Description
The L 4791 is a DIN buffer solution at pH 1,68 supplied in FIOLAX® ampoules for accurate pH electrode calibration and verification. Each package contains 60 ampoules of sterilised buffer, accompanied by a manufacturer certificate to support traceable laboratory use. The FIOLAX® glass ampoule format protects the solution until opening and is convenient for single-use aliquots, reducing contamination risk during calibration sequences. With a defined pH value of 1,68, this buffer is suited to the acidic end of multi-point calibration protocols on laboratory pH meters and combination electrodes. Offered as one package from manufacturer SI Analytics – a Xylem brand, L 4791 supports routine quality control, method validation and instrument checks where certified DIN buffer material is required. Sterilisation of the contents and the sealed ampoule presentation help maintain solution integrity from storage through to the moment of use in analytical and research laboratories performing precise pH work.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
L 4791, Buffer solution in FIOLAX® ampoules, 60 ampoules, DIN buffer solution pH is the article on this page. Luminix Health distributes SI Analytics - 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.
