VERNIER NITRATE ION-SELECTIVE ELECTRODE
Vernier's Nitrate Ion-Selective Electrode (ISE) can be used to measure the concentration of Nitrate (NO3-) in aqueous samples.
Nitrate concentration, which can be increased by acidic rainfall, fertilizer runoff from fields and plant or animal decay or waste, is an important parameter in nearly all water quality studies. Use the Vernier Nitrate ISE to determine the concentration of the nitrate ion in a water sample.
The Vernier Nitrate 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, allow 4 to 6 weeks for delivery from the date of your order.
Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for junior high school students.
