Voltameter, Copper Manufacturer,Supplier and Exporter in India

Voltameter, Copper (Product Code: SLE/EM/27) is an electrolysis cell in which the charge passed is measured by the mass of copper deposited. Three copper plates hang from the bakelite cover of a plastic jar: the two outer plates act together as a double anode, while the inner plate is the cathode and lifts out easily for weighing. Physics and chemistry teachers use it for practicals on Faraday’s laws of electrolysis, making it one of the simpler electrochemistry instruments a school or college lab can own. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

To find the electrochemical equivalent of copper, clean and weigh the cathode, fill the jar with copper sulphate solution, and connect the anode and cathode posts to a DC supply through an ammeter, a rheostat and a key. Pass a steady current for a timed interval, then rinse, dry and reweigh the cathode: the gain in mass divided by the charge passed (current × time) gives the result. Because the cathode sits between the two anode plates, copper deposits on both of its faces, which helps give an even coating.

A regulated supply and a rheostat make it easier to hold the current constant during the run. Handle the cathode by its edges once it has been cleaned, dry it thoroughly before each weighing, and rinse all plates after use so that dried electrolyte does not build up on the cover. The same cell can also be used to show that the anode loses copper while the cathode gains it.

What you need to run a complete electrolysis practical:

• Cupric Sulphate (Copper Sulphate) — for preparing the electrolyte
• Digital Ammeter — records the current passed through the cell
• Rheostat — keeps the current steady during the timed run
• Precision Variable Power Supply — a regulated DC source for electrolysis
• Electrodes, Copper — separate copper electrodes for other electrolysis set-ups

Frequently Asked Questions

Which plate is the cathode?
The inner copper plate, which is fixed to its own binding post and can be removed easily for weighing. The two outer plates form the double anode.

Is the copper sulphate electrolyte included?
The listing covers the jar, cover and three plates only, so the electrolyte should be ordered or prepared separately — we can quote it with the voltameter.

What experiment is it mainly used for?
Determining the electrochemical equivalent of copper and verifying Faraday’s first law of electrolysis.

What current should be used?
A recommended current is not given in our current listing; contact us and we will advise before you plan the practical.

Why are there two anode plates?
Placing an anode on each side of the cathode lets copper deposit on both faces of the cathode.

How should the plates be looked after?
Rinse them after each use, dry them before storage, and clean the cathode before weighing so that only freshly deposited copper is measured.

Can you supply several voltameters for a practical batch?
Yes. We supply schools, colleges and distributors in India and international markets; send the quantity and delivery location for a quotation.
