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.
Microsolv Technology Corporation Caps, Snap Top, with 0.04" thick, White Silicone Rubber / Natural PTFE Septa, fitted in smooth, polyethylene, Red Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
Natural PTFE is very pure and does not have dyes that could extract from it. Our most economical Silicone Rubber / PTFE Snap Cap.
Microsolv Technology Corporation Caps, Headspace, Crimp Top, with Grey Butyl Rubber / Partially Laminated PTFE Septa, fitted in Aluminum, Silver Pressure Relief Caps with 8mm center holes. Pharma-Fix. For use with 20mm Crimp Top Headspace Vials. 100/PK.
Shaped, Butyl Rubber with Durometer of 50 Shore A, (hardness) and 3.0mm thick. Partially laminated with PTFE only on the light grey side of the Septa that faces the sample area. Butyl Rubber facing the glass vial provides a very good seal, due to its elasticity. Combining inertness of PTFE and elasticity of Butyl Rubber. This type of Septa is commonly known as Pharma-Fix™ and is temperature resistant from -40⁰ to 120⁰C. Clear lacquered Caps have score lines that will break open at 3.0 +/ 0.5 Bar, for safety. Low cost for budget minded laboratories.

Microsolv Technology Corporation Caps, Snap Top, with 1.00mm thick, White Silicone Rubber / Blue PTFE Pre-Slit (X Shape) Septa, fitted in smooth, soft polyethylene, Natural Transparent Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
Soft polyethylene caps are more pliable than other Snap Caps and are easier to place on the vial. Popular choice when using a large number of caps at one time. These caps may not seal as well as other Snap Caps and should be used with sample solvents with low volatility. 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.
