Product Features

  • Special Thermohead™ provides extremely low thermal drift (less than 10 nm/°C) ensuring high stability of the tip-sample system. This allows long-term measurements to be done in pre-defined point on the specimen surface.
  • Temperature control with sample temperature alteration is possible in the range of -30°C (Peltier element) to 200°C with the high temperature maintenance accuracy. It allows the observation of the structural changes on the specimen surface, such as crystallization, melting, growth processes, etc. with precise experiment conditions control.
  • Different liquid cells are available: hermetic chemically stable liquid flow cell with a possibility of the temperature control at elevated temperatures; closed liquid flow temperature controlled cell for operating with Petri dishes; replaceable heater.
