Lab-Grade Buffer Solution pH 1.68

This laboratory-grade buffer solution provides a precise pH 1.68 reference for calibrating pH meters and electrodes. It is intended for technicians and quality-control staff who require traceable, NIST-certified standards in analytical workflows. The 500 mL plastic bottle delivers sufficient volume for routine laboratory use.

Storage Stability and Handling

The solution carries a 24-month shelf life when stored under normal laboratory conditions. It is classified as not regulated for transport, so no special hazardous-materials shipping procedures apply. The plastic container resists breakage during daily bench handling.

Consistent Performance During Extended Use

NIST calibration certification ensures the pH value remains reliable across repeated measurements over the product's rated life. The buffer maintains its specified concentration during prolonged calibration sessions without rapid drift. Users who need larger volumes or a different pH point will require additional bottles.

Questions about this item

How do I install this pH 1.68 buffer solution for calibration?

Open the 500 mL plastic bottle, rinse the electrode with deionised water, immerse it in the solution, allow the reading to stabilise, then rinse again before measuring samples. The step often missed is the second rinse, which prevents carry-over.

What maintenance or replacement will this buffer need later?

The solution carries a 24 mo shelf life from manufacture; once opened, contamination shortens usable life, so replace the bottle when the expiry date passes or if the liquid appears cloudy.

What limit appears first during sustained calibration use?

The 500 mL volume is the practical limit — frequent electrode rinsing and daily checks consume the buffer, so a busy lab will exhaust the bottle before the 24 mo shelf life expires.
