Filling and Emptying of Electrolyte

The volume corresponding to 1 liter is marked on the inside of the
electrolyte container. There must be at least 0.7 liter in the reservoir, but it is
recommended to use 1 liter.
If there is too little fluid, the pump may suck air into the liquid stream,
thereby disturbing the polishing. On the other hand, there is no point in
using more than one liter of fluid.
Prepare 1 liter electrolyte according to the prescribed regulations for the

electrolyte.
 Place the base plate with motor, cooling coil etc. on the electrolyte
reservoir which is not being used.
 Pour the prepared electrolyte into the reservoir (insulated/uninsulated),
which is to be used during the polishing processes.
Move the base plate back to the reservoir filled with electrolyte.

 Move the base plate from the reservoir filled with electrolyte to the
reservoir which is not being used. This might be filled with water so that
the first cleaning with water can start.
 If the electrolyte is to be re-used, it is poured back into its original
packaging or into another resistant packaging which is duly marked.
Funnel, gloves, ventilation as well as all other prescribed equipment
must be used during emptying.
 If the electrolyte is not to be used again, it should be filled into a
container suitable for disposal procedures. Please observe the local
regulations and instructions for disposal.
Clean the polishing unit by pumping water through the polishing cell

instead of electrolyte. Make three to four successive flushings by
changing from one reservoir to another. Between the changes fresh
water is poured into the reservoirs.
 After the final flushing, specimen holder and jet holders are taken out
and left to dry. The reservoirs and the polishing unit should be dried
with a damp cloth.
2.6.4. Cooling of Electrolyte
For two main reasons it is necessary to cool the electrolyte during use, i.e.:
 In most cases the best polishing results are obtained if the electrolyte is
cooled down (See section OPERATION, Electrolytes).
 For safety reasons; because of the fire hazard, evaporation of alcohol
etc. it is necessary to cool the electrolyte to a temperature below its
flash point.
With Tenupol-3 it is possible to cool the electrolyte by using either the built-
in cooling coil or by immersing the uninsulated reservoir in an ice bath.
