We made a bold choice to fit both our mission, which is to boost science using microfluidics, as well as our culture, which is to do things our way and to be part of the research community.
We decided to promote and sell our instruments, not through common, boring advertisement, but instead by providing you with:
And then we hope that while surfing our website, some of you will discover our microfluidic brand and fall in love with Elveflow.
Microfabrication techniques for a circular channel
In soft lithography, the fabrication of a mold, often made in SU-8, is required for replicating PDMS microfluidic structures.
Replicating PDMS-based structures first requires the fabrication of a SU-8 master mold that will serve as a patterned template for PDMS casting
How do you perform a successful SU-8 exposure? Here you will find the tips and tricks to do it.
How do you perform a successful photoresist baking? Here you will find the tips and tricks to do it.
How do you perform a successful spin coating? Here you will find the tips and tricks to do it.
The final PDMS layer thickness mainly depends of spin-coating speed and duration.
Here you can find a complete overview of a SU-8 mold fabrication process.
Here you can find a complete overview of a PDMS chip replication.
Unlike photolithography, soft lithography can process a wide range of elastomeric materials, i.e. mechanically soft materials.
A UV Lamp to expose your SU-8 photoresist. You will find here the relevant points to think about.
A plasma cleaner to bond your PDMS chip, you will find here the relevant points to think about.
A spin coater creates a thin layer of photoresist or PDMS, you will find here the relevant information about how to choose one.
You have the choice between glass or plastic photolithography mask, but how do you choose? here is some information to help you with the decision
A hot plate to bake your SU-8 photoresist, you will find here the relevant points to think about.
Every following technology is based on the same system of additive process, every object is built layer by layer after being sliced by an informatic system.
How do you perform a successful PDMS bonding with a plasma cleaner? Here you will find the tips and tricks to do it.
The photolithography mask is an important tool in soft photolithography processes, we explain here how they are made
Environmental and mechanical conditions can affect the overall size of the photolithographic mask considerably when it is polyester film-made, and to a lesser degree when it is glass-made.
There are different techniques to make microfluidic devices. The main ones are etching, thermoforming, polymer ablation and polymer casting
When you talk about microfluidics, some words can be new, we gathered here some common and relevant definitions
A photolithography mask is an opaque plate or film with transparent areas that allow light to shine through a defined pattern
