Horiba ABX Pentra ISE Standard 2 – 280 mL – Pentra 400 / C400 (P/N 1220001718)

What is it:

The Horiba ABX Pentra ISE Standard 2 is a genuine HORIBA calibration solution for the ABX Pentra 400 / Pentra C400 clinical chemistry analyzer's Ion-Selective Electrode (ISE) module. It's supplied as a ready-to-use 280 mL bottle and is for professional in vitro diagnostic use.

Part numbers:

• Catalog P/N: 1220001718
• Box REF: A11A01718

What it's used for:

ISE Standard 2 is one of the two known-concentration solutions the Pentra 400 uses to calibrate its electrolyte module. The module measures Sodium, Potassium, and Chloride by potentiometry, and it determines each electrode's slope using two standards of known concentration — Standard 1 and Standard 2. Calibrating against these standards is what keeps Na/K/Cl results accurate over time. Because the ISE module is recalibrated routinely, this is a regularly reordered reagent — and it's used together with ISE Standard 1 (P/N 1220001717).

What's included:

• 1 × ABX Pentra ISE Standard 2, 280 mL
• Catalog P/N: 1220001718 · Box REF: A11A01718
• Ready-to-use ISE calibration solution
• For professional in vitro diagnostic (IVD) use only
• Manufactured by HORIBA ABX SAS, France

Compatible analyzer:

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

This is ISE Standard 2, one of two calibration standards for the Pentra 400 / C400 ISE module — it works together with ISE Standard 1 (P/N 1220001717). It is a calibration solution, not a reference solution, cleaner, or QC control. Calibration requires both standards. Not for use with non-HORIBA instruments.

FAQs:

What is the Horiba ABX Pentra ISE Standard 2 used for?

It's one of two calibration solutions for the Pentra 400 / C400 ISE module. The module uses Standard 1 and Standard 2 — both at known concentrations — to determine each electrode's slope and keep Sodium, Potassium, and Chloride results accurate.

Which analyzer is P/N 1220001718 compatible with?

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

Do I need Standard 1 as well?

Yes — ISE calibration uses both standards. Standard 1 (P/N 1220001717) and Standard 2 (P/N 1220001718) are separate products, both required to calibrate the module. Many labs keep both on hand.

Is this the same as the ISE Reference Solution?

No. Standard 1 and Standard 2 are calibration solutions; the Reference Solution (P/N 1220001901 / 1220001719) bathes the reference electrode to provide the measurement baseline. They're different ISE reagents — order what your procedure calls for.

How much is in one bottle?

This is the 280 mL bottle.

Does it need refrigeration?

Storage is listed on the bottle label — follow the temperature shown there. Contact us with any handling questions.

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

The bottle label shows REF A11A01718; distributors order it as P/N 1220001718. They're the same product — we list both so you find this page from either number.
