pH 4.01 Calibration Buffer Solution- Box of 25 Sachets of 20 ml each. The use of calibration and cleaning solutions is fundamental for the correct use of electrodes and for obtaining the most accurate and reproducible readings. Often readings are not correct because the sensors have not been properly handled. Milwaukee standard solutions are available in 230 mL bottles and 20 mL 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 onthe-spot calibration. Simply open, insert the tester or electrode into the sachet and calibrate. Sachets are sold in boxes of 25 pieces.
