Description
Buffer tablets pH 7 are solid laboratory reagents for preparing neutral reference buffer solutions used in pH-value determination and electrode calibration. They support reliable mid-scale checks on pH meters and sensors in analytical, quality-control, research, and educational settings where a stable pH 7 reference is essential. The tablet presentation reduces handling of bulk liquid buffers and helps keep storage compact while remaining practical for frequent daily calibration. Each unit is supplied as 100 pc(s) with a pack weight of 0,100 kg, matching routine laboratory consumption patterns. Classed among pH buffer solutions for determination of physical properties, these tablets are suited to method verification, instrument adjustment, and general laboratory pH control around the neutral point. Available from manufacturer ROTH SELECTION, they integrate easily into standard physical-property measurement workflows. Used according to normal laboratory practice for buffer tablets, they offer a convenient route to reproducible neutral-range calibration without preparing multi-component mixtures from individual chemicals, supporting consistent results across varied bench and teaching applications.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about Buffer tablets pH 7, 100 unit(s)
What is this article?
Buffer tablets pH 7, 100 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Lab chemicals.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
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.
Which category should I open next?
The category is Buffers & pH solutions. The sub-category is Biological buffers (Tris, HEPES, MOPS). The catalogue is Lab chemicals.
