CS526 ISFET pH Probe

• Proteins, fats, and oils may be removed by scrubbing in a solution of Terg-A-

Zyme (Alconox company), a pepsin solution, or a similar product.

Afterwards, rinse thoroughly with deionized or distilled water.

• Do not use hydrofluoric acid, acetone, MEK, or similar agents to clean the

probe.

9.1.3 Revitalizing

Revitalization is performed to regenerate the diaphragm in the pH probe. For best

results, clean the probe first as described in Section 9.1.2, Cleaning Procedure,

before revitalizing.

1. Make sure the probe is warm (around 60°C).

2. Place the probe directly (without flushing it with deionized water or cooling it

down) in a saturated KCl-solution (pn #16349) at room temperature and keep

it in the solution for 20 minutes.

This cold KCl-dip will regenerate the reference system and the diaphragm.

9.2 Storage

9.2.1 Short-Term Storage (2 days or less)

1. Clean the probe first with water and possibly a mild detergent.

2. Place it in a clean container with fresh pH7 buffer solution (pn 25586) to

prevent contamination of the probe directly after cleaning.

9.2.2 Long-Term Storage (more than 2 days)

1. Clean the probe first with water and possibly a mild detergent.

2. Place one drop of demi-water in the probe’s protective cap.

3. Place the protective cap on the probe tip.

Always revitalize and recalibrate the probe before using it

again after long term storage (see Section 9.1.3, Revitalizing,

and Appendix C

, Calibration).
