Chemglass Life Sciences Cap Only, 18mm Headspace, Magnetic, White PTFE/Translucent Blue Silicone 3.12mm Thick Septa
Cap Only, 18mm Headspace, Magnetic, White PTFE/Translucent Blue Silicone 3.12mm 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.
Microsolv Technology Corporation Caps, Screw Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit (X Shape) Septa, fitted in "knurled", polypropylene, Yellow Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 100/PK
X Shape Pre-Slit provides a greater target area for needles and are easier to penetrate but do not reseal as well as single slit septa. 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.
Microsolv Technology Corporation Caps, Snap Top, with Red PTFE / White Silicone Rubber / Red PTFE Septa, fitted in smooth, polyethylene, Green Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
This septa was designed for specific, older instruments such as Agilent 1050 and to provide extra cleaning when "wiping" a needle. Also provides a small degree of better resealing after injection compared to Silicone Rubber / PTFE Septa.
Chemglass Life Sciences Poly Crimp Seal, 11mm, Green Cap, PTFE/Silicone Septum
Poly Crimp Seal, 11mm, Green, PTFE/Silicone Septum. A crimp cap constructed of plastic that fits virtually any 11mm crimp sample vial. Use a standard crimping tool to securely crimp the Poly Crimp seal onto any crimp top vial. The Poly Crimp seal also permits an airtight seal by hand without crimping. Although the Poly Crimp seal can work with any crimp top vial, the tighter manufacturing tolerances and quality assurance program with the vials supplied by Chemglass certifies better performance when the cap is used with Chemglass supplied vials.Vials Compatible with Poly Crimp Seals:¿ CV-1108-1232: Vial, 2.0mL, Clear, Snap Seal, 12 x 32mm, 11mm Crimp¿ CV-1168-1232 : Vial, Standard Opening Crimp Top, Clear, 2.0mL, 12 x 32mm, 11mm Crimp¿ CV-1185-1232 : Vial, Large Opening Crimp Top, Clear, 2.0mL, 12 x 32mm, 11mm Crimp¿ CV-1200-1232 : Vial, Snap Ring, 2.0mL, Clear, 12 x 32mm, 11mm Crimp
