CUSTOM ITEM: Caps, Screw Top, with Silicone Rubber / PTFE Septa, fitted in smooth sided, Robo Style, soft polypropylene, Black Caps. For use with 9-425mm thread, 12x32mm autosampler vials. BASIK Brand. 1000/CS.
Additional Info:
Designed for high‑volume laboratory operations and automated workflows, these custom Robo‑style screw caps provide consistent sealing performance and efficient system compatibility.
9502S‑05‑K‑M caps are manufactured from soft polypropylene with a smooth exterior optimized for robotic handling, including automated capping and de‑capping systems. The integrated silicone rubber / PTFE septa provide excellent chemical resistance and resealability, supporting repeated injections in HPLC, UHPLC, and LC‑MS workflows.
Supplied in bulk case quantities (1000/CS), this configuration is ideal for high‑throughput laboratories that require consistent consumables for validated methods. These caps are dimensionally compatible with standard 12 × 32 mm autosampler vials using 9‑425 threads and serve as a reliable alternative to widely used industry brands such as National™ / Thermo Scientific™ DP™ screw caps.
