Calcium Ion-Selective Electrode

Informations sur le produit "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. 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.

Accessory Items

pH Buffer Capsules Kit
The pH Buffer Capsules Kit is a convenient set of three vials containing capsules to make pH 4, pH 7, and pH 10 buffer standards for calibrating pH sensors. Included with the set is one vial of Hydrion Color Key Buffer Preservative. Each vial contains 10 capsules, each of which produces 100 mL of solution when mixed with DI water. Add three drops of the buffer preservative to 100 mL of your buffer solution to prolong the shelf life. Hydrion Color Key Buffer Preservative is a combination mold inhibitor and universal indicator for color coding the buffer solutions: orange for pH 4, green for pH 7, and blue for pH 10. What’s included with the pH Buffer Capsule Kit: (10) pH 4 – Orange (10) pH 7 – Green (10) pH 10 – Blue Color Key Buffer Preservative Solution preparation instructions Safety Data Sheets

Water Quality with Vernier
Water Quality with Vernier has 18 water quality tests, including pH, total dissolved solids, dissolved oxygen, BOD, flow rate, turbidity, nitrates, and phosphates. All nine tests in the Water Quality Index (WQI) are supported. A comprehensive introduction is included for each test, providing important background information for the students. The printed version includes access to the electronic edition online.

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.

ISE Calcium Replacement Module
This module replaces the electrode membrane. Simply unscrew the old one and screw on the new one. The membrane of an Ammonium ISE electrode has a limited life span of one to two years, regardless of frequency of use. Do not order it until you need it, as it will age even when not in use.

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. User manual

Ammonium Ion-Selective Electrode
Use the Ammonium ISE to measure levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels if sample solutions are acidified to convert NH3 to NH4+. The Ammonium 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.

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.

Go Direct® Calcium Ion-Selective Electrode
Les données obtenues à l'aide de l'électrode sélective pour ions calcium Go Direct sans fil peuvent donner une bonne indication de la dureté de l'eau (sous forme de Ca2+). La concentration de calcium est aussi utilisée comme paramètre dans les titrages EDTA-Ca/Mg d'eau dure. 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 d'ions de calcium 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. Batterie rechargeable — Prêt lorsque vous êtes La batterie rechargeable robuste offre une longue autonomie et assure un fonctionnement toujours prêt lors de l'utilisation du capteur sans fil. Surveillez la durée de vie de la batterie directement à partir de notre application Vernier Graphical Analysis® primée, ainsi que de LabQuest® 3. Si la batterie est épuisée, il suffit de connecter le capteur au câble de charge et de continuer à collecter, sans interruption ni inconvénient pour vous ou vos élèves. Sans fil ou filaire — La flexibilité du choix Nos capteurs Go Direct se connectent directement à votre appareil mobile, Chromebook™ ou à votre ordinateur à l'aide de notre application Vernier Graphical Analysis®. Les capteurs Go Direct peuvent être utilisés par câble via USB ou sans fil via la technologie sans fil Bluetooth®, ce qui vous permet de choisir la solution qui convient le mieux à votre classe ou à votre laboratoire. Remarque: Nous vous recommandons de ne pas acheter les modules de remplacement ISE trop longtemps avant leur date d'utilisation prévue, car ils se détériorent pendant qu'ils sont entreposés sur les étagères.Important: Les électrodes sélectives d'ions requièrent une bonne technique chimique et un étalonnage minutieux pour obtenir des résultats précis; elles ne sont pas recommandées pour les élèves du collège ou du primaire.
