Regular verification of laboratory instrumentation is of primary importance in a modern manufacturing facility, not only for reasons of quality control but also as an assurance of plant efficiency.  

Depending on the instrument type, application and traceability requirement, a choice can be made from a number of Certified Reference Materials offered by

Bellingham + Stanley, a UKAS accredited calibration laboratory No. 0834, that may be used to verify almost any make of refractometer or polarimeter.

All CRMs are manufactured to the highest standards and are certified in accordance with EN ISO/ IEC 17025:2005; with traceability to ICUMSA and NIST or PTB depending on the CRM type. 

As the United Kingdom Accreditation Service (UKAS) is one of the signatories to the International Laboratory Accreditation Co-operation (ILAC) Arrangement for the mutual recognition of calibration certificates, all certificates issued by

Bellingham + Stanley’s UKAS laboratory will be supported by the ILAC-MRA logo, providing local acceptance of accreditation.
