COPPER PURITY TEST APPARATUS-BASIC

SCOPE
APPARATUS CONFINED TO OBTAIN PURITY OF COPPER UPTO 99.9 % BY ELECTROLYTIC METHOD. THIS METHOD REQUIRES A 0.001 MILI-GRAM WEIGHING SCALE (OPTIONAL), IN ORDER TO SEEK THE MOST PRECISE RESULTS, AS WELL AS NECESSARY TESTING PRECAUTIONS SHOULD BE TAKEN.

PRINCIPLE
THE SAMPLE COPPER IS DISSOLVE IN SULPHURIC- ACID NITRIC ACID MIXTURE AND COPPER DEPOSITED ELECTROLYTICALLY FROM THE SOLUTION. IN CASE OF COPPER, HAVING A PURITY OF LESS THAN 99.9 PERCENT, IMPURITIES ARE REMOVED BY FERRIC HYDROXIDE AND THEN COPPER DEPOSITED ELECTROLYTICALLY

APPARATUS COMPRISES OF:-
MAIN UNIT
COMPRISES OF DIGITAL INDICATOR OF AMPERE METER. ONE ON/OFF TOGGLE SWITCH MAINS INDICATOR LAMP, DIGITAL TEMP. CONTROLLER CUM INDICATOR, DIGITAL TIMER, EMERGENCY STOP AND MULTI TURN REGULATOR FOR THE AMPERE SETTING. OVERALL BODY IS POWDER COATED.
MAGNETIC STIRRER
CUBICAL BOX CONTAINS THE DC MOTOR AND HOT PLATE FOR THE BEAKER CONTAINING SOLUTION OF COPPER. SPEED OF DC MOTOR CONTROLLED BY REGULATOR. HEATING OF HOT PLATE CONTROLLED BY ENERGY REGULATOR. ONE MS ROD IS INSTALLED VERTICALLY AT THE REAR SIDE TO SUPPORT THE ACRYLIC BAR BEARING ELECTRODES. OVERALL BODY IS MADE OF MILD STEEL WITH HEAT RESISTANT PAINT.
LOAD CAPACITY 1 KW, 220 VOLTS AC.
ELECTRODES
CATHODE AND ANODE ARE MADE OF TITANIUM IRREDIUM ALLOY AND PLATED WITH PLATINUM COATING WITH SOME TREATMENT CONFIRMS THE GUIDELINES OF SAID SPECIFICATION.
