The LRN15M mini roll to roll (R2R) coater from Grafisk Maskinfabrik is an easy-to-use entry platform for multipurpose OPV/other coatings.

Developed in cooperation with the Danish Technical University to mimic processing in a roll-to-roll machine without the high material consumption and upstart time requirements. It is a hands-on, precision instrument for slot-die coating any solution-processable material onto flexible substrates.
