For the preparation of nano-electromechanical structures as well as for the preparation of biological specimens, we operate a critical point dryer that prevents surface tension damage in nanostructures when removing them from etching or sample preparation solutions. Critical point drying is also a very common technique for the preparation of cell and bacteria samples before imaging with an electron microscope.

  • Prepare biological specimens for e.g. microscopy
  • Protect 3D-printed structures from surface tension damage in post-lithography processing
