Buffer Solution

Reagecon’s pH buffer standards are directly traceable to the IUPAC pH scale by an unbroken chain of traceability.
Reagecon achieve this traceability through a series of comparisons, with the key reference materials being Standard Reference Materials(SRMs) manufactured by NIST.

In addition to the cer tification to ISO9001:2008, Reagecon’s pH analysis is also accredited to ISO 17025 - “Generalrequirements for the competence of testing and calibration laboratories”. Reagecon’s accreditation to ISO17025 givesindependent proof of three key areas:• Our pH analysis is technically valid and is carried out in a thoroughly controlled manner by highly-qualified staf fREAGECON PRICE-LIST 2021• Our claims over the accuracy of our pH analysis are valid and we have properly quantified our accuracy in ourUncer tainty of Measurement calculations.• Our pH analysis is traceable to NIST SRMs. It is impor tant to note that NIST do not police claims of traceability to theirSRMs. Any manufacturer of pH buf fers can claim that their buf fers are traceable to NIST, but only manufacturers thatare accredited to ISO17025 have independent proof of their traceability.Reagecon’s accreditation is indicated by the Irish National Accreditation Board (INAB) logo on our Cer tificates of Analysisfor pH Buf fers. Accreditation by INAB and all other accreditation boards validated to accredit ISO 17025 are mutuallyrecognised as being directly equivalent.
