Description
Buffer solution DuraCal pH 1,09 (25 °C) is a ready-to-use pH reference buffer for calibration and verification of pH measurement systems. The colourless solution is specified at pH 1,09 at 25 °C and is supplied with a Hamilton certificate, supporting documented traceability in laboratory quality systems. Packed as a 500 ml unit, it shows a density of approximately 1 g/cm³ and a boiling point of 100 °C. This acidic buffer is suited to electrode calibration, routine checks and method control wherever low-pH reference points are required in research, quality control or process laboratories. Clear appearance aids visual inspection before use on meters, electrodes and automated pH systems. The DuraCal buffer from manufacturer HAMILTON is intended for determination of physical properties in pH-value workflows and is classified under UN number 1789. Analysts can integrate it into daily calibration sequences to maintain accurate, reproducible pH readings at the stated reference value without additional preparation steps.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution DuraCal pH 1.09 (25 °C), colourless, with Hamilton certificate
What is this article?
Buffer solution DuraCal pH 1.09 (25 °C), colourless, with Hamilton certificate is the article on this page. Luminix Health distributes HAMILTON 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.
Which category should I open next?
The category is Buffers & pH solutions. The sub-category is pH buffers & conductivity standards. The catalogue is Lab chemicals.
