Electrolytes are used as refill solutions for liquid filled electrodes as well as a storage solution for all types of pH electrodes. With the pepsin cleaning solution, you can remove protein precipitation from the diaphragm of electrodes with liquid electrolyte.
Colour coded. Tested and ISO 17025 Certified at 25 °C. Uncertainty of measurement ±0.02 pH. Temperature dependence data is printed on the label as are lot numbers and expiry dates. These pH buffer solutions are suitable for use where very accurate measurements are required and are supplied with a detailed Certificate of Analysis which outlines traceability to N.I.S.T (the N.I.S.T SRM(s) Lot No. is stated on the certificate). This item has a 12 to 36 month shelf life from date of manufacture depending on pH value.
