    5 introduction barnstead electrically heated water stills are available in four sizes; 1, 2, 5 and 10 gallons per hour of distilled water. The distilled water produced by the stills contains not more than 1.0 ppm total solids, with a ph value of 5.4 to 7.2 and an electrical resistance of not less th...

    6 condenser still condensers are the horizontal type, slightly inclined and atmospherically vented for final elimination of volatiles. The condensers are fab- ricated of copper and brass and are finished in polished nickel. All surfaces that contact the vapor and distillate are coated with pure tin ...

    7 when the water level is at a safe level in the still evaporator (the water level is above the immer- sion type heaters and makes contact with the probe), the circuit across probe terminals 1 and 2 at the terminal board (tb1) is completed. The completion of this circuit, after a two-second delay to...

    14 deconcentrator adjustment the function of the deconcentrator is to maintain a minimum concentration of dissolved impurities in the evaporator, thus reducing scale formation and tendency to foam to a minimum. The decon- centrator is adjusted as follows: 1. Permanent hard water or softened water (s...

    21 the still consists primarily of a boiler or evapora- tor which holds the water during the evaporation process; electric heating elements of the immersion type inserted in the evaporator to boil the water; and a condenser which condenses the steam from the boiler to form the distillate. The water ...
