Description
Buffer solution pH 7,00 is a ready-to-use neutral calibration standard supplied in a 500 ml pack for laboratory pH measurement. This WinLab® buffer solution is intended for calibration and verification of pH meters and electrodes across analytical, quality-control and research applications. Prepared to a nominal pH value of 7,00, it provides the central reference point commonly used when adjusting glass electrodes and multiparameter instruments. The 0,5 l nominal volume suits individual workstations and moderate calibration demand. Each batch includes a factory test certificate in accordance with EN 10204-2.3, supporting documented traceability in regulated laboratory settings. Available under the WinLab® brand from manufacturer Windaus, the solution integrates into standard aqueous pH protocols without additional preparation. Laboratories employ pH 7,00 buffers to establish zero points, assess electrode response and confirm instrument readiness before sample analysis. The clear liquid format allows direct transfer into calibration beakers or electrode cups. Appropriate for teaching, industrial and routine laboratory environments that require a reliable neutral buffer reference.

Questions about Buffer solution, pH 7.00, 500ml
What is this article?
Buffer solution, pH 7.00, 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.
