Description
Buffer solution pH 4.62 ±0.01 (20 °C) is a ready-to-use aqueous calibration standard for accurate pH-value determination in analytical and quality-control laboratories. Part of the ROTI®Calipure range, it provides a defined reference of pH 4.62 with a tolerance of ±0.01 at 20 °C, supporting electrode calibration and routine instrument checks. Manufacturer data list a density of 1,005 g/cm³ and a boiling point of 100 °C, consistent with a water-based laboratory buffer. The solution is filled as 1 l in a plastic bottle, giving a practical working volume for repeated calibration without on-site preparation. This buffer solution from manufacturer Carl ROTH is suited to determination of physical properties, environmental testing, process monitoring and life-science workflows that require a slightly acidic reference point. Ready-to-use presentation shortens setup time and helps limit handling differences between operators. Clear temperature specification at 20 °C allows laboratories to align measurement conditions with the stated pH value during calibration and verification sequences across benchtop pH meters and related systems.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Buffer solution pH 4.62 ±0.01 (20 °C), ROTI®Calipure ready to use, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth 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.
