  • Superior, stable PVC membrane
  • Fast Response
  • 2mm diameter tips (Package of 3)
  • Interchangeable tip holder

Details

These highly stable electrodes accurately measure 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 with electrolyte solution, the user inserts the tube into the holder and connects 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 to be replaced.

Available as kits

Kwik-Tip electrodes are available separately and as kits. Each "KWIK" Elec­trode Holder kit includes a reusable holder and three removable tips. In addition to a 4-foot BNC cable and an electrolyte filling syringe. "TIP" Electrode Kits contain three electrode tips for a specific ion. A separate reference electrode, such as WPI's Dri-Ref™, is also required.
