Product Description

The Copper Purity Test Apparatus is a complete analytical setup designed to determine the purity of Electrolytic Tough Pitch (ETP) copper with accuracy up to 99.9%. Engineered for cable, conductor, and electrical manufacturing industries, this apparatus follows IS:191 (Part V & VI) 1980 and IS:440-1964 standards, ensuring reliable and repeatable electrolytic purity testing.

Working Principle

The apparatus operates on an electrolytic deposition method where the copper sample is dissolved in a sulphuric acid–nitric acid solution. Copper is then deposited electrolytically on the platinum-iridium electrodes.
For copper purity below 99.5%, impurities are removed using ferric hydroxide before electro-deposition, ensuring highly accurate purity results.

Main Unit Features

The main control unit includes digital ampere and volt indicators, a multi-turn current regulator for precise current setting, and a durable powder-coated body. It provides stable, controlled current essential for accurate copper deposition.

Magnetic Stirrer with Hot Plate

The stainless steel magnetic stirrer houses a DC motor for uniform mixing and a hot plate to maintain ideal temperature conditions. Adjustable motor speed and controlled heating allow optimized chemical reaction and uniform deposition.

High-Quality Electrodes

The platinum-iridium cathode and anode are manufactured to meet IS specifications, ensuring long service life, consistent results, and superior electro-chemical stability.
