Oct 21, 2022 · The septa and vial caps are essential parts of HPLC vials. The vial cap serves as a barrier, keeping outside contaminants out of the vial and preserving the integrity of the sample. The septa, a seal between the injection needle and the vial composed of silicone, PTFE, or rubber, ensure accurate and exact sample injection.
Apr 14, 2023 · How do I choose between pre-slit and non-pre-slit septa for chromatography vials? Pre-slit septa are easier to use, while non-pre-slit septa provide better sample integrity. 24.

Pre-slit septa are highly recommended for Shimadzu, Hitachi, and other autosamplers with thin gauge needles. PTFE/Silicone/PTFE Septa: (T/S/T) layer of inert PTFE film is laminated to each side of high-purity, medium durometer silicone to form a septum that is resistant to coring, but still maintains good resealing characteristics.
Aijiren Technologies. Our screw vials and vial screw caps are designed for both HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels, forensics, materials science, biopharmaceutical, proteomics, and metabolomics.

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.
Blue screw cap (9 mm) (PP: blue silicone/clear PTFE septa: 1 mm thickness)—pre-slit, with AVCS technology MSCERT+ kit: 2 mL amber screw glass vial (9 mm short thread) with SureStop technology and write-on patch 6PMCK41W — — Blue screw cap (9 mm) (PP: blue silicone/clear PTFE septa: 1 mm thickness)—pre-slit, with AVCS technology
The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument down time. Don’t let the complexities of septa selection slow you down. Use the simple online Thermo Scientific SureSTART Selection Guide to find the right septa and vial for your analysis.
Mar 17, 2009 · As the Silicone part of the septa represents 95 per cent of the complete septa thickness, the needle can easily penetrate through the Y-slit for most of the septa’s thickness. Only the 0.05mm thick PTFElamination which is uncut, needs to be penetrated by the HPLC needle itself, but this goes without any problems even for these needles.
Jul 31, 2020 · Pre-slit septa is ideal for automatic sampleing because Septa is kept sealed between Vials and Caps, and pre-slit processing makes it easy to puncture the sample feeder's injection into HPLC Vials for sampling. Despite the slit, Septa is also able to maintain the sample seal in HPLC Vial without creating a vacuum in the air pressure inside the
