Horiba ABX Pentra Potassium Electrode (ISE) – Pentra 400 / C400 (P/N 3014029450)

What is it:

The Horiba ABX Pentra Potassium Electrode is a genuine HORIBA Ion-Selective Electrode (ISE) for the ABX Pentra 400 / Pentra C400 clinical chemistry analyzer. It's the potassium (K⁺) electrode for the analyzer's ISE module, supplied ready-to-use as a single electrode.

Part numbers:

• Catalog P/N: 3014029450
• Box REF: A11A01740

What it's used for:

The potassium electrode measures potassium (K⁺) in patient samples on the Pentra 400's ISE module. The module determines electrolytes by potentiometry — it reads the electrical potential between this ion-selective electrode (bathed in sample) and the reference electrode (bathed in reference solution). Potassium is a core electrolyte in routine metabolic panels, so this electrode sees continuous use. As a consumable with a finite service life, it's replaced periodically to keep K⁺ results accurate.

What's included:

• 1 × ABX Pentra Potassium Electrode (ISE), ready-to-use
• Catalog P/N: 3014029450 · Box REF: A11A01740
• Genuine HORIBA service part
• For the ISE module of the Pentra 400 / Pentra C400 analyzer

Compatible analyzer:

• ABX Pentra 400 (Pentra C400) Clinical Chemistry Analyzer (ISE module)

This is the potassium (K⁺) electrode — one of four electrodes in the Pentra 400 ISE module. The others are the Sodium (3014029448), Chloride (3014029449), and Reference (3014029451) electrodes, each a separate part. Order the specific electrode you need. Not for use with non-HORIBA instruments.

FAQs:

What is the Horiba ABX Pentra Potassium Electrode used for?

It measures potassium (K⁺) in patient samples on the Pentra 400 / C400 ISE module, by potentiometry, against the module's reference electrode. Potassium is a standard electrolyte in routine metabolic testing.

Which analyzer is P/N 3014029450 compatible with?

The HORIBA ABX Pentra 400 / Pentra C400 clinical chemistry analyzer, specifically its ISE (Ion-Selective Electrode) module.

How is the potassium electrode different from the other ISE electrodes?

The ISE module uses four electrodes. The Sodium (3014029448), Potassium (3014029450), and Chloride (3014029449) electrodes each measure their specific ion; the Reference electrode (3014029451) provides the baseline they're measured against. They're separate parts — order the one you need.

Does it need refrigeration?

No. Store at room temperature, 15–35°C, per the label.

How do I know when to replace it?

ISE electrodes have a finite service life and degrade with use. Signs include ISE calibration failures, drifting or out-of-range potassium results, and potassium-related error codes. Follow your Pentra 400 ISE maintenance schedule and replace the electrode when calibration or QC indicates end of life.

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

The unit label shows REF A11A01740; distributors order it as P/N 3014029450. They're the same product — we list both so you find this page from either number.
