Storing perchloric acid or solution
CAUTION
Do not produce anhydrous perchloric acid, either from its salts or from aqueous
solutions, e.g. by heating with high boiling acids or dehydrating agents such as
sulfuric acid or phosphorous pentoxide. In addition to spontaneous explosion, the
anhydrous acid explodes instantaneously on contact with oxidizable organic
materials.
CAUTION
Limit the use or storage of perchloric acid to quantities less than 500 g per fume hood.
3.
Never let perchloric acid crystallize on bottle necks, caps or anywhere else.
4.
Store the chemical in a secure, cool, and well-ventilated area with a metal, glass or ceramic spill
catch pan.
5.
Store the chemical away from other chemicals or combustible or organic materials.
6.
Never let solutions dry out.

Device description
MoviPol-5 is used for on-site materialographic preparation and enables examination and quality
inspection of metallographic materials.
Electrolytical polishing/etching can be performed on most metallic material surfaces. It is an
electrochemical process, which can be performed on electrically conductive materials by applying an
electrolyte and electricity to the test area.
Before starting the process, the user must wear protective goggles and gloves.
During the process, a high, local current, when applied to an area of the material covered by the
electrolyte, will have a polishing/etching effect on the targeted surface. This makes the surface
suitable for further materialographic analysis. The process is non-destructive and does not introduce
deformation to the micro-structure of the workpiece.
MoviPol-5 is portable. It is packed in a case, which is suitable for transport by one person. The
equipment has a replaceable, rechargeable battery. Electrolytes are contained in an electrolyte
cartridge, which is filled/emptied by the operator.
The process starts with the operator identifying a relevant surface area and the type of material that
needs inspection. A suitable method, accessory and electrolyte are identified. Before operation the
operator places the equipment on a plane surface or, if carrying, keeps it level.
