Chemglass Life Sciences Cap, White, Solid Top, 15-425, with 0.60" PP/PTFE/Silicone SURE-LINK Septa
Cap, White, Solid Top, 15-425, with 0.60" PP/PTFE/Silicone SURE-LINK Septa. These caps, made of polypropylene, are ideal for use with volatile solvents, sensitive compounds, and biological media. The SURE-LINK process welds each cap with a Polypropylene/PTFE/Silicone liner bonded to the cap. This process allows the cap to maintain seal through multiple autoclaving operations or cleaning procedures without the use of adhesives. Caps are ideal for storage of samples for prolonged periods of time. They are autoclavable at 121C.

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.
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.
