pH 7.01 Calibration Solution Sachets
Traditional buffer solutions are packed in 230 mL leak-proof bottles and are recommended for lab applications. Sachets are sealed against light and air and are ideal for on-the-spot calibration, such as when a winemaker needs to measure the pH of a wine batch.
Simply open, insert the tester or electrode into the sachet and calibrate. Thereafter, measure many wines before calibration is necessary
Sachets are sold in boxes of 25 pieces.
