Customer
Diagnostic Test Kit OEM

Before PolySource

Microfluidics are the next frontier in analytics and diagnostics. OEM needing a material that provides amazing detail replication and chemical resistance for mass-produced microfluidic devices.

HOWEVER…

  • Traditional engineering plastics do not offer the purity needed.
  • Traditional engineering plastics to not offer the necessary light and UV transparency, with very low autofluorescence.

Application Requirements

  • Chemical resistance to common solvents used in flow cells and microfluidics, including alcohols, DMSO, acids, bases, and water
  • Exceptional light and UV transparency, with very low autofluorescence
  • High purity -high surface to volume ratio, microfluidic assemblies require an extremely pure substrate to minimize contamination and maximize results.
  • High dimensional stability
  • Ability to mold incredibly fine detail replication, Submicron features when needed

PolySource Solution

Features

  • TOPAS polymers have excellent chemical resistance to common solvents used in flow cells and microfluidics, including alcohols, DMSO, acids, bases, and of course water
  • TOPAS COC include exceptional light and UV transparency, with very low autofluorescence.
  • The high purity of TOPAS COC medical grade plastic means that leachables and extractables are lower than other materials.

Advantages of New Material

  • The inert, nonreactive and nontoxic nature of TOPAS medical polymers contributes to the perfect environment for microchemistry.
  • TOPAS resins enable integration of advanced analytical capabilities into your lab-on-a-chip design.

Bottom Line

  • By starting at the beginning and understanding “ALL” the needs, PolySource determined TOPAS COC to be the best candidate ensuring the customer consistent and reproducible performance.
