Description
Technical buffer solution pH 7,01 is a colour-coded green standard prepared for pH calibration. The nominal value is 7,01 ±0,01 pH at 25 °C, supplied in technical quality and accompanied by a certificate of analysis. Traceability is established to NIST. The solution is filled in a plastic canister of 3,78 L (1 US gallon); the commercial unit is a carton containing 2 canisters. Net weight is 7,7 kg and gross weight is 8,7 kg. This pH buffer from manufacturer Hanna Instruments supports routine electrode and meter calibration around the neutral range. Green colour coding allows rapid visual identification when several buffers are used in sequence. The large canister format suits laboratories and technical facilities that consume calibration solution regularly and prefer documented, technical-grade references. Use is straightforward for two-point or multi-point calibration workflows that require a stable intermediate set point with stated tolerance and analytical documentation.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about 7.01 pH Value @25°C, (2) 1 G (3.78 L) bottle
What is this article?
7.01 pH Value @25°C, (2) 1 G (3.78 L) 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.
