Chromatography Autosampler Vial Caps
Microsolv Technology Corporation Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit (X Shape) Septa, fitted in smooth, polyethylene, Light Blue Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 1000/CS.
Soft-Guard™ Septa provide easier penetration of autosampler needles and better resealing than other brands, for longer instrument up-time and fewer missed injections. Pre-Slit Septa are normally recommended for Waters Alliance and Acquity instruments. 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.
Microsolv Technology Corporation Caps, Screw Top, with Red PTFE / White Silicone Rubber / Red PTFE Septa, fitted in "knurled", polypropylene, Red Caps. For use with 9-425mm thread, 12x32mm 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.

Use screw top, magnetic, covered caps and avoid the difficulty in crimping and de-crimping, standard, hard metal, crimp caps. Vials with improperly crimped caps can cause evaporation and data errors; to avoid these caps that are easy to apply correctly, every time.Pre-assembled with a magnetic gold cover over a Blue, 9-425mm, screw cap with a 1mm thick, non-slit, Silicone / PTFE Septa. These screw caps are designed for autosamplers that use a magnetic closure such as the or the Thermo TriPlus™ and can be used with any 9mm, BASIK™, MicroSolv™ AQ™ or RSA™ Brand, Screw Top, 12x32mm, autosampler Vial. Excellent for GC or Headspace analysis.

Perkin Elmer US LLC Pre-Assembled Aluminum Crimp Cap with Low Bleed PTFE/Silicone (White) Septa - Skived Pressure Release, 1000/pk
We offer a variety of GC headspace vials, caps and septa to fulfil your application needs. Our patented vial and cap design incorporates pressure-relief features which guarantee safe operation with the high pressure typically developed during thermostatting. Ordinary vials and caps without these safety features may burst. All of our headspace vials have a greater wall thickness and round base which enables them to withstand pressure up to 60 psig. Low-volume sampling can be achieved by using a 6 mL vial and vial adapter. All PerkinElmer headspace vials are manufactured to specific tolerances that are guaranteed for fit and performance. Note: Due to the patent which PerkinElmer holds on the closures system of the Headspace vials, the caps, septa, and star springs cannot be sold separately.

Perkin Elmer US LLC Zero Dilution Glass Inner Liner for Capillary and PSS Injectors
Inlet liners for split injection have mixing chambers with tortuous flow paths to allow full vaporization of the sample. Deactivating the surface of these liners prevents active compounds from degrading. Packing the liner with wool will trap non-volatile residue and prevent column contamination when analyzing dirty samples. Inlet liners for splitless injection are generally designed as straight tubes, although new designs such as the gooseneck will help contain the sample in the injector. Packing these liners with wool will also help trap non-volatile residue and prevent column contamination. Compatible with the 480, 580, 680 and older Clarus GC models. Not compatible with Clarus 590/690 capillary injector.
