Chromatography Autosampler Vial Caps
Chemglass Life Sciences Cap, Chem Snap, 11mm, Blue, Pre-Cut Septa, PTFE/Silicone
Cap, Chem Snap, 11mm, Blue, Pre-Cut Septa, PTFE/Silicone. Chem Snap Caps include pre-cut septa where only the carrier is cut through in a Y-form, leaving the PTFE lamination intact. 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.
Microsolv Technology Corporation Caps, Snap Top, with 1.00mm thick, Red PTFE / White Silicone Rubber / Red PTFE Septa, fitted in smooth, soft polyethylene, Natural Translucent 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. 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.
