Examples
Some of the bespoke solutions that we developed recently:
- Quartz capillary electrophoresis chip: 160mm x 40mm.
- 1ml Chip: 3 layers etched to 300µm deep per layer.
- Nozzle spray device with integrated platinum electrodes.
- Silica chips: Etched on both layers, aligned < 5µm, one layer polished to 150µm, designed and delivered in just 4 weeks.
- Gas chromatography chip (4” x 4” footprint): Etched on both layers, one layer polished to 250µm, with over 7 metres of channel network.
- Cell sorting chip: Designed and fabricated with over 2 million integrated electrode features.
- Polymer chips: Cost-effective, functional prototype developed in tens for healthcare application.
Dolomite's expertise
|
