Caps, Snap Top, with Silicone Rubber / PTFE, ultra-pure, Pre-Slit (Star Shape) Septa, fitted in smooth, polyethylene, Light Blue Caps. For use with 11mm, 12x32mm, Snap Top autosampler vials. AQR Brand. 100/PK.
This specially designed septa provides easy penetration by autosampler needles with improved resealing compared to other Snap Caps. The ultra-pure Silicone Rubber and PTFE have no added color producing the highest purity septa on the market with virtually no contamination or extractables.
The Star Shaped (*) slit offers a much greater target area for an autosampler needle to penetrate the septa and offers minimal resistance. It may not reseal as well as other Pre-Slit Septa.
