Basic laboratory equipment for the pastes and inks production. Weighing, deagglomerating, homogenizing and grinding.

  • Mortar grinder enables dry and wet grinding of soft, medium-hard, hard materials, also in the form of pastes, with a hardness of up to 9 on the Mohs scale.
  • Three Roll Mill is crucially important in the research, development and production of especially nanocarbon-based materials, but also others. They enable high-precision dispersion down to the nano range as well as the homogenization and improvement of the rheology of printing pastes


  • The balances indicate the measured result to 4 decimal places.
  • Ultrasonic baths of capacities of 1,8-2,8l and 6-10l.
  • Ultrasonic reactor: 750 Watt, from 250 microliters to 1 liter; 10 hour process timer.
  • Kakuhunter Planetary Mixer SK-350TII CE: 90 different revolution-rotation speed patterns are available by varying the ratio of revolution and rotation, speed: 0 rpm – 1,430 rpm.
  • Three roll mill EXAKT 80E: maximum product fineness up to < 1µm, depending on the product; output between 0.02 and 20 l per hour- IKA evaporator RV 10: Speed range 5 – 280 rpm; Reversible direction of rotation; Heating temperature range: room temperature – 180 °C.
  • Hotplate stirrers: Rotation speed range 100 – 1,400 rpm; Hotplate temperature 20 – 300 °C.
  • Mortar grinder: Batch quantities ~10 – 190 ml with a maximum grain size of 8 mm.
