Big Drops, Small Drops, …
Initially the process starts with a more or less thin layer of liquid. This can be a photo resist for NIL as well as a protein solution for contact printing (Stamp inking). Optionally diverse liquid handling methods are available on the µCP4.1:
- Displacement pipet tips as you use it in your daily work flow
- Piezoelectric GeSiM dispensers for managing smallest volumes
- Piezoelectric valves (Third party) for making smallest drops of high-viscous media
Your application determines what works best. Please contact us for specific information.
Automated Resist Hardening
The µContactPrinter 4.1 can be accomplished by UV lamps of different intensity. One application is the curing of 3D resist structures immediately after nanoimprint lithography. The UV light applies directly through the optical transparent stamp.
All you need to adapt the instrument to your applications:
- Pneumatic extruders using disposable cartridge dispensers (As on the BioScaffold printer BS3.1). Heaters for the extruder is available too.
- Powder pipet for taking up and dispensing µg amounts
- Fluidic “flow-through” stamps for applying grains or bead during the microcontact printing process.
Entry-level Microcontact Printer
The handheld module fits on regular microscope stages. It is limited to a single stamp but uses the same stamping technique than µContactPrinter 4.1. UV-lamps for resist curing are optionally available.
