General pH Calibration Bundle, pH 4 & 7, General Purpose Cleaning Solution, Electrode Storage Solution (Satchets)

The General Calibration Bundle is great for customers who value field calibration and more importantly, fresh buffers. This bundle has the added value of being able to ensure fresh buffer every time you calibrate for accurate results and expires after 5 years from manufacturing. Includes 4.01 & 7.01 pH Buffer Sachets (25 pieces each); Electrode Storage Solution (500 mL); General purpose Cleaning Solution Sachet (25 x 25 mL).

Buffer solutions are prepared according to priecise formulas and are standardized with a pH meter and electrode calibrated with NIST standards. A Certificate of Analysis (COA) is available upon request for ultimate traceability.
