Additional Info:
Reduce adsorption while maintaining cost efficiency with deactivated flat‑bottom inserts designed for routine analytical workflows.
9502S‑05ND inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and undergo a deactivation (silanization) process to minimize active surface sites. This treatment improves recovery of polar and adsorption‑prone analytes compared to standard glass inserts, while retaining the simplicity and affordability of a flat‑bottom design.
With a residual volume of approximately 6 µL in most autosamplers, these inserts are best suited for routine applications where ultra‑low recovery is not critical. The flat bottom geometry provides stable sample positioning and consistent handling, making it a practical solution for high‑throughput laboratories focused on cost control.
Manufactured in an ISO 9001:2015 certified facility, these inserts deliver reliable quality and reproducibility across batches. The combination of deactivation and simplified geometry offers improved analytical performance over untreated inserts while remaining an economical choice.
