Caps, Screw Top, with Silicone Rubber /PTFE Pre-Slit Septa, fitted in a smooth sided, Robo Style Yellow Caps. For use with 9-425 thread, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK.
Additional Info:
Pre‑slit septa reduce resistance during autosampler needle entry, helping improve injection consistency and minimize disruption during automated workflows.
The 9502S‑32Y screw caps feature silicone/PTFE pre‑slit septa that support smooth needle penetration while reducing the risk of “septa plunge” during injections. The smooth-sided Robo Style cap design is optimized for robotic handling systems, allowing consistent positioning and reliable cap engagement during high-throughput operations.
The silicone/PTFE septa provide chemical resistance and sample protection across HPLC, GC, LC‑MS, and GC‑MS applications. The yellow polypropylene cap supports easy visual identification while maintaining compatibility with standard 9‑425 thread, 12 × 32 mm autosampler vials. This cap style is comparable to Thermo / National Scientific DP® caps.
