Description
pH buffer 4,01 in a dispenser bottle is a ready-to-use calibration solution for adjusting and verifying pH measuring instruments. The buffer value of 4,01 provides a defined acidic reference point that is widely used in multi-point calibration routines, enabling laboratories and process users to establish accurate instrument response across the lower pH range. Regular calibration with a stable buffer of known value is essential for trustworthy pH data in quality control, research and routine analytical work. Supplied by manufacturer Testo in a practical dispenser bottle, the solution can be dispensed cleanly and economically, reducing waste and contamination risk compared with open containers. The convenient packaging supports both bench-top use and portable measurement setups where rapid, repeatable calibration is required before sample analysis. Net weight is approximately 0,332 kg per unit. This pH 4,01 buffer is intended for calibration and adjustment of pH meters and probes, helping maintain measurement integrity over successive working days. Suitable for laboratories that rely on standardised buffer points to keep electrodes and instruments within specification.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH buffer solution 4.01
What is this article?
pH buffer solution 4.01 is the article on this page. Luminix Health distributes Testo 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.
