The METALTHIN Twin-Jet Electropolisher was originally developed for producing high quality thin foils from radioactive materials. It is robust, compact, economical and easy to use. The electrolyte tank, sample holder, thinning cell and tank base stand are machined from solid PVC to provide maximum resistance to corrosive electrolytes. The Cell parts are held together by stainless steel screws so that the Cell is easy to disassemble.
The METALTHIN Mk4 system incorporates the accumulated experience of many years of use in Universities, Industrial and Nuclear Research Centers and comprises Thinning Cell and Control/Power Supply plus the optional Unipump and Dewar Flask.
Features:
- A stainless steel cooling coil is an integral part of the thinning cell. It has three turns and the resulting increased surface area improves the cooling speed and temperature control.
- The photo-cell detector and light source plug into connectors at the ends of their respective leads.
- The photo-cell detector and light source are contained in stainless steel housings that push-fit into the thinning cell.
- A base stand that holds the thinning cell securely and collects drips of electrolyte.
- An additional electrolyte tank is provided for washing/cleaning the thinning cell.
- The impeller screws onto the pump shaft.
- Push-on electrical connections facilitate setting up and operation.
- The base of the pump motor is protected from the electrolyte by a stainless steel plate.
- New Feature: Changes in the design of the specimen holder have improved the holding of thin discs at low temperatures.
Thinning Cell - The thinning cell is contained in an electrolyte tank that press fits into a solid PVC base stand especially designed to collect drips of electrolyte. An additional electrolyte tank is provided for washing the cell after use.
Power Supply - Completely separate from the thinning cell and cannot be operated until a key is inserted into the main switch and turned.
New Features - Thinning current control: During the thinning process, small changes in electrical resistivity are caused by variations in the temperature of the electrolyte and by the thinning process itself. the CONTROL CURRENT facility automatically maintains the current that is initially set by the operator. This avoids the need to constantly monitor and adjust the setting.
The range of cell resistances to which automatic control of the thinning current can be applied are those that apply to the majority of electrolytes. If the conditions are outside the range of automatic control, the control current switch will flash to shwo that manual control is required.
- The external case has greatly increased strength and resistance to corrosive electrolytes.
- The electrical and instrumentation leads plug into the rear of the power supply to protect the connections from accidental contact with the electrolyte.
- The push switches are arranged in a single line on the front of the power supply.
- The push switches are fitted with flexible transparent covers to protect them from accidental contact with the electrolyte.
- The voltage and thinning current are displayed digitally.
