Description
Buffer solution DuraCal pH 11.00 (25 °C) is a colourless laboratory buffer for reliable pH-value determination and electrode calibration. Defined at pH 11.00 at 25 °C, it provides a stable alkaline reference point for meters, sensors and routine quality-control checks in analytical and process laboratories. The ready-to-use solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C, supporting straightforward handling under standard bench conditions. It is supplied in a 500 ml pack with a net weight of about 0,701 kg, convenient for regular calibration work without frequent bottle changes. Each unit is accompanied by a Hamilton certificate, giving documented assurance for traceable pH calibration. This DuraCal buffer from manufacturer HAMILTON fits applications in physical-property determination, wet chemistry and general laboratory pH measurement. Clear, colourless appearance allows quick visual inspection before use, while the defined pH specification helps laboratories maintain consistent alkaline calibration points across instruments and shifts.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution DuraCal pH 11.00 (25 °C), colourless, with Hamilton certificate
What is this article?
Buffer solution DuraCal pH 11.00 (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.
