Bluelab 7.0 pH Calibration Solution

Regular cleaning and calibration of pH instruments is essential for accurate readings. First, calibrate the equipment to pH 7.0 (buffer) and then to pH 4.0 (slope). This is necessary for all Bluelab pH products and the calibration of Bluelab pH Probes. To maintain accuracy, avoid cross-contamination, use a smaller plastic cup to transfer solutions, discard samples after use, and store the solutions in a cool, dark place with the lid secured tightly.  It is important to keep Bluelab solutions away from children as they are NIST certified and manufactured specifically for Bluelab products, ensuring longer lasting and accurate results.
