Description
Buffer solution pH 9,00 is a ready-to-use alkaline laboratory reagent for calibration and checking of pH measuring equipment. Offering a defined pH value of 9,00, it establishes a reliable alkaline reference for electrodes, meters and automated pH systems used in analytical and quality-control settings. This variant is supplied in a 1000 ml pack with a nominal volume of 1 l, convenient for higher-throughput benches, shared instrument parks or extended calibration sequences. The product forms part of the WinLab® buffer solutions from manufacturer Windaus and includes a factory test certificate in accordance with EN 10204-2.3, aiding traceable documentation in laboratory quality systems. It is intended for direct use in routine calibration, method validation, aqueous sample work and process-related pH control where a stable pH 9,00 point is specified. The larger volume reduces changeover frequency while remaining practical for standard laboratory handling. Suitable for chemistry, environmental, industrial QC and research laboratories, this WinLab® buffer supports reproducible instrument performance and consistent day-to-day measurement practice without additional preparation steps before use.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution, pH 9.00, 1000ml
What is this article?
Buffer solution, pH 9.00, 1000ml is the article on this page. Luminix Health distributes Windaus 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.
