Buffer solution pH 9,00 ±0,01 (20 °C), ROTI®Star, 500 ml, plastic

Buffer solution pH 9,00 ±0,01 (20 °C) is a ready-to-use calibration standard from the ROTI®Star range for accurate pH-value determination in the laboratory. Specified at 20 °C with a tight tolerance of ±0,01, it supports reliable electrode calibration and routine quality control across analytical, research and industrial workflows. Physical data include a density of 1,026 g/cm³ and a boiling point of 100 °C, consistent with an aqueous buffer matrix suited to everyday bench use. This ROTI®Star buffer from manufacturer Carl ROTH is intended for determination of physical properties where stable alkaline reference points are required. Categories of use centre on pH measurement, method validation and instrument checks. Handle and store according to laboratory good practice and consult the accompanying safety documentation before use. The defined pH setpoint and documented density help laboratories maintain traceable calibration sequences without preparing buffers in-house.
