Formulated to provide precise pH determinations, these buffer solutions which are standardised against N.I.S.T. certified reference samples, are ideal for calibrating electrodes and pH meters. The buffer is colour-coded to avoid error and accurate to within ±0.02 pH at 25°C (77°F).
Each buffer contains a preservative/mould inhibitor and a coated foam liner cap to prevent contamination and leakage.
