Horiba ABX Pentra CO2 RTU Reagent – ~200 Tests – Pentra 400 / C400 (P/N 1220001645)

What is it:

The Horiba ABX Pentra CO2 RTU (P/N 1220001645, REF A11A01645) is a genuine HORIBA ready-to-use (RTU) reagent for measuring total CO2 (bicarbonate / HCO₃⁻) on the ABX Pentra 400 / Pentra C400 clinical chemistry analyzer. It uses an enzymatic method and is supplied as a ready-to-use bi-reagent kit (2 × 20 mL, R1 and R2 bottles), good for approximately 200 tests. For professional in vitro diagnostic use.

Part numbers:

• Catalog P/N: 1220001645
• Box REF: A11A01645

What it's used for:

CO2 RTU measures total carbon dioxide (bicarbonate) in serum and plasma — a core component of the electrolyte panel used to assess a patient's acid-base balance and metabolic status. The assay uses an enzymatic method: bicarbonate is consumed in a phosphoenolpyruvate carboxylase reaction coupled to malate dehydrogenase, producing a measurable change in NADH absorbance at 340 nm, proportional to the CO2 concentration. As a routine electrolyte-panel test, this is a regularly reordered reagent, used together with the CO2 calibrator (P/N 1220001648) and appropriate controls.

What's included:

• 1 × ABX Pentra CO2 RTU bi-reagent kit (2 × 20 mL, R1 and R2)
• Approximately 200 tests
• Manufactured by HORIBA ABX SAS

Compatible analyzer:

• ABX Pentra 400 (Pentra C400) Clinical Chemistry Analyzer

This is the CO2 measurement reagent for the Pentra 400 / C400. It is distinct from the CO2 Calibrator (P/N 1220001648, which standardizes the assay) and from controls (which verify QC). Order the CO2 item your task requires. Not for use with non-HORIBA instruments.

Storage & shipping note:

Store refrigerated (2–8°C). Ships cold-chain with priority handling. Non-returnable once shipped.

FAQs:

What is the Horiba ABX Pentra CO2 RTU used for?

It's the reagent that measures total CO2 (bicarbonate) on the Pentra 400 / C400 using an enzymatic method. Total CO2 is part of the electrolyte panel and is used to assess acid-base balance and metabolic status.

What does "RTU" mean?

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

Which analyzer is P/N 1220001645 compatible with?

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

How many tests does one kit provide?

Approximately 200 tests (2 × 20 mL). Actual yield depends on your calibration and QC frequency.

Is this the reagent or the calibrator?

This is the reagent that runs the CO2 test. The CO2 Calibrator (P/N 1220001648) is a separate product used to calibrate the assay. Most labs need both — order the one your task requires, or both if you're setting up the test.

Does it need refrigeration?

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

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

The box shows REF A11A01645; distributors order it as P/N 1220001645. They're the same product — we list both so you find this page from either number.
