Additional Info:
The 9502S‑09‑SP MICROSOLV™ Screw Caps are selected for laboratory workflows requiring sealed vial storage rather than autosampler injection. The solid closed‑top cap design eliminates needle penetration points and helps reduce evaporation, solvent loss, and atmospheric exchange during storage or transport.
Manufactured with blue knurled polypropylene caps and an ultra‑clean silicone rubber/PTFE liner, these caps provide chemically inert sample contact through the PTFE surface while the silicone backing improves compression sealing against the vial rim. This liner configuration provides improved sealing performance compared to PTFE‑only liners, especially for volatile compounds and aggressive solvents.
