Metrohm has announced that its buffer solutions are compliant with GLP and ISO 9000 requirements.
Each buffer comes labelled with shelf life, batch number, date of production, measured pH value and the temperature effect on the buffer solution.
This temperature effect is stored in Metrohm titrators and pH meters.
Customers can select from individual buffer sachets, buffer bottles or concentrated buffers, and all are NIST-traceable.
