Inkjet printing

Inkjet printing is a flexible and versatile technique for applying minute amounts of material in a specific position on a substrate. The inkjet printing finds e.g. in the field of flexible electronic components by printing conductive materials on polymer substrates. Another field of application is material screening, whereby films of different composition are printed and subsequently examined spectroscopically.



The Microdrop Professional Inkjet Printer is used to formulate and position tiny drops of liquid on different planar substrates. The few picoliter drops contain biological components, e.g. Proteins, antibodies or cells, which can be deposited on the substrates in user-defined structures. The printer is equipped with different, partially heatable printheads with nozzle diameters between 30 μm to 100 μm and has a high-precision XY table.
