pH test paper Duotest pH 1–12, with two indicator zones, refill pack CL01.1501.0100 (±)-Atenolol-d7 (N-isopropyl-d7)Duotest indicator papers combine two different indicator zones on a single strip. The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colors and increases the mechanical stability. The refill reels of indicator paper come singly sealed to ensure long term stability and protection against many external influences. They have to be placed in the plastic reel with color scale to be used. Technical Data
