Potassium Ion-Selective Electrode

Informations sur le produit "Potassium Ion-Selective Electrode"

The Potassium Ion-Selective Electrode can be used to measure the concentration of potassium (K+) ions in aqueous solutions.

The Potassium Ion-Selective Electrode makes the measure of potassium ions portable. When used with a Vernier LabQuest 2, the Potassium ISE can be used to take readings in the field – at lakes or streams. This sensor is easier to set up and use than other methods of measuring potassium ion concentration in aqueous solutions. Because it is a stick-style sensor, its use is similar to using a conductivity probe or a pH sensor in a laboratory setting or in the field.

Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results. They are not recommended for middle school or elementary students.

Standard Potassium Solution - Low
Les étalons Low ISE sont utilisés pour étalonner nos électrodes sélectives aux ions de potassium. Faible concentration: Cette solution de 500 mL a une concentration de 10 mg/L et doit être utilisée avec l'ISE de potassium. Concentration élevée: Cette solution de 500 mL a une concentration de 1 000 mg/L et doit être utilisée avec l'ISE de potassium.

Electrode Support
The Vernier Electrode Support connects to all standard ring-stand posts to keep sensors firmly in place during an experiment. The Electrode Support is a great complement to the Vernier Stir Station, as well as a perfect holder for many sensors. It is built to connect to all standard ring-stand posts; its large-handled locking nut keeps your sensors firmly in place. The larger opening (13 mm in diameter) is perfect for our pH, ISE, Conductivity and ORP sensors. The smaller opening (5 mm) is designed to hold our Stainless Steel Temperature Probe or the Vernier Go!Temp. The clamp end makes connecting to ring stands easy, accommodating post diameters between ~0.5 and 1 cm. The grooves on the Electrode Support to hold the wire leads for electroplating or electrolysis experiments.

Nitrate Ion-Selective Electrode
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 Nitrate ISE to determine the concentration of the nitrate ion in a water sample. The 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. 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 middle school or elementary students.   NO3-BTA User manual

Calcium Ion-Selective Electrode
Data from the 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 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.

Go Direct® Électrode sélective pour ions potassium
Utilisez l'électrode sélective d'ions potassium Go Direct pour mesurer sans fil les niveaux d'ions potassium. Le connecteur BNC polyvalent permet aux étudiants de remplacer facilement l'électrode lorsqu'elle expire ou est endommagée. Vous n'avez qu'à remplacer l'électrode et non le capteur entier, ce qui réduit vos coûts d'équipement. L'électrode sélective pour ions potassium Go Direct est dotée d'une électrode de type combiné, non rechargeable et remplie de gel. Comme toutes les autres membranes ISE en PVC, la membrane de l'ISE a une durée de vie limitée. Cependant, le module remplaçable de l'ISE vous permet de vous débarrasser du module de membrane usagé et de le remplacer par un nouveau module.
