UniMill for TEM users

by Gergely Balogh

UniMill – Fully automated ion beam thinning system for TEM/XTEM sample preparation.

The UniMill model of Technoorg ion mills has been designed for extremely rapid preparation of high-quality TEM/XTEM samples with unsurpassed high thinning rate. The design of the instrument enables both rapid milling with the ultra-high-energy noble gas ion source and final polishing and cleaning with the patented low-energy ion gun.

  • Easy to use and automated operation
  • Widest energy range on the market (100 eV- 16 keV)
  • Load-lock system for fast sample exchange
  • LN2 or Peltier cooling option
  • Online monitoring and support

“Dual function ”

The wide energy range of the ion sources allows extremely high milling rate and gentle cleaning function with the same instrument.

Easy to use and automated operation

The UniMill is provided with full computer control utilizing an easy-to-use graphical interface. All milling parameters can be stored or pre-programmed in arbitrary number of steps. This fully automated feature of the UniMill allows to produce high-quality samples with minimum user intervention.

Sample cooling

To cover all possible needs UniMill offers two different cooling options:

The Liquid Nitrogen cooling reduces excessive sample heating during the ion bombardment. Thus, heat-sensitive materials can be prepared without destabilization of internal structures.

Peltier cooling is a comfortable protection against overheating and to keep the sample on room temperature.

Fast and motorized sample exchange

The load-lock and the motorized sample holder driving system provides fast and easy sample exchange with the least possible user interaction. The load-lock protects the vacuum level in the working chamber to save significant time and energy for heavy users.

Online monitoring and support

The UniMill is supplied with a software extension for online technical support, which enables instant error detection and program elimination via the internet.
