Description
Buffer solution pH 4,01 is a technical pH buffer for reliable calibration of pH electrodes and meters in laboratory workflows. The coloured formulation makes different pH values easy to distinguish at a glance, reducing mix-ups during multi-point calibration. Supplied in a practical 1000 ml working and storage bottle with an integrated small vessel, it allows direct calibration without transferring liquid into a separate beaker. The nominal volume is 1 l and the stated pH value is 4,01, matching common acidic calibration points used in analytical chemistry, quality control and process monitoring. This Winlab® buffer from manufacturer Windaus is designed for everyday technical use where clear identification and convenient handling matter. The bottle format supports both bench work and intermediate storage of the remaining solution. Ideal for laboratories that calibrate pH instruments regularly and prefer coloured technical buffers in a ready-to-use litre pack for efficient, organised electrode checks.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Technical buffer solutions, pH 4,01, 1000ml
What is this article?
Technical buffer solutions, pH 4,01, 1000ml is the article on this page. Luminix Health distributes Windaus 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.
