About the Beckman Coulter DxI 800

‍

The UniCel DxI 800 is the high-volume analyzer of Beckman's Access immunoassay family, running up to 400 tests per hour in hospital core labs and reference labs. It shares the Access reagent pack format with the DxI 600 and Access 2, so the same part numbers run across every Access-family instrument a network operates.

‍

At DxI 800 volume, substrate and wash buffer become steady bulk purchases alongside the assay packs, and the whole list price matches as one.

Switch DxI 800 reagent suppliers without slowing the line

‍

A DxI 800 running up to 400 tests an hour goes through Access packs, substrate, and wash buffer at a pace where supply and pricing both matter every week. From us, every one of those items keeps its Beckman part number and package insert. No assay revalidates, no calibration curve resets, and the QC history your lab has built stays intact.

‍

The menu is usually the wide part: thyroid, tumor markers, vitamin D, cardiac, fertility. Send the whole invoice and within 24 hours you get the line-by-line comparison across all of it, matched at minimum and typically 10-15% under, with a month of your consumption reserved in our warehouse when you join Reagents Plus.

FAQ about Beckman DxI 800 reagents from NextDayReagents

Why buy DxI 800 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 Access 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.

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.

Can you keep up with substrate and wash buffer volume on a DxI 800?

Yes. System reagents are the steadiest consumption a DxI 800 has, which makes them the easiest items to reserve accurately. Your Reagents Plus reserve is sized from your actual usage history and replenishes automatically after every order.

We run thyroid, tumor marker, and vitamin D menus. Can one comparison cover the whole list?

Yes. Send your full invoice and the line-by-line comparison covers every assay pack, calibrator, control, and system reagent on it, each matched at minimum. The wider the menu, the more the total savings add up.

How fast will my DxI 800 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 Access 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.
