Description
TEP 4/25 is a technical buffer solution with a pH value of 4,01, supplied in a bulk pack of twenty-five 1-litre bottles. This acidic buffer is used for calibration and verification of pH measuring equipment in the lower range, providing a practical solution for laboratories and technical facilities with high calibration demand. Every bottle contains 1000 ml of ready-to-use technical buffer, allowing efficient electrode checks across multiple instruments or extended operating periods. The product belongs to the TEP line of technical buffer solutions and carries the WTW ® registered mark from manufacturer WTW - a Xylem brand. The full pack weighs 25,2 kg net and 28 kg gross, reflecting the larger multipack format. Preference origin marking is confirmed, and the goods originate from Germany. Well suited to quality-control laboratories, industrial process analytics and environmental monitoring sites that rely on consistent technical buffers at pH 4,01 for routine meter and electrode maintenance.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about TEP 4/25, Technical buffer solution pH = 4.01; Box with 25 bottles with 1 liter
What is this article?
TEP 4/25, Technical buffer solution pH = 4.01; 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.
