• Produces high quality conductive TEM specimen of 3 mm diameter
• System consists of electrolyte tank, specimen holder, thinning cell and tank base
• Electrolyte is pumped from the tank using a motor driven impeller to impinge jets on the specimen from both sides
• DC Power supply of 0-200v, 0-2A and control electronics housed in separate cabinet delivers the potential to the electrodes
• A light source and photocell detector detects perforation to auto terminate the process
• Specially designed specimen holder to hold 3mm diameter specimen to ensure sturdy rim of the specimen (Customized holders to hold smaller specimen are available)
• Electrolyte is cooled using an immersed cooling coil through which liquid nitrogen can be delivered from a modified dewar flask
• System can incorporate different types of electrolytes depending on the specimen material

Control Function: 

• Control of the electrolyte flow rate
• Control of the DC voltage to the electrodes
• Illumination of the disc and detection of perforation followed by automatic cessation of electrolyte flow and dc current

• Audible alarm to sound when perforation is detected
• Real time graphical display of current versus time at the time from process start
• Display of actual thinning time up to 999 seconds
• PLC with 7″ HMI to Enable the Operation
• Provision to store 50 recipes of various samples with their respective data such as material name, current, time, temperature, sensitivity, flow-rate for future reference

MDF-2.2L

• Cryogenic Modified Dewar Flask with liquid nitrogen transfer hose with flow control valves & pressure regulator to enable control of temperature in the thinning unit from room temperature to -50 °C within ± 2°C
