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. 1000/CS.
Additional Info:
Pre‑slit septa reduce resistance during autosampler needle entry, helping improve injection consistency and minimize disruption in automated workflows.
The 9502S‑32Y‑M 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 design is optimized for robotic handling, allowing consistent positioning and improved cap engagement in high-throughput autosampler systems. This cap style is comparable to Thermo / National Scientific DP® caps.
The silicone/PTFE septa provide chemical resistance and sample protection across HPLC, GC, LC‑MS, and GC‑MS applications. The yellow polypropylene cap enables easy identification and maintains compatibility with standard 9‑425, 12 × 32 mm autosampler vials.
