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 Waters Clear Glass Screw Neck Vial, with Cap and Preslit PTFE/Silicone Septum is manufactured to meet the dimensional constraints for height, breadth, neck aperture, neck center, threads, and bottom thickness required for autosamplers, much like all other Waters vial lines. It is essential that vials adhere to these acceptable limitations

Available as both clear glass vials or amber glass vials , open top screw caps with PTFE/silicone septa, or PTFE lined storage screw caps that offer broad chemical resistance. Our storage screw top vial kits are used extensively in environmental, food, and pharmaceutical applications.

analysis in gas chromatography with FID, TCD and FPD detectors or HPLC with UV/Vis or RI detectors, PTFE/Synthetic Red Rubber septa offer good resealability and excellent chemical inertness before puncture. The low durometer of red rubber allows for easy needle penetration even with thin bore GC needles. PTFE/Red Rubber septa are not recommended

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.
