Applications
- Detection of ions in vivo or in vitro for biological applications
These highly stable electrodes accurately measure calcium, potassium, hydrogen and TPP (Tetraphenylphosphonium) ion activity. Tips consist of 2 mm diameter plastic tubes sealed at one end with an ion-sensitive membrane. After filling 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. 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.
If your pH meter requires a US Standard connector, you will also need Part 3508 (BNC-to-US pH Standard adapter).
