LabInGlass products

Due to its expertise, and by adapting to a multitude of parameters, Klearia offers microfluidic chips tailored to your requirements. 


Custom made chip

1. Choice of substrate characteristics


Glass chip advantages


Glass is a material of choice for microfluidics because of its advantageous properties:


  • Chemical inertia (except hydrofluoric acid derivatives)

  • Optical transparency

  • Low autofluorescence

  • Strength (high Young’s modulus allowing to inject several bars)

  • Adapted to prototyping and mass production

  • Low contamination: non-porous material

  • Stable in time: recurrent handling and easy cleaning


Material substrate

Depending on application (optical transparency, operating temperature, cost …), we can provide a microfluidic chips in various types of glass:

  • Fused Silica

  • D263

  • Borofloat 33


Chip dimensions


Manufacturing process is suitable for 4" wafers.


Final chips can have all possible dimensions as long as it fits on 4" wafer (10cm diameter):


  • Up to 7cm x 7cm for square chip

  • Up to 8.5cm x 4cm for rectangular chip


For the same manufacturing, possible to add as many chips as possible on a 4" wafer.


Final chip thickness is the addition of the structured substrate thickness and the cover substrate; several thicknesses are available for these substrates ranging from 300μm up to 2mm.


2. Design and conception

If numerical file available, preferably please provide the formats .DXF, .GDS or .GDS2.


Channel design


According to the request, we can draw right angles, well-defined angles or curvatures:


Example of lines draws for mask design



  • Customer support to design your mask corresponding to needs.

  • Software for converting images to a numerical file.

  • To match the limitation of the manufacturing process, the smallest dimension on the mask is set at 10μm.

  • Multi-level etching

  • According to the customer's needs, we propose to make as many etching levels as necessary.

  • For each level, a lithography mask will be designed separately.

Sensors chips


Klearia overcomes a major technological limitation by bonding at a low temperature between 100°C and 300°C. This process (≤300°C) allows to integrate more materials for embedded technologies. 


With our technology, we are capable, besides, Pt, Au and Cu, to integrate termodegradable materials like carbon, nanostructured gold, etc.

Integrated sensor LabInGlass

Thin film integration allows the manufacture of sensors chips with devices of one microfluidic channel allowing multiplexing detection. Each microfluidic channel is fitted with a set of 3 electrodes (working electrode WE, counter electrode CE and reference electrode RE).
