Description
Buffer solution pH 3.00 ±0.01 (20 °C) is a ready-to-use ROTI®Calipure calibration buffer for precise pH measurement in the acidic range. The tight tolerance of ±0.01 at 20 °C supports fine electrode calibration and intermediate check points between strongly acidic and near-neutral standards. Density is approximately 1 g/cm³ and the boiling point is 100 °C, consistent with an aqueous working buffer for laboratory use. This from manufacturer Carl ROTH serves pH-value determination, instrument calibration and routine quality control in analytical environments. Ready-to-use formulation avoids preparation variability and helps laboratories maintain comparable calibration results across shifts and instruments. The one-litre pack supports regular multi-point calibration schemes without excessive waste or oversized containers. Typical applications include physical-property testing and standardised pH buffer workflows where a well-defined pH 3.00 reference at 20 °C is specified. Clear temperature-linked pH labelling assists SOP compliance and correct selection among multi-buffer calibration sets.

Questions about Buffer solution pH 3.00 ±0.01 (20 °C), ROTI®Calipure ready to use, 250 ml
What is this article?
Buffer solution pH 3.00 ±0.01 (20 °C), ROTI®Calipure ready to use, 250 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
