Teflon septa for scientific sample containment and sealing

DWK Life Sciences (Wheaton) silicone liners White, autoclavable caps have a bonded Teflon-Faced Silicone Liner making them suitable for storage and containment of volatile solvents, sensitive compounds and corrosive chemicals. The liners consist of 0.055” of Silicone and 0.005” of Teflon. They are. Compare this item.

The heavy-duty, flip-top divider box provides easy access to vials, caps, and septa and offers a convenient sample storage center. Clear and amber vials are available. Applications. The 40mL clear or amber vial with a Thermo Scientific Disc is suitable for discrete water sampling under U.S. EPA 40 CFR Parts 136 and 141.

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.

4 mL vials , 12 mL vials, 22 mL vials, or 40 mL vials are available. Choose from either clear glass storage vials or amber glass storage vials. Open top storage screw caps are lined with PTFE/silicone for chemical resistance and excellent seal. Closed storage screw caps (closed storage caps) are PTFE-lined and available together as storage vial

MilliporeSigma. of 6.9 +/- 0.2 at 25C. It can be stored at 15-25C (protected from light) for 12 months. A single box contains 4 bottles of 300 mL of fluid, each bottle with a screw cap with septum closure that reduces the risk of cross-contamination and optimizes the disinfection procedures. Synonyms: Diluting.

Sealing films, tapes and foils are basic consumables common to most wet laboratory setting. Sealing films are designed to protect against oxidation, evaporation, and cross-contamination in cell cultures during processing, storage, and transport. Foils are utilized in multiple ways like covering labware containers and making weighing dishes or

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through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.

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.

Sampling bottles are used for batch drying on a tray and can be connected to a drying chamber or manifold valve ports. Sampling bottles are a great storage option suitable for both short and long-term storage, as well as vaccine containers or freeze-drying. Serum bottles from Thomas Scientific are available in both glass and plastic materials

A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance. PTFE provides increased chemical resistance.

terephthalate (PBT) High Temperature Caps can be sterilized at up to 180°C and have a Teflon® liner for sealing. The Open Top Caps are polybutylene terephthalate (PBT) and require piercible silicone septa (sold separately) for sealing. The Three Hole Delivery Cap has 1/4-28 threads

The C&G 40 mL precleaned VOA (volatile organic compound) vial is mainly used in research laboratories or in chemical industries. It is suitable for use with autosamplers, solid cap and liners for analysis. This L3 vial comes with a 24-414 white PTFE septa cap which offers tight sealing of sample. Compare this item.
