Description
Buffer solution DuraCal pH 1.68 (25 °C) is a colourless, ready-to-use calibration standard for precise pH-value determination in analytical and quality-control laboratories. Formulated for electrode and meter calibration at the stated acidic reference point of pH 1.68 measured at 25 °C, it supports reproducible physical-property measurements. The solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C, and is supplied in a practical 500 ml pack with a net weight of 0,701 kg. Each unit is accompanied by a DAkkS certificate, enabling documented, traceable calibration workflows. This DuraCal buffer from manufacturer HAMILTON is intended for routine use in pH determination, method validation, and instrument checks across research, industrial, and environmental laboratories. Its clear appearance and defined reference value help maintain measurement consistency during repeated calibration cycles, making it a dependable choice wherever an acidic buffer standard at pH 1.68 (25 °C) is required for accurate electrode performance verification.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution DuraCal pH 1.68 (25 °C), colourless, with DAkkS certificate
What is this article?
Buffer solution DuraCal pH 1.68 (25 °C), colourless, with DAkkS 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?
