Description
pH buffer 7,00 in a dispenser bottle is a ready-to-use calibration solution for adjusting and verifying pH measuring instruments at the neutral reference point. The buffer value of 7,00 is a standard midpoint used in single- and multi-point calibration protocols, allowing users to check and correct instrument offset before critical measurements. Accurate calibration with a defined neutral buffer underpins reliable pH data in laboratory analysis, quality assurance and process monitoring. This solution from manufacturer Testo is supplied in a practical dispenser bottle that enables clean, controlled dosing and helps minimise contamination and unnecessary consumption. The format suits both fixed laboratory workstations and mobile measurement kits where quick, repeatable calibration steps are needed. Net weight is approximately 0,335 kg per unit. Intended for calibration and adjustment of pH meters and electrodes, the pH 7,00 buffer supports consistent instrument performance across successive measurement series. It is a practical choice for laboratories and technical users who maintain standardised buffer points as part of routine electrode and meter care.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH buffer solution 7.00
What is this article?
pH buffer solution 7.00 is the article on this page. Luminix Health distributes Testo 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.
