Our ion selective electrodes are highly stable, accurately measuring calcium, potassium, hydrogen and TPP ion activity. Tips consist of 2 mm diameter plastic tubes sealed at one end with an ion-sensitive membrane. After filling the ion selective electrodes with electrolyte solution, you can insert the tube into the holder and connect it to a pH meter. Tips and holders are interchangeable, so one tip may be replaced with another sensitive to a different ion. Replacing a tip takes less than a minute. Electrode tips normally last several months, when stored properly in saline solution. When replacement is necessary, only the tip needs be replaced.
Kwik-Tip electrodes are available separately and as kits. A separate reference electrode, such as WPI’s Dri-Ref™, is also required.
