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.
