Clinical laboratory OEM

Before PolySource

OEM searching for a material for microplates for high throughput screening that provides clarity to be able to withstand ultraviolet ray transmission, biocompatibility, that is sterilizable, and can provide great dimensional stability.


  • Traditional engineering plastics to not offer the necessary clarity and UV transparency, with very low autofluorescence.
  • Traditional engineering plastics polar substrate promotes adsorption, denaturation, aggregation, or precipitation.

Application Requirements

  • Glass-clear optics that can handle high UV transmissibility
  • Has good bio-compatibility with excellent resistance to aqueous and polar organic media
  • Can withstand high-energy radiation for gamma rays and ETO sterilization
  • Highly challenging tolerance levels that does not promote adsorption, denaturation, aggregation, or precipitation.
  • Complies with global medical and pharma regulations, USP Class VI, ISO 10993, BPA free and FDA compliant.

PolySource Solution


  • TOPAS COC superior optical clarity provides excellent UV transparency and low birefringence.
  • TOPAS COC provides purity, drug compatibility, and biocompatibility
  • TOPAS COC is offers low extractables and leachable, resulting in reliable and repeatable results
  • TOPAS COC offers great processability for intensive tight tolerance parts
  • Unlike other engineering thermoplastics or glass, TOPAS COC offers a non-ionic, minimally reactive surface.

Advantages of New Material

  • Can withstand high throughput screening
  • Repeatable performance

Bottom Line

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