Vernier Calcium Ion-Selective Electrode

Note: Prices do NOT include GST or freight

Vernier's Calcium Ion-Selective Electrode (ISE) can be used to measure the concentration of Calcium (Ca2+) in aqueous samples.

Data from the Vernier Calcium ISE can give a good indication of hardness of water (as Ca2+). The concentration of calcium is also used as an endpoint indicator in EDTA-Ca/Mg hardwater titrations.

The Vernier Calcium ISE has a combination-style, non-refillable, gel-filled electrode. Like all other PVC ISE membranes, the membrane on the ISE has a limited life expectancy. However, the replaceable module of ISE allows you to simply discard the used membrane module and replace it with a new one.

As this product has a finite shelf life we import it as required, please allow 4 to 6 weeks for delivery from the date of your order.

Note: We recommend that you do not purchase ISE replacement modules too far in advance of their expected time of use as degradation occurs while they are stored on the shelf.

Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results. They are not recommended for junior high school students.

Compatibility Requirements:
The Vernier Calcium Ion-Selective Electrode may require a compatible interface and software.
