Reliable, repeatable results start here.

Seeing is Believing
Glass-clear, with low autofluorescence and the highest UV transmission of any plastic, TOPAS COC outperforms other polymers, delivering precise analytical results.
Pure Performance
The exceptionally low extractables and inertness of TOPAS COC make it one of the purest polymers available, meeting all major global regulatory requirements. In fluorescence spectroscopy, the very low leachables of TOPAS COC will not interfere with sample analysis.
Details, Details, Details
Need fine features? Even submicron details are possible with TOPAS COC high-flow resin. Excellent dimensional stability ensures critical measurements for reliable test results. Plus, injection molding scale-up is a snap.
