After the first 4 minutes polarity should be changed. c) With the 3400 series the sample is heated in 0.1 N NaCl for 20 minutes at +100 °C, but with the 3100 series at +80-90 °C. Afterwards the surface resistance per unit is determined. • Electrodialysis membranes have always to be kept wet and should be stored in a 3 % NaCl solution in a cool and dark place. • Chemical stability: Good chemical stability in neutral solutions, in acid solutions (ph 0-7) and in alkaline solutions (ph 7-11) Fair chemical stability in alkaline solutions (ph 11-14) an to mild oxidizing agents Poor chemical stability to reducing agents Technical specification • Electrical resistance: 15 Ohm/cm 2 (0.1 N NaCI); 6 Ohm/cm 2 (1.0 N NaCI) • Permeability: 96 % (0.5 N NaCI/1.0 N NaCI) • Water permeability:
