Try our brand new biocompatible polymer with this ready-to-fabricate start pack! The Flexdym is a great alternative to PDMS: self-sealing, resistant, cost-effective and biocompatible, it will greatly ease your work when fabricating chips. Contains 10 sheets of 15 x 15 cm Flexdym polymer.
In this kit, you will be able to try the Flexdym with 10 sheets of 15 x 15 cm as an alternative to PDMS for your chip microfabrication. Different thicknesses are available upon request: 1.3 mm, 0.8 mm and 0.2 mm.
The Flexdym polymer is a real breakthrough for microfluidics
Features & Benefits
The Flexdym is a new polymer which gathers the advantages of PDMS without its drawbacks:
- Biocompatible (ISO 10993-5 & UPS Class VI)
- Self-sealing at ambient temperature: no need to use plasma bonding or high temperatures, you can then add biomaterials prior assembly
- Compatible for optical assays: low fluorescence, optically clear
- No absorption, permeable to gas and not to liquid
- Resistant to tearing: Unlike PDMS, it will not tear apart when you manipulate it
Effective integration, cellular and bio-reagents
The high sealing performances of the Flexdym enable the integration of cells, proteins and others enzymes biomaterials prior to assembly. With a fabrication process that doesn’t involve plasma, vacuum or high-temperature, we can ensure that biological agents remain viable and functional in your device.
- Molding with a hot-embossing system
- Low pressure: below 1 bar
- No vacuum needed
- Easy unmolding
- Full operation takes less than a minute
- Extremely low viscosity for rapid thermal molding with filling rates up to 100-1000 times greater than classical rigid thermoplastics (COC, PS, PMMA,…)
Flexdym is an alternative to any other chip material in the classical applications of microfluidic chips.
This polymer is particularly interesting in life sciences: its biocompatibility make it simple to design any experiment. The self-sealing technology is not destructive, unlike plasma, vacuum or high temperature used in the sealing of other chips.
Optical or fluorescence measurements in a chip require the use of materials that show a high level of transparency (almost 90% transmittance), primarily in the UV and visible range. Flexdym fulfills these conditions. Indeed, it reaches the limit of 50% transmittance (which we considered to be an acceptable limit in transparency) at a wavelength of 295 nm. Flexdym features similar properties to the clearest materials. This transparency window is sufficiently wide for a large number of fluorophores, particularly the most popular fluorescent Cy3 and Cy5 dyes, which have excitation wavelengths at 550 and 650 nm and emission wavelengths at 570 and 670 nm, respectively.

- Do I need a heat press for Flexdym?
Yes, most heat presses or hot-embossers should work. A press that can mold at a pressure of at least 7 psi or above is ideal (a vacuum assisted press is not required). You may have to make small adjustments to optimize molding your chips. We offer a compact microfabrication kit, user friendly and plug and play system. Contact us for more informations.
