Description
Buffer solution pH 2.2 is a ready-to-use analytical buffer specified as Reag. Ph. Eur. 4.1.3 for laboratory work that depends on a defined acidic medium at pH 2.2. Density is approximately 1 g/cm³, matching dilute aqueous buffer preparations under standard laboratory conditions. The solution is offered in a 1 l plastic pack intended for routine pH adjustment and reference procedures connected with European Pharmacopoeia chapter 4.1.3. This buffer from manufacturer Carl ROTH forms part of the special pH-buffer solutions range used in analytical chemistry when a stable pH 2.2 setpoint is required. Source data identify the preparation under designation 4010500. Unit quantity is 1 liter, and the filled pack weight is stated as 1,300 kg, which supports straightforward storage, transport, and bench use. Laboratories engaged in pharmacopoeia-related testing and broader analytical workflows can apply this buffer wherever controlled acidity at pH 2.2 is specified. Handling characteristics remain those of a typical dilute aqueous buffer, aiding consistent performance in controlled laboratory environments without additional formulation steps.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution pH 2.2
What is this article?
Buffer solution pH 2.2 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.
