Autosampler vial septa, 13 mm for use with 13-425 threaded caps or 13 mm snap/crimp caps.Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly

Pre-slit septa are highly recommended for improving injection to injection reproducibility with autosamplers withdrawing greater than 50µL of sample from a 2mL vial, due to possible cavitation (vacuum). Pre-slit PTFE / Silicone Septum. In order to pierce easily. Diameter: 8mm to 22mm. Thickness: 1mm, 1.5mm, 3mm.

Silicone plasticizers (e.g. Plasticizer 100 from Wacker Chemie AG) are added to silicone compositions in order to tune the ultimate mechanical properties of the elastomers as well as to improve the processability of the premix composition. Sometimes, simple non-reactive silicone-based (in rare cases non-silicone-based) oligomers and polymers

Suba-Seal ® silicone rubber septa offer improved chemical resistance compared to natural rubber. Suba-Seal ® silicone rubber septa with turnover flange grips outside of the container neck promote a double seal in conjunction with annular serrations on the hollow plug. The annular serrations of the septa depress themselves against the inside

The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.

Jul 1, 2016 · Septa for Inlets. Arguably the most stressed-out parts of a GC system, inlet septa are tasked with maintaining a leak-tight seal between the atmosphere and carrier gas while not introducing significant contaminants into the carrier-gas stream-all of this while heated to upwards of 250 °C and being repeatedly punctured by sharp needles.

the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE/silicone septa Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a
