  • Sample should be well polished and havingsmooth surface.
  • Maximum of six samples will be accepted at a time for room temperature.
  • Maximum of two samples will be accepted at a time with temperature measurement.
  • Maximum sample dimension should be diameter of 3 cm and thickness 0.3 cm for Low frequency, and diameter 1 cm and 0.2 cm thickness for RF.
  • After applying silver paste (Conducting coating) to samples it should be heated at 50oC at least for one hour.
  • User has to bring liquid nitrogen.
  • Only one registration will be accepted at a time.
