| ==PDMS Lab at DTU Nanolab==
| |
|
| |
| Polydimethylsiloxane (PDMS), also known as silicone, has become a fundamental material for fabricating microfluidic devices with applications in health, chemistry, biomedical sciences and more.
| |
|
| |
| DTU Nanolab has a dedicated laboratory for the processing of PDMS and fabrication of microfluidics located in building 347. The PDMS Lab is part of the PolyFabLab and has been equipped with brand-new instruments funded by the Novo Nordisk Foundation, alongside selected equipment and processes from previous facilities.
| |
|
| |
| The laboratory has 4 different areas:
| |
|
| |
| 1. Non-cured PDMS: All mixtures of PDMS resin and curing agent are prepared on this area. Cellophan film is provided and must be placed on the table ALWAYS when working with uncured PDMS.
| |
|
| |
| 2. Cured PDMS: Only cured PDMS can be handled in this area.
| |
|
| |
| 3. Fume hood: safe area for handling volatile chemicals that are hazardous for human and environment health. The spin-coating machine and the hazardous waste are also located in this area.
| |
|
| |
| 4. Plasma machine: equipment to condition the surfaces for bonding of parts in microfluidic devices.
| |
|
| |
| 5. Storage area: to store chemicals, samples, sample holders, tools, and materials.
| |
|
| |
| 6. Personal protective equipment and emergency shower equipment: googles, lab coats, [https://www.inside.dtu.dk/en/work-environment/physical-work-environment/laboratorier-og-vaerksteder/oejenskylleflasker-og-noedbrusere emergency shower and eyewasher] are provided for the safety of lab users
