CUSTOM ITEM: Caps, Screw Top, with Silicone Rubber / PTFE Pre-Slit Septa, fitted in smooth sided, Robo Style, soft polypropylene, Yellow Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 1000/CS. BULK PRICING.
Additional Info:
Pre‑slit septa reduce resistance during autosampler needle entry, improving injection consistency in automated or high‑throughput workflows.
The 9502S‑35‑Y‑M screw caps feature silicone/PTFE pre‑slit septa that support easier needle penetration while helping prevent “septa plunge” into vials during injection. The soft polypropylene Robo Style cap is designed for improved compatibility with robotic handling systems, allowing consistent orientation and cap engagement. This design is comparable to Thermo / National Scientific DP® cap styles.
The silicone/PTFE septa provide chemical resistance and sample protection across HPLC, GC, LC‑MS, and GC‑MS workflows. The yellow cap color supports easy identification while maintaining compatibility with standard 9‑425, 12 × 32 mm autosampler vials.
