Description
Universal indicator sticks pH-Fix are laboratory test sticks for determining pH in the range 0.3 to 2.3. Presented in a square plastic box, these sticks offer a practical format for rapid pH checks on strongly acidic samples in analytical and teaching laboratories. The pack contains 100 pc(s), giving users a ready stock for frequent measurements. Belonging to the pH-Fix series from manufacturer ROTH SELECTION, the sticks sit within the established family of pH papers and pH indicators used alongside measuring instruments for pH value work. Each pack weighs 0,034 kg, so the compact square plastic box stores easily on the laboratory bench or in a drawer. The defined measuring window of pH 0.3–2.3 allows selection of the correct stick type when samples are expected to lie in the lower acidic region. Categories of application include general labware and pH measurement setups where a straightforward indicator stick is preferred for orientation testing. The square plastic packaging keeps the sticks organised and protected until required. Laboratories performing routine acidity screening can incorporate these universal indicator sticks into their standard pH-testing materials.
This article is part of pH meters, in pH & electrochemistry.

Questions about Universal indicator sticks pH-Fix, in square plastic box, pH 0.3-2.3
What is this article?
Universal indicator sticks pH-Fix, in square plastic box, pH 0.3-2.3 is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Lab instruments.
A pH meter reads the electrode and displays pH, after calibration with at least two buffers. A meter that cannot be calibrated is a voltmeter. Resolution to 0.001 is not the same as accuracy. Portable and benchtop meters differ in the electrodes they accept and in the data they store.
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.
