Horiba ABX Pentra Magnesium RTU Reagent – ~200 Tests – Pentra 400 / C400 (P/N 1220001646)

What is it:

The Horiba ABX Pentra Magnesium RTU (P/N 1220001646, REF A11A01646) is a genuine HORIBA ready-to-use (RTU) reagent for measuring magnesium on the ABX Pentra 400 / Pentra C400 clinical chemistry analyzer. It uses a photometric xylidyl blue method and is supplied as 2 × 25 mL, good for approximately 200 tests. For professional in vitro diagnostic use.

Part numbers:

• Catalog P/N: 1220001646
• Box REF: A11A01646

What it's used for:

Magnesium RTU measures magnesium in serum and plasma — used to evaluate metabolic and electrolyte disorders, monitor patients on long-term IV therapy, and investigate conditions associated with abnormal magnesium levels. The assay uses a photometric xylidyl blue method: magnesium binds the xylidyl blue dye to form a colored complex the analyzer measures, with the signal proportional to the magnesium concentration. As a routine electrolyte/metabolic test, this is a regularly reordered reagent, used together with the appropriate calibrator and controls.

What's included:

• ABX Pentra Magnesium RTU, 2 × 25 mL
• Approximately 200 tests
• Manufactured by HORIBA ABX SAS

Compatible analyzer:

• ABX Pentra 400 (Pentra C400) Clinical Chemistry Analyzer

This is the magnesium measurement reagent for the Pentra 400 / C400. It's distinct from the calibrator and controls used to standardize and monitor the assay. Not for use with non-HORIBA instruments.

FAQs:

What is the Horiba ABX Pentra Magnesium RTU used for?

It's the reagent that measures magnesium on the Pentra 400 / C400 using a photometric xylidyl blue method. Magnesium testing is used to evaluate metabolic and electrolyte disorders and to monitor patients on long-term IV therapy.

What does "RTU" mean?

RTU stands for "ready-to-use" — the reagent requires no reconstitution or preparation before loading on the analyzer.

Does it need refrigeration?

Yes. Store refrigerated at 2–8°C, and the product ships with cold-chain handling.

Which analyzer is P/N 1220001646 compatible with?

The HORIBA ABX Pentra 400 / Pentra C400 clinical chemistry analyzer.

How many tests does one kit provide?

Approximately 200 tests (2 × 25 mL). Actual yield depends on your calibration and QC frequency.

What method does it use?

A photometric (colorimetric) method using xylidyl blue — magnesium forms a colored complex with the dye, measured by the analyzer in proportion to the magnesium concentration.

Is it hazardous?

It carries a GHS hazard classification (shown on the box). Wear appropriate PPE, avoid skin and eye contact, and follow the Safety Data Sheet for handling and disposal.

What's the difference between the box REF and the catalog number?

The box shows REF A11A01646; distributors order it as P/N 1220001646. They're the same product — we list both so you find this page from either number.
