Description
TEP 4 technical buffer solution is a ready-to-use pH buffer supplied in a 1 l bottle and adjusted to pH 4,01 for laboratory calibration and control applications. As a technical-grade buffer it is intended for routine pH meter calibration, electrode verification and quality-control checks in analytical and process environments. The solution is delivered as a single 1000 ml unit with a net weight of 0,972 kg and a gross weight of 1,08 kg, offering practical bulk volume for regular laboratory use. Carrying the WTW ® registered trademark and available from manufacturer WTW - a Xylem brand, TEP 4 forms part of the TEP technical buffer solution series. Its defined pH value of 4,01 provides a reliable acidic reference point for instrument standardisation and measurement system checks. The bottle format supports direct use at the bench or with automated systems and suits laboratories that need consistent technical buffers without further preparation.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about TEP 4, Technical buffer solution, 1 bottle with 1 l: pH 4.01
What is this article?
TEP 4, Technical buffer solution, 1 bottle with 1 l: pH 4.01 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.
