Chromatography Autosampler Vial Caps Only
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.
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, 40mil Septa, bonded in wide mouth, "knurled", polypropylene, Black Caps. For use with 10-425mm threads, 12x32mm autosampler vials. 1000/CS.
Pre-slit for easy penetration by autosampler needles. This Septa is slightly thinner than most Septa to enhance the ease or needle penetration. 40mil equals 1.016mm.

Chemglass Life Sciences Cap Only, 18mm Headspace, Magnetic, Red PTFE/White Silicone 1.25mm Thick Septa
Cap Only, 18mm Headspace, Magnetic, Red PTFE/White Silicone 1.25mm 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.
