Discover a new polymer: FLEXDYM

Flexdym is a copolymer block solution, composed of Di or Triblock according to the different grade. Its similarities with the PDMS but without the drawbacks make it the perfect candidate for microfluidic chips.

We created a Flexdym kit presented here, including all the equipment and accessories to easily and quickly do your Flexdym chips.

  • An alternative to PDMS

  • Transparent and cell culture friendly

  • Highly customizable

  • Very easy to use and to bond

The perfect transition between research and mass production

Flexdym has also been created to offer a solution to companies and research laboratories for transition between research and commercially viable products and thus compatible with mass production.

Indeed the Flexdym has a really quick manufacturing time and it is compatible with well known production facility as hot or roll embossing.


    • Easy to use
    • Really fast fabrication
    • None permanent to permanent bonding without applied pressure down to room temperature
    • Integration 3D fluidic, surface modification, biological reagents
    • Biocompatible PCRs, DNA, proteins, cells culture…
    • Large mechanical and chemical spectrum
  • High impact on master mold accessible technology and cycle time



  • Vacuum heat press
  • Hot plate
  • UVcuring pointer

A spin coater can be added if working with the FLEXDYM liquid solution

Accessories & Chemicals

All chemicals (Flexdym, Isopropanol, Acetone, etc.) and all lab accessories (glass slides, Petri dishes, scalpels, etc.) are included, in order to provide you the most complete set.

We give you all the product references and providers information to refill your stock.

Our specialists selected and adapted the best instruments to make them work together with reliable process. You can find here a short description of the equipment. Please don’t hesitate to contact us to have more information and keep in mind that we have several models to best fit your needs.

More than the equipment in this kit, you can choose different thicknesses of polymer, quickly described here.


Vacuum heat press This is clearly the most relevant equipment for the Flexdym kit. To pattern the Flexdym on the mold you need to heat (170°C) and apply a pressure. Instead of using common manual heat press, BlackHole Lab developed this vacuum heat press adapted to the Flexdym. The vacuum will give enough strength to pattern the Flexdym and it offers an easier, lighter and safer solution than common heat press.
The chuck holder and accessories of the press have been developed to fit the process needs.

In 1 minute, you can easily pattern your Flexdym and get your chip from you glass, silicon, epoxy,… mold!

Major strengths:

  • Easy to use

  • Small (45 x 40 x 16 cm) and light (less than 6kg) to be installed everywhere

  • Quick process under 1 minute


Digital hotplate PDMS membrane bakingThe Flexdym need to be baked to quickly bond to itself, glass or other plastic.

A temperature around 80°C is good but don’t have to be really precise. According to the time used from 15min to 2h you will be able to adapt the bonding strength. Without the hot plate the Flexdym will aslo bond to the surface but in days range. Keep it mind that it’s like a slow but strong adhesive and heating accelerate the process. A simple hotplate is provided to do the job: easy to use for a small price, the perfect ratio.

Major strenghts:

    • Really easy to use

    • Best ratio quality/price

  • Small and light to be installed everywhere


We are providing Flexdym grade Pro. It is adhesive and sticks very well to itself, glass, and some hard plastics through thermal bonding to seal your microfluidic devices.

The Flexdym is for now in three different thickness: 0.3mm, 0.8mm or 1.3mm. All the sheet are at least 15cm x 15cm.

It is possible to buy the Flexdym in a roll format, for this please contact us.

Flexdym is a really easy to use material. It is in the form of films in a shape of about 4 inches square (15x15cm), which is a size adapted to almost all microfluidic devices. The film support enables to have a product which is ready to use, with no need to mix or degas any component.

As PDMS, Flexdym needs a mold to mimic a design. Of course a SU-8 mold can be used but also PDMS itself, Epoxy mold, aluminium…

A simple hot press and few seconds are sufficient to make a microfluidic chip.

Flexdym can be bonded to itself or on other plastics and glasses. This versatility enables to imagine a wide range of devices.


Since each laboratory is different, since each research is unique, we do adapt the offer to be as close as possible to your real need. We discuss together what will be the more efficient facility and, thus, add or remove equipment, accessories, chemicals…

Do not hesitate to ask one of our technico-commercials to make an assessment of your facility and to advise you on your project.


We have created basic offers with everything needed to have a complete working set, but some options or some modifications can be done to better fit your needs.

We gather here a selection of side equipment more suitable for PDMS station.

You can see here the tutorial for our previous process to mold Flexdym. We worked on it and change the main device (heat press) to have a kit that is lighter, cheaper, takes a smaller place and which is safer. You can still get a look at this video to see how simple the process is.
