MBRAUN Sublimation
Tool for Refining Organic Materials
The MBRAUN vacuum sublimation
unit is an integrated system for refining organic materials
to be used in OLED / PLED, organic lighting, organic
photovoltaic and organic electronics applications. The
sublimation and the subsequent crystallization process
significantly improves the electronic properties of
the materials and their lifetimes.
Getting rid of residual of synthesis, catalysts, precursors,
fragments, solvents, water and oxygen the performance
of the device is improved because of higher quantum
efficiency, higher charge carrier mobility and lower
degradation in time.
With a fractionated vaporization followed by a precisely
controlled re-crystallization a perfect starting material
is generated. MBRAUN offers
manually and automatically operated systems with a capacity
between 5-1000 g of raw material. The systems are integrated
in a MBRAUN glove box to
avoid contamination of the refined materials with oxygen
and moisture. In combination with an evaporation system
integrated in the same glove box line the loading of
the organic evaporation sources is very convenient and
without any contamination problems.
