LSPone for rapid prototyping testing

Description

With its plug-and-play setup, the LSPone is very well suited for practical works in education. It is used in Swiss universities.

The aim of this practical work is to learn the technique of rapid prototyping for microfabrication and to test the fabrication by observing the flow of 2 liquids using optical microscopy. The LSPone is used to bring liquids and microbeads in the microchannels that have been fabricated by the students.

Who does this practical and what do they do?

This practical is taught (at different speeds) to bachelor students in the course "Micro et nanotechnologies appliquées" at the HE-ARC and to master students in the course "Microfluidique" at HES-SO, two Swiss universities of applied science. 

It includes the following steps:

  1. Fabricating the mould for rapid prototyping
  2. PDMS moulding
  3. PDMS-glass bonding
  4. Measuring (this is where the LSPone comes in!) using a pump and a microscope
  5. Video analysis
