Thermo Fisher, ECBU7BT, Eutech™ pH Buffers and Solutions

Thermo Scientific Eutech pH 7.00 Calibration Buffer is an aqueous reference solution for checking and calibrating laboratory pH meters and glass electrodes near the neutral region. Its nominal pH 7.00 calibration point supports routine two- or three-point pH calibration and helps establish a stable reference before measuring aqueous samples. The 480 mL plastic bottle accommodates repeated laboratory use in chemical analysis, water testing, research and general quality-control workflows. A clean aliquot should be transferred to a suitable calibration vessel to prevent sample carryover into the stock bottle. Rinse the electrode between different buffer values and perform calibration at a temperature appropriate for the meter's compensation settings. For measurements extending into acidic or alkaline ranges, combine this neutral reference with a suitable second buffer rather than relying on a single-point adjustment.
