PTFE septa are rarely used for GC applications. Polyethylene (PE) Septa and Integral Molded Closures Chemically resistant polyethylene septa are usually molded into single-piece caps. The surface for needle penetration is 0.01" thick, allowing for use with most HPLC autosamplers.
For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.
The PTFE/Silicone septum will aid with multiple injections and sample storage due to the superior resealing capabilities. Until punctured, these vials have PTFE chemical resistance, and then the septum offers the chemical compatibility of silicone. This allows for a working temperature of -40 C to 200 C.
The associated caps are lined with PTFE or PTFE/silicone to restrict impurity contamination. Aijiren storage vial kits offer a high level of chemical resistance. 40 mL vials are popular sample storage vials. 40 mL amber glass vials are most often used in the environmental market segment for onsite sample collection. 4 mL vials are the smallest
LCMS Certified Clear Glass 12 x 32 mm Screw Neck Max Recovery Vial, with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk. One of the most important choices you will make during laboratory separations is choosing lab equipment that is consistent with your materials, application, and lab equipment, including your choice in vials.
The preslit PTFE/Silicone septum is recommended for multiple injections with a working temperature range from -40 C to 200 C and eliminates coring from bottom draw-port needles. This septum also provides adequate venting to prevent vacuum formation in the sample vial and delivers excellent sample draw reproducibility. To assure reliable
Septen, PTFE/Silikon/PTFE red PTFE/silicone/red PTFE, septum diam. × thickness 11 mm × 0.040 in., for use with 4mL vial, pkg of 100 ea View Price and Availability
Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis. PTFE is protective layer that once broken exposes rubber to chemical attack.
PTFE/Silicone/PTFE septum is recommended for the most critical applications such as ultra trace analysis or where there is a longer time between injections or for internal standard methods. PTFE/Silicone/PTFE septa provide superior performance with Aijiren 1050, 1090, , or any autosampler employing a large diameter, blunt tip needle.
Features and benefits. Trajan septa undergo conditioning (thermal and chemical) to reduce siloxane bleed. Siloxane bleed can occur during heating, solvent interaction or piercing by the autosampler needle causing the material to become stressed. Septa liners are often laminated with a layer of high chemical resistance material such as PTFE or FEP.
Considering the high cost, FKM is suitable for special applications that have very high requirements for high temperature and corrosion resistance to chemicals and heat transfer oil. References.
