Kristall 650 is an electrolytic polishing and etching tool which is easy to transport and operates independently of the mains. It is ideal for usage outside the lab.

Kristall 680 is a fully automatic electrolytic polisher and etcher with intuitive touchscreen operation. Polishing and etching unit and control unit are separated; Kristall 680 may be operated in a lab fume cabinet. A scan function displays the current voltage curve of a material and quickly provides polishing results without structural changes. The electrolyte vessel may be exchanged and is stored with a lid.

The KRISTALL 680 is a fully automatic electrolytic polisher and etcher with intuitive touch-screen operation. The polishing and etching unit is separated from the control unit so that the Kristall 680 may also be used in a lab fume cabinet.

A scan function displays the current voltage curve of a material and provides polishing results quickly without structural changes. Handling of the polishing and etching unit was facilitated significantly by the interchangeable 1 Ltr. electrolytic tanks. Different electrolytes can be changed and easily stored with lid. The unit is cleaned with water by a washing program.

Key features

  • Automatic, electrolytic polishing & etching device
  • Touch-screen display with QATM-software control
  • Up to 200 programs with all parameters storable, protected per password
  • Current & voltage diagram in real time
  • Variable output voltage and process duration
