Sampling vials and septa can be a source of contaminants and mistaken frequently as a fiber related problem. We recommend baking out septa at 150 °C for two hours before use and always use pre-cleaned vials for your SPME sampling. Prevent the needle from bending when doing manual SPME sampling by following this procedure:

Septa, caps and liners play a key role in the storage and preparation of samples. They securely seal samples from the external environment while simultaneously allowing injection by sampling . needles. There are a wide array of factors that determine which septa are most suited to your application. Important considerations include: • Type of
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
compatibility, effective sealing/resealing and low penetration force 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
production of vials, caps and septa. Materials commonly used for vials include glass, polypropylene and TPX. Materials commonly used for caps include polypropylene, low density and high density polyethylene, and urea resin. Materials commonly used for septa include PTFE, silicone, natural red rubber, butyl
Our 12 x 32 mm wide opening vials are most popular for economical and effective microsampling. Its polypropylene body has a glass flanged insert molded to the inside, so the sample comes in contact only with the 100 μL high quality glass insert and the septum. Use with crimp or snap caps.
Most versatile needle for autosampler use and resist coring of vial and inlet septa Bevel (Sharp tip) Typically used for manual injections. The tip shape helps reduce septa coring Side Hole (Dome tip with a side hole for sample exit) Usually used for headspace and large volume injections Blunt End or 90º (flat top)
open top closures fit all SUN-SRi 13-425 screw thread vials Pre-assembled septa allows for vacuum release where more than half of vial contents will be removed Integral septum caps are an economical choice for HPLC applications Bonded septa caps resist dislodging during injection during use
Mar 31, 2022 · A very cost-effective option is the PTFE/Synthetic septa, which comes with red rubber. They are often used in standard HPLC and GC situations. In general, you can use these septa in gas chromatography with: 1. FID (a flame ionization detector), 2. TCD (a thermal conductivity detector), 3. FPD (a flame photometric detector) detectors for routine
the process flow. Thus, MicroLiter autosampler vials, caps, septa and inserts are available in a variety of formats, individually, component kits or assembled kits. • Vials with Limited Volume Inserts installed decreases the prep time per sample. • Component kits offer the convenience of one product number for the vial cap and septa.
Pre-slit and bonded septa options are available. Our AVCS™ caps incorporate Advanced Vial Closure System technology to ensure optimal seal compression when closing a vial. Use AVCS screw caps with our SureStop™ vials for effective seals, consistent data, and increased sample throughput.
