It can be accommodate 6 paper strips horizontally .Buffer can be saturated very fast in this mechanism. A recessed safety interlock switch breaks the current of both electrodes while the lid of mechanism is uplifted. Both electrode section have capacity of 550ml and each are provided with transverse baffles to minimize. Diffusion of buffer which is in contact with the ends of paper strips. Polarity of the electrode is indicate by two pilot lamps provided on the front panel. The complete mechanism is fitted with leveling screws of facilitate leveling .The elementary unit consists of anode and cathode reservoir with platinum electrodes, special glass lid and power cord.
