The AU400 is the compact Olympus-era benchtop that brought automated AU chemistry to thousands of small labs, and although Beckman discontinued it years ago, it remains a fixture in physician office labs and small independents. Refurbished units are affordable, operating costs stay low, and the analyzer keeps producing results. It runs the same OSR reagent format as every AU model that followed it, so the reagents, ISE solutions, controls, and AU hardware we stock serve the AU400 alongside the current systems.
Most AU400s run in the smallest labs, and the smallest labs pay the steepest per-test reagent prices through manufacturer and big-distributor channels. We give AU400 labs the same discounted pricing the big labs get.
Every AU400 reagent we stock, by part number

Switch your AU400 reagent supplier without impacting your validation
The OSR reagents your AU400 runs came off the same production line whether the box arrives from your current distributor or from our Kentucky warehouse. Same part numbers, same package inserts, same lot documentation. Your methods, reference ranges, and QC records stay unchanged.
Most AU400s run in labs where the person ordering reagents is also the person running them, so there's no committee to convince. Send us a recent invoice and within 24 hours you'll have a line-by-line comparison at matched or better pricing. Discontinued platforms get the least attention from manufacturer sales channels, which usually makes the AU400 comparison the most lopsided one we produce.
Your chemistry reagents are always here - the free Reagents Plus program

FAQ about Beckman AU400 reagents from NextDayReagents
Why buy AU400 reagents from you instead of the manufacturer or a big distributor?
Pricing in this industry is tiered by volume, and small labs sit at the bottom of the tier. A physician office lab or independent lab buying direct, or through one of the ten large national distributors, pays list price or close to it, while hospital systems get the discounts. We give small labs big-lab pricing. Show us your current invoice and we'll match it at minimum, and most labs end up 10-15% below what they were paying.
Are these genuine Beckman Coulter OSR reagents?
Yes. Same part numbers, same package inserts, sourced through authorized distribution channels with full chain of custody documentation, lot tracking, and temperature-monitored storage from our dock to yours. Where we list a compatible third-party product, such as Phoenix Dx solutions, the brand is stated in the product name.
Do I need to revalidate my assays if I switch suppliers?
No. These are the identical OEM reagents your analyzer runs today, just purchased from us instead. Your methods, reference ranges, and QC history all stay exactly as they are.
Beckman discontinued the AU400. How long will you keep supplying it?
As long as labs run them. Discontinued AU platforms are a core part of our business, and the OSR reagent line the AU400 uses is the same one we stock for current analyzers. If your analyzer runs, we supply it.
Do you stock AU hardware like sample racks and tubing?
Yes. Sample racks, mixing bars, and pinch valve tubing are stocked alongside the reagents, so the consumable side and the hardware side of keeping an AU400 in production come from one source.
How fast will my AU400 reagents arrive?
Order by 5 PM and your reagents arrive by noon the next day. Members of our free Reagents Plus program have a full month of their supply reserved in our Kentucky warehouse at all times, so next-day delivery is a guarantee, not a best effort.
What is the Reagents Plus program?
You share 3 months of your usage history, we calculate your monthly needs, and we keep that full month of inventory reserved in dedicated storage under your lab's name. Order whenever you're running low and it arrives the next day. It's free to join, with no contracts and no minimums.
An assay I run isn't in your list. Can you get it?
Almost certainly. The table covers current stock, and we source across the full OSR menu. Send us the part number and we'll quote it at price-matched rates.
What if you can't beat my current price on a specific reagent?
We'll match it, and we'll tell you upfront if a single SKU is priced better elsewhere. Across a full reagent list, the total savings settle the question on their own.
