Description
Technical buffer solution pH 7,01 is a colour-coded green calibration standard supplied in a 500 ml plastic bottle. It is intended for pH meter and electrode calibration and offers a stated accuracy of ±0,01 pH at 25 °C, together with a certificate of analysis. The green colour coding aids rapid visual identification on the bench and helps reduce mix-ups when several buffer values are in use. Traceability is referenced to NIST standards. This technical-quality preparation from manufacturer Hanna Instruments supports routine multi-point calibration workflows in laboratories and process environments that rely on a stable near-neutral reference. The 500 ml bottle volume suits regular calibration schedules without excessive bulk. Net weight is 0,6 kg. Use the solution in accordance with standard pH calibration practice to verify instrument performance around pH 7,01. Colour coding, documented analysis and technical grade combine to provide a practical, clearly identifiable buffer for everyday quality control, teaching and analytical applications requiring a reliable green-coded pH 7,01 standard.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about 7.01 pH Value @25°C, (1) 500 mL bottle
What is this article?
7.01 pH Value @25°C, (1) 500 mL bottle 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.
