A comprehensive range of pH Buffer Solutions. Every pH Buffer Solution is traceable to the IUPAC pH scale by an unbroken chain of traceability. This traceability through a series of comparisons, with the key reference materials being Standard Reference Materials (SRMs) manufactured by NIST.

Our diverse array of pH Buffer Solutions these include pH tested at 20°C and 25°C, High Resolution Buffers, Low Ionic Strength Buffers and pH Buffer Capsules. We are excited to add several new additions to our range including buffers to calibrate Antimony Electrodes and Colour Coded pH Buffers with a three decimal place specification. All are manufactured to exacting specifications with an extended shelf life and cover the pH range of pH 1.00 to pH 13.00 inclusive.
