Microfluidics

We make custom made nickel shims to produce microfluidic and Lab-on-a-chip (LOC) systems by hot-embossing or injection molding. We make the shims according to customer specifications regarding thickness, size, format, pattern and pattern depths. Moreover, the shims can be cut into any size and format within 140 mm diameter by laser cutting.

  • Lateral pattern dimensions from 50 nm to 1 mm
  • Pattern depths between 50 nm to 30 µm
  • Multiple pattern depths possible, 4 levels demonstrated

We also offer prototyping services by injection and lid bonding. Please contact us for more information.
