Microsolv Technology Corporation Caps, Screw Top, with Orange Red Rubber / PTFE Septa, bonded in "knurled", polypropylene, Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 100/PK.
Orange-Red Silicone Rubber is more economical White Silicone Rubber and softer than Natural Red Rubber which is better for your autosamplers, minimizing damaging needles and injections systems.
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.
Microsolv Technology Corporation Caps, Screw Top, Solid, with a Red Butyl Rubber/ Grey PTFE liner, in "knurled", polypropylene, Black Caps. For use with 13-425mm thread,15x45mm autosampler vials. 100/PK.
Economical Cap turns 15x45mm, 4ml autosampler vials into storage bottles. Butyl Rubber / PTFE liner provides a good inert closure with adequate re-sealing properties.
Microsolv Technology Corporation Caps, Screw Top, with Natural Rubber / TFE Septa, fitted in "knurled", polypropylene, Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 1000/CS.
Natural Rubber does not contain siloxanes like Silicone Rubber. TFE is similar to PTFE when comparing inertness.
Microsolv Technology Corporation Caps, Snap Top, with White PTFE Septa, fitted in smooth, polyethylene, Green Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 1000/CS.
This PTFE (only) Septa is for single injections or non-volatile samples as it will not reseal.
Microsolv Technology Corporation Caps, Screw Top, Solid, with Red-Orange Natural Rubber / Transparent TFE Liner, fitted in knurled polypropylene, Black Caps. For use with ND15 thread, storage Vials or Bottles. 100/PK.
Natural Rubber / TFE Liner is 60⁰ Shore A (hardness) and is 1.3mm thick. Cap can be used for use with Storage Vials or Bottles with 15-400mm screw threads.
Microsolv Technology Corporation Caps, Screw Top, with Orange Silicone Rubber / Ivory PTFE, low durometer Septa, fitted in smooth sided, Robo Style, soft polypropylene, Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 100/PK.
Orange-Red Silicone Rubber is softer than Natural Red Rubber and is better for your autosamplers. Ivory white is inert. Compares to National Scientific / Thermo DP™ Screw Caps.
Microsolv Technology Corporation Caps, Screw Top, with Red PTFE / White Silicone Rubber / Red PTFE Septa, fitted in "knurled", polypropylene, Green Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 1000/CS
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, Screw Top, with Silicone Rubber / PTFE Partial Pre-Slit (Y Shape) Septa, fitted in "knurled" polypropylene, Blue Caps. For use with 9-425 thread, 12x32mm autosampler vials. Excellent for GC and GCMS. 1000/CS.
Partial slit, only in the rubber leaves PTFE to form an evaporation barrier making this a good choice for volatile samples when an autosampler requires a pre-slit Septa.Y shaped partial slit allows for better "resealing" of rubber after initial injection.
Microsolv Technology Corporation Caps, Screw Top, with Silicone Rubber / PTFE Pre-Slit Septa, fitted in smooth sided, Robo Style, soft polypropylene, Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 1000/CS.
Pre-slit for easy penetration by autosampler needles and to prevent "Septa Plunge" into vials.
