TWIN JET ELECTROPOLISHER TEM-JP250-1

• Used for producing high quality conductive TEM specimen of 3 mm diameter of maximum thickness 150 micron
• Additionally, holder to hold 1.5 mm diameter sample is optionally available
• System consists of electrolyte tank, specimen holder, thinning cell and tank base
• The thinning cell is contained in an electrolyte tank that press fits into a base stand specially designed to collect drips of electrolyte
• An additional electrolyte tank is provided for washing the cell after use
• Electrolyte is pumped from the tank using a 12V DC motor driven impeller to impinge jets on the specimen from both sides
• A light source and photocell detector detects perforation in the specimen to terminate the electropolishing process
• Specimen is held in a specially designed holder to ensure sturdy rim of the specimen for ease of handling
• The electrolyte can be cooled using an immersed cooling coil through which liquid nitrogen can be delivered from a modified Dewar flask, MDF-2.2L, temperature of which is displayed on the touchscreen HMI
• System can incorporate different types of electrolytes depending on the specimen material
• Hazards associated with the use of inflammable/corrosive electrolytes and their disposals are reduced by the low volume of electrolyte
• DC power supply of 0-200 V, 0-150 mA and control electronics housed in separate cabinet delivers the potential to the electrodes

• Control of the electrolyte flow rate
• Control of the DC voltage to the electrodes
• Detection of perforation followed by automatic cessation of electrolyte flow and DC current
• Audio-visual alarm as soon as perforation is detected
• Real time graphical display of current versus time from process start
• Display of actual thinning time up to 999 seconds
• PLC with 7" inch touch screen HMI
• Provision to store 500 recipes of various samples with their respective data such as material name, time, temperature, sensitivity, flow rate for future reference

• Perchloric Acid
• Nitric Acid
• Pure Lab Grade Methanol
• Ethanol
