Molded Septa are manufactured from high quality, low bleed material that uses the same exclusive LB-2 rubber formulation chromatographers are accustomed to using. Design. Solid Disc. Type. Septa. For Use With (Equipment) Low Bleed GC-MS Columns. Temperature (Metric) Max. 350°C.
make PTFE/silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical.
Air sampling and monitoring is an assessment of air quality determined by the measurement of pollutants and particulates in air. It is used in industrial environments to protect workers and prevent environmental and product contamination. When measuring air contaminants, investigators must consider not only the sampling method but also the

Septa. A wide range of serrated and non-serrated septa, and sleeve stoppers are available for use as temporary closures for glassware joints, tubes, bottles, NMR tubes, ampules, and cannulation techniques in air-sensitive chemistry. To protect your valuable contents in the vessels or containers from the atmosphere, our range of septa provide
These septa are used primarily for routine analysis in gas chromatography with FID, TCD and FPD detectors. PTFE/Red Rubber offers moderate resealability and excellent chemical inertness before puncture. The low durometer of red rubber allows for easy needle penetration even with thin bore GC needles.
Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene and is a PFAS that has numerous applications. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3]
