CUSTOM ITEM: Caps, Snap Top, with 1.00mm thick, White Silicone Rubber / Blue PTFE Pre-Slit (X Shape) Septa, fitted in smooth, soft polyethylene, Natural Transparent Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. MICROSOLV Brand. 1000/CS. BULK PRICING.
Additional Info:
Provide high‑volume efficiency and improved handling with soft snap caps designed for large batch autosampler workflows.
9502C-S30-T-M caps are made from soft polyethylene, offering enhanced pliability compared to standard snap caps. This makes them easier to apply when capping large numbers of vials, improving ergonomics and speed in high‑throughput environments. The natural transparent design allows easy visual confirmation of proper septa placement.
The white silicone / blue PTFE septa feature a 1.00 mm thickness and a pre‑slit X‑shape, increasing the target area for autosampler needles and enabling smoother penetration. This design is commonly recommended for Waters Alliance and Acquity systems, where improved needle alignment and reduced resistance can enhance injection consistency. The PTFE surface provides chemical resistance, while the silicone layer supports resealing, though X‑slit designs prioritize penetration over maximum reseal integrity.
