Description
TPL 7/25 is a technical buffer solution with a nominal pH value of 7,00, delivered as a multipack containing twenty-five bottles of 250 ml each. This neutral reference buffer is widely used for the calibration and verification of pH electrodes and measuring instruments in laboratory and field settings. The ready-to-use solution provides a stable midpoint calibration standard that is essential for accurate two-point or multi-point pH adjustments across the working range. As part of the TPL series of technical buffer solutions, the product carries the WTW® registered trademark and is manufactured by WTW - a Xylem brand. The full pack weighs 6,75 kg net and 7,5 kg gross, offering an economical supply for facilities that perform frequent electrode calibrations. Individual 250 ml bottles facilitate clean handling and reduce the risk of cross-contamination during daily laboratory work. TPL 7/25 is well suited to quality-control laboratories, environmental monitoring stations and industrial process laboratories that require a dependable technical buffer at pH 7,00 for routine instrument maintenance.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
TPL 7/25, Technical buffer solution pH = 7.00; Box with 25 bottles with 250 ml e is the article on this page. Luminix Health distributes WTW - a Xylem brand 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.
