Buffer solution DuraCal pH 9.21 (25 °C) provides a defined alkaline calibration point for precise pH measurement and instrument verification. Rated at 25 °C and tinted blue for immediate recognition at the bench, it is intended for routine multi-point calibration of pH electrodes and meters. A DAkkS certificate accompanies the solution, supporting traceable documentation in quality systems and accredited laboratories. Typical physical data include a density of about 1 g/cm³ and a boiling point of 100 °C. The 500 ml unit quantity is convenient for repeated calibrations in analytical, process-control, and teaching settings. This DuraCal buffer from manufacturer HAMILTON is well suited to alkaline-range checks during determination of physical properties and dedicated pH-value work. Clear colour coding reduces mix-ups between standards, while the certified composition helps laboratories maintain stable reference performance across measurement campaigns in research, industrial QC, and environmental analysis.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution DuraCal pH 9.21 (25 °C), tinted BLUE, with DAkkS certificate
What is this article?
Buffer solution DuraCal pH 9.21 (25 °C), tinted BLUE, 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 Chemicaliën.
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 Chemicaliën.

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
