Whether for training purposes, for checking and in order to support the calibration of instruments or for internal method checks: you can rely on our reference materials. Our samples have been qualified within the scope of proficiency tests and checked for constancy of values at regular intervals.
Each sample set contains at least two different samples to determine results at more than one level. This increases your certainty of not only measuring precisely, but also correctly!
Our reference materials catalogue will be online shortly. In the meantime, please do not hesitate to contact us.
