CUSTOM ITEM: Caps, Screw Top, with Orange Silicone Rubber / Ivory PTFE, low durometer Septa, fitted in smooth sided, Robo Style, soft polypropylene, Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK.
Additional Info:
The 9502S‑01‑119 screw caps are a custom‑manufactured specialty product designed for laboratories requiring exceptionally soft septa materials to protect autosampler needles, injection ports, and robotic handling systems.
These caps feature low‑durometer orange silicone rubber, which is softer than natural red rubber, helping reduce mechanical stress during needle penetration and repeated injections. This softness is particularly beneficial in high‑throughput autosampler workflows, extended sequences, or automated systems where minimizing wear on injection components is critical.
The septa are faced with ivory‑colored PTFE, selected for its chemical inertness and absence of dyes, providing reliable sample protection while maintaining compatibility with routine chromatographic applications.
Housed in smooth‑sided Robo‑Style soft polypropylene caps, this design is optimized for robotic handling, capper/decapper systems, and automation platforms where knurled caps are unnecessary or undesirable. The smooth exterior supports consistent gripping and torque control in automated environments.
This item is commonly compared to National Scientific / Thermo DP™ screw caps, offering similar automation‑friendly geometry with a custom material formulation tailored to specific method or instrument‑protection requirements.
