Description
TEP 7/25 technical buffer solution pH = 7,00 is a ready-to-use technical grade pH buffer supplied as a multipack of 25 bottles, each containing 1 litre. It provides a stable neutral reference point for routine calibration and verification of pH electrodes and meters in laboratory and process environments. The complete pack has a net weight of 26,1 kg and a gross weight of 29 kg, supporting high-throughput workflows that require frequent electrode checks. Belonging to the TEP product line of technical buffer solutions in 1000 ml format, the solution carries the WTW® registered trademark and is manufactured by WTW - a Xylem brand. Each sealed bottle can be opened individually, reducing contamination risk and simplifying stock management across multiple measuring stations. The buffer is suited to chemical, environmental and industrial applications where technical accuracy is sufficient for day-to-day quality control. Originating from Germany, this multipack configuration minimises handling frequency while ensuring consistent availability of fresh calibration medium for reliable pH measurement performance.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about TEP 7/25, Technical buffer solution pH = 7.00; Box with 25 bottles with 1 liter
What is this article?
TEP 7/25, Technical buffer solution pH = 7.00; Box with 25 bottles with 1 liter 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.
