Specified at 20 °C with a narrow ±0,01 tolerance, it enables reliable electrode adjustment, routine instrument checks and analytical quality control at the pH 10 level. Physical properties include a density of approximately 1 g\/cm³ and a boiling point of 100 °C, consistent with an aqueous laboratory buffer. This borate-free ROTI®Star buffer from manufacturer Carl ROTH supports laboratories that require a high-pH calibration point without borate in the formulation. Application areas focus on determination of physical properties, method validation and everyday pH measurement in research, production and teaching environments. Follow standard laboratory handling practice and consult the safety data sheet before use.

The solution exhibits a density of roughly 1 g\/cm³ and a boiling point of 100 °C, consistent with an aqueous buffer matrix. It is delivered as 1 l in a plastic container with a unit weight of about 1,300 kg, suitable for everyday analytical and quality-control use. Phosphate buffers at pH 3.0 are frequently required for sample preparation, pH adjustment and pharmacopoeial procedures that specify this acidic phosphate system. This phosphate buffer solution pH 3.0 from manufacturer Carl ROTH is positioned within the special buffer solutions range linked to European Pharmacopoeia 4.1.3 monographs. The ready-made litre pack helps laboratories avoid multi-step preparation from individual salts while maintaining a clear specification trail. Applications span analytical chemistry benches, method support and related wet-chemistry tasks, including environments that also run liquid chromatography workflows.
