THE BUILT IN LAMP PROVIDES UNIFORM AND SHADOWLESS ILLUMINATION OF SAMPLE TUBE WHICH ARE VIEWED THROUGH THE MAGNIFYING LENS AGAINST EITHER A DARK OR BRIGHT GROUND SELECTED BY ROTATING A KNOW TO THE REAR OF THE APPARATUS .

A BUILT IN A ROTARY THERMOSTAT GIVES ACCURATE ADJUSTMENT OF THE RATE OF INCREASE OF TEMPERATURE AS MELTING POINT IS APPROACHED. BOTH THE HEATERS ARE KEPT ‘ON’ IN THE ‘LOW’ AS WELL AS ‘HIGH’ POSITION OF THE TOGGLE SWITCH, THUS ENSURING UNIFORM HEATING FROM BOTH SIDES OF THE BLOCK. A SECOND TOGGLE SWITCH ON THE RIGHT SIDE CONNECTS THE LAMP AND POWER INPUT TO THE APPARATUS.
