Chromatography Autosampler Vial Caps
Microsolv Technology Corporation Caps, Crimp Top, with 1.0mm thick, Red PTFE / White Silicone Rubber / Red PTFE Septa, fitted in aluminum, Silver Caps. For use with 11mm Crimp or Snap Top, 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.
Microsolv Technology Corporation Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit Septa, fitted in smooth, polyethylene, Natural Transparent Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
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.
Microsolv Technology Corporation Caps, Headspace, Crimp Top, with White Silicone Rubber / Blue PTFE SPME Style Septa, fitted in Steel, Magnetic, Gold Caps with 8mm center holes. For use with 20mm Crimp Top Headspace Vials. 100/PK.
Special Shape Septa with thick rubber outer ring (3mm) and thinned rubber center (1.5mm) provides a good seal with most 20mm crimp top Headspace vials. The target area on this Septa is easer for SPME needles to penetrate, minimizing broken or damaged needles. Recommended with CTC Pal and other autosamplers with SPME or Solid Phase Micro-Extraction injectors.
Microsolv Technology Corporation Caps, Headspace, Crimp Top, with White Silicone Rubber / White PTFE, High Purity Septa, fitted in Bimetallic, Magnetic, Red Caps with 8mm center holes. For use with 20mm Crimp Top Headspace Vials. 100/PK.
High Purity Silicone Rubber / PTFE Septa with Durometer of 45 Shore A, (hardness) and 3.0mm thick with Ultra Low Bleed Rubber that is made with a proprietary process for ultra durability, purity and low extractables. Excellent choice for highly sensitive analyses. The lower Durometer means that this is a softer Septa and therefore better for easier penetrations by autosampler needles. Wide temperature range from -60⁰ to 200⁰C. Bimetallic caps are still magnetic but easier to crimp compared to all steel crimp caps.

Microsolv Technology Corporation Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit Septa, fitted in smooth, polyethylene, Yellow Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
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.
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. 100/PK.
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.

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.
