Chromatography Autosampler Vial Caps Only
Microsolv Technology Corporation Caps, Screw Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit Septa, bonded in "knurled", polypropylene, Red Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 1000/CS
This is our Pre-Slit Screw Cap for autosampler vials. Pre-slit for easy penetration by autosampler needles. Recommended for Waters Alliance & Acquity instruments. Soft-Guard™ Septa are easier to penetrate by autosampler needles, and re-seals better than other Caps on the market. This provides longer instrument up-time, fewer missed injections and more consistent data. Use for HPLC, GC, LCMS or GCMS.

Chemglass Life Sciences Cap Only, 18mm Headspace, Magnetic, Red PTFE/White Silicone 1.25mm Thick Septa
Cap Only, 18mm Headspace, Magnetic, Red PTFE/White Silicone 1.25mm Thick Septa. Magnetic Headspace Caps with Septa: (All Silicone is Low Bleed)The 18mm magnetic screw caps are designed for use with any autosampler using a magnet to transport the vial from station to station. The closures are preassembled with a variety of septa.Magnetic Screw Caps with Pre-Cut Star Septa:Preassembled closures include pre-cut septa where only the carrier is cut through in a Y- form, leaving the PTFE lamination in tact. The unhurt PTFE lamination gives 100% protection to the sample while leaving a 0.05mm thick PTFE portion remaining for needle penetration. The Y-form in the pre-cut silicone allows for a better flow of air during sample pick up in order to avoid a vacuum in the vial. Designed for use with any autosampler using a magnet to transport the vial from station to station.
