Styre Screen® sorbents are formulated utilizing an ultra-clean, highly cross-linked styrene and divinylbenzene copolymer. This polymeric sorbent possesses high analyte capacity by effective utilization of lower bed mass requirements than a traditional silica particle.

Advantages of Styre screen
- No conditioning step - Improved flow rates
- High and reproducible recoveries - pH stable from 1-14
Highly cross-linked sorbent minimizes - Reduced solvent use
bead swelling - High sorbent capacity
- Reduced sorbent mass - Methods for NIDA/SAMHSA 5 Drugs
