High Aspect Ratio Glass Microfluidics

Low-cost, deep micro-features open up the third dimension for everyone in micro-fluidics

Glass is a substrate material which is used regularly for microfluidic applications. The most important reasons to use glass in microfluidics are its outstanding optical properties and chemical inertness. At the same time, glass has a limited range of application due to technical and economic constraints. LIDE overcomes these limitations by providing cost-effective solution to make deep micro-features in glass which for example enables multi-layer microfluidic chips.

 Benefits of LIDE-processed glass for microfluidic application


LIDE as an enabling technology makes previously inconceivable designs such as glass filter, 2.5D microfluidics and glass-based orifice plates possible.
High precision microfeatures in glass

With LIDE, microfeatures of single micron accuracy can be made in glass reliably and cost-effectively.

Deep microfeatures

Aspect ratios of 1:10 can regularly be achieved and aspect ratios of up to 1:50 are possible when using the right glass. Contact us.

Smooth surface

LIDE-processed glass keeps its initially smooth and optically transparent surface. The LIDE-processed glass channels have a roughness of Ra<0.8µm.

Freedom of design

LIDE makes the cheap and easy generation of microfluidic feedthrough through glass possible, giving designers the opportunity to design complex microfluidics networks by making use of both sides of a glass substrate.

Easy surface functionalization


LIDE-processed glass can easily be functionalized by standard surface treatments.
