Description
Buffer solution pH 7.00 is a ready-to-use neutral calibration buffer for accurate adjustment and checking of pH meters and electrodes. Defined at pH 7,00, it serves as the central reference point in single-, two- and multi-point calibration schemes used throughout analytical and quality-control laboratories. The product is supplied in a 250 ml bottle that is practical for daily bench work, instrument start-up checks and periodic electrode verification. Net weight and gross weight are both 0,299 kg, reflecting a compact, easy-to-handle unit. Offered by manufacturer Mettler-Toledo OnLine, this neutral standard belongs to the well-known range of pH buffer solutions employed in chemistry, biotechnology and industrial measurement. A reliable pH 7 reference supports correct slope evaluation when paired with acidic and alkaline buffers and helps maintain stable sensor performance over time. The single-bottle format fits individual meters as well as shared laboratory stations. Suitable for aqueous sample workflows that depend on a clearly defined neutral calibration point.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Certified buffer pH 7.00, 250mL
What is this article?
Certified buffer pH 7.00, 250mL is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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.
