Daniell Cell Demonstration Apparatus

Product Code : SCL-EAE-11319

The Daniell Cell Demonstration Apparatus is a primary voltaic cell used to demonstrate how a spontaneous redox reaction converts chemical energy into electrical energy. Its separated copper and zinc electrode systems allow students to investigate electrode polarity, electron flow, cell EMF and electrochemical energy conversion.

Product Description

The apparatus uses a heavy-gauge copper outer vessel as the positive electrode. A porous pot separates the internal zinc-electrode compartment from the surrounding copper-electrode system while permitting ionic conduction between the electrolytes. A perforated internal shelf is provided for copper sulphate crystals.

A zinc-amalgam rod fitted with a wooden supporting cap acts as the negative electrode. The zinc rod and copper vessel each include a 4 mm terminal socket for connection to suitable laboratory leads and measuring instruments. When correctly prepared, the working cell produces an electromotive force of approximately 1.1 V.

Key Features

• Working primary voltaic cell: Demonstrates direct conversion of chemical energy into electrical energy.
• Approximate 1.1 V EMF: Provides a measurable low-voltage output under suitable experimental conditions.
• Copper positive electrode: The heavy-gauge outer vessel serves as the cell’s positive terminal.
• Zinc negative electrode: A zinc-amalgam rod forms the negative electrode system.
• Porous-pot separation: Keeps the electrode solutions separated while supporting ionic conduction.
• Crystal shelf: An internal perforated shelf accommodates copper sulphate crystals.
• 4 mm terminal sockets: Supports connection to standard compatible laboratory leads.
