Certified Conductivity Standards in Practical Sachets
In environmental analysis, it is often necessary to perform measurements right out in the field. For your conductivity measurements, we provide ready-to-use sachets especially designed for this purpose.
The practical Certipur® conductivity standards in sachets from Merck are reliable, easy-to-use and always fresh. Certipur® sachets contain certified conductivity standard solutions in small, handy portions suitable for laboratory and external use. Their safe and robust packaging protects them from contamination with micro-organisms, CO2
Merck’s ready-to-use conductivity standards can be used outdoors as well as in laboratories, but their convenience and safety make them ideal for mobile environment analysis. Handling couldn’t possibly be easier: Just open the sachet and start measuring. In principle, you do not even need a beaker. For measurements, the electrode can simply be inserted into the sachet.
And because Certipur® conductivity sachets are produced by Merck, you benefit from maximum precision and reliability. Our laboratory for conductivity measurement has a dual accreditation in accordance with DIN EN ISO / IEC 17025 and ISO Guide 34. Certipur® conductivity standards are measured against our own primary reference standards certified by PTB in Brunswick, the German metrological institute, and against international conductivity standards from NIST (U.S.). Both traceability procedures are documented in a comprehensive, batch-specific Certificate of Analysis.
