Description
Buffer solution pH 9,18 is a standard-quality calibration buffer for accurate pH electrode adjustment in laboratory and field work. Each pack contains 25 single-use sachets of 20 ml, delivering an accuracy of pH ±0,01 and supplied with a certificate of analysis for documented quality control. Traceability to NIST standards supports reliable alkaline calibration points on pH meters and related instrumentation. The sealed sachet format limits contamination and atmospheric influence until the moment of use, which is practical for routine bench calibration as well as measurements away from the main laboratory. From manufacturer Hanna Instruments, this buffer suits analytical chemistry, quality assurance, environmental testing and teaching laboratories that need a consistent pH 9,18 reference. Net weight is 0,65 kg and gross weight 1,65 kg per pack. Ready-to-use sachets simplify handling, reduce waste from open bottles and help maintain reproducible calibration results across instruments and operators whenever an alkaline buffer point is required.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Buffer Calibration Solution pH 9.18, 25 x 20 mL Sachets, Certificate of Analysis is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Lab chemicals.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
