Description
pH buffer solution with N.I.S.T. certificate in Patent bottle is a ready-to-use calibration standard for precise pH measurement and electrode verification in laboratory environments. Formulated to a certified value of 7,00 ± 0,01 at 25 °C, this aqueous buffer supports accurate potentiometric determinations and routine instrument checks. The 250 ml fill is supplied in a practical Patent bottle that facilitates controlled dispensing and secure handling during daily analytical work. Traceability to recognised reference materials is documented by the accompanying N.I.S.T. certificate, enabling compliance with laboratory quality protocols. Produced by manufacturer Hecht, the solution requires no dilution or preparation and delivers consistent response for calibration of pH meters and sensors. Its stable composition suits research, educational and industrial testing workflows where reliable neutral-range buffering is essential. The Patent bottle format further aids contamination control and convenient storage within standard laboratory setups, making the product a practical choice for continuous quality-control applications.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH buffer solution N.I.S.T-Certificate in patent bottle, 250 ml pH 7,00±0,01/25°
What is this article?
pH buffer solution N.I.S.T-Certificate in patent bottle, 250 ml pH 7,00±0,01/25° is the article on this page. Luminix Health distributes Hecht 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.
