no warranty or returns. A refurbished AU400 from Diamond is rebuilt to the frame with new wear parts, calibrated, validated with multi-level QC, then installed and verified by our engineers and eligible for our field service plans.

What's the difference between the AU400 and the AU400e?

The AU400e is the later e-Class version, with upgraded hardware, updated software and a color-keyed interface. Both run the same reagents, calibrators and test menu.

Should I buy an AU400 or an AU480?

Both run up to 800 tests an hour with ISE. The AU480 is the newer design, with master curve calibration, smaller sample volumes and room to program 63 tests at once. The AU400 costs less and runs the same AU reagents.

Do I need the ISE module?

Only if you plan to run sodium, potassium and chloride on the AU400. If you run electrolytes on another analyzer, the base AU400 covers your photometric menu.

Will an AU400 report the same results as my other Beckman AU analyzers?

AU analyzers use the same reagents, calibrators, controls and consumables, so results and reference ranges carry across the family. Our engineers verify your assays at installation.

Can the AU400 run reagents from other suppliers?

Yes. It's an open system, so you can set up applications for third-party reagents where your methods allow. Ask us about specific tests on your menu.

What does the AU400 need for power and water?

A 208 V supply, with peak draw of up to 3.5 kW, plus deionized water and a drain.

What financing is available for a refurbished AU400?

Leasing and financing cover purchases up to $2 million, with $0 down and low introductory payments. A credit application alone qualifies you for up to $400,000, and shipping can go into the financed amount.

Will you take my current analyzer as a trade-in?

Yes. We credit its value toward your AU400, arrange the pickup, pay the freight and handle decommissioning and decontamination.

Do you install the AU400 and train my staff?

Yes. Our engineers install it, program and verify your assays, and train your operators on site.

Can you service an AU400 I didn't buy from you?

Yes, once we qualify it. A qualified AU400 is eligible for the same field service plans as the ones we sell.

Does Beckman Coulter still service the AU400?

No. Our engineers service the AU400, and every unit we sell or qualify is eligible for our field service plans, from fixed-cost preventive maintenance to Platinum coverage with next-day response.
