Cole-Parmer® Replaceable Membrane Ion-Selective Electrodes

Don't throw it away—replace worn membranes quickly

Membrane replacement saves time and the expense of electrode replacement — ideal for continuous or frequent sample analysis. The durable outer epoxy body is ideal for field applications and the PVC membranes are color coded for easier identification. To sense a new ion, interchange membranes of the same type. Simply replace the worn membrane without removing any other component of the electrode. The replaceable membrane is not part of the liquid junction, so adding the new membrane will not affect it. The reference electrolyte won’t leak during membrane replacement. These double-junction combination electrodes require no external reference. Electrodes are refillable with an outer silver-free reference fill.

Electrodes with PVC Membranes include one sensing module (in place), reference fill solution, internal fill solution, BNC connector with 3-ft cable, and instruction manual.

Electrodes with Solid-State Membranes include one sensing module (in place), polishing strips, reference fill solution, BNC connector with 3-ft cable, and instruction manual.
