Description
pH Buffer Solution with Certificate of Analysis is a ready-to-use laboratory standard supplied as a pack of 20 individual sachets, each containing 25 ml of solution buffered to pH 7,00 ± 0,01 at 25 °C. The single-use sachet format ensures that every portion remains sealed and uncontaminated until the moment of opening, supporting accurate calibration and verification of pH meters and electrodes. Pre-measured volumes eliminate the need for dilution or additional preparation steps, reducing handling time and the risk of volumetric errors in routine analytical work. This buffer is suitable for quality-control laboratories, research facilities and educational environments that require traceable pH reference points. Manufactured by Hecht, the product is accompanied by a Certificate of Analysis that documents the stated value and supports laboratory quality systems. The compact sachets are easy to store, open and pour, allowing rapid set-up of calibration sequences without glassware contamination. Consistent performance across multiple uses makes the solution a practical choice for daily electrode checks and multi-point calibrations. The formulation maintains its specified pH under normal laboratory conditions, providing reliable results for chemical, environmental and life-science applications that depend on precise pH measurement.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH buffer solution with certificate of analysis, package with 20 bags of 25 ml
What is this article?
pH buffer solution with certificate of analysis, package with 20 bags of 25 ml is the article on this page. Luminix Health distributes Hecht 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.
