Description
Buffer solution pH 9,00 is a ready-to-use alkaline calibration reagent for laboratory pH measurement. With a defined pH value of 9,00 it provides a stable reference point for adjusting and verifying pH meters, electrodes and related analytical systems. The solution is supplied in a 500 ml pack with a nominal volume of 0,5 l, suited to routine bench work and multi-instrument calibration schedules. It belongs to the WinLab® buffer solution range from manufacturer Windaus and is delivered with a factory test certificate according to EN 10204-2.3, supporting documented quality control in regulated and research laboratories. Typical applications include daily instrument calibration, method verification, aqueous sample analysis and process monitoring where an alkaline buffer point is required. The ready-to-use liquid format allows direct immersion of electrodes without further preparation, helping laboratories maintain consistent calibration chains across operators and shifts. This WinLab® pH 9,00 buffer integrates into standard laboratory workflows for chemistry, environmental testing, life-science support and quality assurance, offering a practical pack size for regular use while keeping handling straightforward at the bench.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution, pH 9.00, 500ml
What is this article?
Buffer solution, pH 9.00, 500ml 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.
