Info sui prodotti "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.

Soluzione standard di potassio -Low

Gli standard ISE basso e alto vengono utilizzati per calibrare i nostri elettrodi selettivi agli ioni di potassio. Bassa concentrazione: questa soluzione da 500 mL ha una concentrazione di 10 mg/L ed è utilizzabile con ISE di potassio. Alta concentrazione: questa soluzione da 500 mL ha una concentrazione di 1000 mg/L ed è utilizzabile con ISE di potassio.

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.

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.

Go Direct® Elettrodo ione-selettivo di potassio

Utilizzare l'elettrodo Go Direct Potassium Ion-Selective per misurare i livelli di ioni di potassio in modalità wireless. Il versatile connettore BNC consente agli studenti di sostituire facilmente l'elettrodo quando scade o si danneggia. Basta sostituire l'elettrodo e non l'intero sensore, riducendo così i costi complessivi dell'attrezzatura. Il Go Direct Potassium Ion-Selective Electrode ha uno stile combinato, non ricaricabile, pieno di gel. Come tutte le altre membrane in PVC ISE, la membrana su ISE ha un'aspettativa di vita limitata. Tuttavia, il modulo sostituibile di ISE consente di scartare semplicemente il modulo di membrana usato e sostituirlo con uno nuovo.
