Custom devices
Dolomite works with customers around the world to develop a variety of versatile, complex and cutting edge custom devices, available in exceptionally short lead times.
Our team of design engineers has many years of experience in modelling, designing and testing microfluidic devices for a range of applications including microreactors, DNA analysis, droplet generation and environmental analysis.
After selecting a suitable fabrication process, chip material, surface coatings, connection methods and pumping solutions, we can also help you with additional features, such as on-chip filters, mixers and flow resistors to optimize the performance of your custom device.

Dolomite's design expertise
- World leading thermal bonding process: low temperature minimizes thermal distortions.
- First class wet etching of microchannels: superior optical quality of channels with etch depths of nm to mm deep in glass and borosilicate.
- Grinding and polishing techniques: wide range of substrate thicknesses from as thin as 100μm to > 40mm thick.
- Multi-layer chips: multiple layers can be fused to create complex geometries.
- Excellent drilling, dicing and ultrasonic machining techniques: vertical sidewalls from as little as 100µm to more than 10mm in diameter.
- Novel interconnect technology: innovative dicing techniques ensure incredibly precise ‘edge connection’.
- Extremely accurate alignment
- Variety of deposited coatings: all chips can be sputtered with metals such as platinum, gold, copper and titanium to create a wide range of features, such as embedded RTDs, sensors, mirrors and electrodes.
- Unrivalled lead times allowing complex chips fabricated and delivered in as little as 4 weeks.
