pH Buffer Solution for pH meter calibration

Formulated to provide precise values, these ph buffer solutions which are standardised against certified reference samples, are ideal for electrodes and pH meters calibrations. The buffers are colour-coded to avoid error and accurate to within ±0.01 pH at 25°C. Each buffer contains a preservative/mould inhibitor and a shrink-sealed cap to prevent contamination and leakage. Temperature compensation charts are included with each pH buffer solution. The shelf life of the buffer solution is 40 months from date of manufacture.
