High Quality 2D Transfer Systems

HQ Graphene Systems BV designs, produces and sells transfer systems worldwide.



In the field of 2D materials research, the production of layered structures is gaining widespread attention. In these structures, the layers can be stacked in a wide variety of alignments and orientations, each configuration having its own (potentially) interesting physical or chemical properties. Our transfer systems are designed to accurately place a stamp (with for example hexagonal boron nitride, graphene, etc.) on a substrate, which can be moved relative to each other not only in the x-, y- and z-directions but also by tilting and rotation. This allows for the highest degree of freedom in the alignment of 2D crystal flakes when fabricating heterostructures and twisted layered structures.

The substrate is fixated with vacuum and can be temperature controlled between RT and 200 °C. The compact design allows for easy placement inside a glovebox, providing the option to work with air sensitive materials.

All systems are supplied with a high resolution microscope having long working distance objectives and allowing for bright field / dark field illumination at choice. For our manual systems, one can also choose for a pure bright field microscope. All microscopes are equipped with a correction collar objective optimizing vision through the glass plate bearing a stamp.

We offer fully motorized systems, manually operated systems, and partially motorized systems. We also provide modified transfer systems having different compositions or configurations of the mechanical platform, or, for instance, having equipment for nanowire manipulation.

All systems purchased from HQ Graphene Systems BV come with a 1 year warranty as well as remote support during weekdays by our engineers.

Fully motorized transfer system (HQ2D MOT)


Apart from loading the sample and mask, performing a transfer on this system is completely software controlled, making it ideal for use inside a glovebox to be able to work with highly sensitive materials. The dedicated HQ Graphene Transfer Stage program guides you through all steps in an intuitive manner, offering many useful features such as image saving, sample position storage and automatic focusing. All relevant actions and conditions are clearly monitored real time and can be adjusted with the keyboard or with the external controller for fast operation. This system is equipped with a dark field / bright field microscope supporting an extra camera for the wide angle field of view.

Manual transfer system (HQ2D MAN)


The manual system is destined for those who prefer a compact design and a hands-on operation. The mechanical platform is controlled with micromanipulators with differential screws for the fine, critical adjustments. Heater, cooler and vacuum are touchscreen controlled and integrated together with the LED adjustment knob in a compact HQ Graphene control box. The microscope is equipped with oculars and a camera with imaging software.

Customized transfer systems (HQ2D MOD)

Modified transfer systems

Product code Description
HQ2D MOT-N Fully motorized transfer system meant for 2D transfers and also equipped with an integrated orientable needle that can pick up, displace and reorient a nanowire. The needle is connected to the software commanded mask holder.
HQ2D MAN-N Manual transfer system meant for 2D transfers and also equipped with an integrated orientable needle that can pick up, displace en reorient a nanowire. The needle is connected to the manually operated mask holder.
HQ2D MOD MAN-2XYZ Manual transfer system with XY- and Z-stages for both the sample and the mask holder and an XY-stage for common displacement of sample and mask, so this system offers maximal freedom in the displacement of sample and/or mask. Can readily be equipped with stage motors.
HQ2D MOD MAN-2XYZ MROT As HQ2D MOD MAN-2XYZ, with a motorized sample rotation stage.
HQ2D MOD MAN-BF Standard manual transfer system with a pure bright field microscope without dark field illumination option.
