Description
Technical buffer solution pH 7,01 is a ready-to-use calibration liquid presented in a 500 ml plastic bottle. Designed for pH electrode and meter calibration, it provides a stated accuracy of ±0,01 pH at 25 °C and is accompanied by a certificate of analysis. The near-neutral 7,01 value is a widely used reference point for two- or multi-point calibration sequences in research, quality control and routine laboratory work. Traceability is referenced to NIST standards. Supplied by manufacturer Hanna Instruments in technical quality, the solution supports consistent day-to-day calibration of pH instrumentation. The 500 ml bottle format is practical for benches with moderate to high calibration frequency, allowing repeated use while remaining easy to handle and store. Net weight is 0,598 kg. Apply the buffer according to standard laboratory pH calibration procedures to establish accurate instrument response around the neutral range. The technical grade and documented analysis make it suitable for general analytical and process monitoring applications requiring a reliable pH 7,01 standard.
This article belongs on 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.
