CUSTOM ITEM: Caps, Screw Top, with 1.3mm thick Silicone Rubber / PTFE Pre-Slit Septa, fitted in "knurled", polypropylene, Black Caps with 5.5mm center holes. For use with 8-425mm thread, 12x32mm autosampler vials. BASIK Brand. 1000/CS. BULK PRICING.
Additional Info:
Optimize high‑volume autosampler workflows with screw top caps designed for reliable sealing and consistent injection performance.
9582S-30C-K-M caps feature a durable knurled polypropylene construction that improves grip and handling during both manual and automated processing. The 5.5 mm center opening provides an increased target area for autosampler needles, helping reduce alignment variability and improve injection consistency across large sample sets.
The 1.3 mm thick silicone rubber / PTFE pre‑slit septa allows smooth needle penetration while maintaining effective resealability during repeated injections. The PTFE layer offers chemical resistance and inertness, while the silicone backing provides flexibility and durability, making these caps suitable for a wide range of HPLC and LC‑MS applications.
