Clear EPA glass lab vials manufactured from inert clear Type I borosilicate 33 expansion glass reaching the Environmental Protection Agency (EPA) testing standards. The glass lab vials include white open top caps with bonded Teflon-faced silicone septa, consisting of 0.055" of silicone and 0.005" of Teflon.

Aijiren’s general-purpose septa are made from an enhanced injection-molded silicone rubber material. The septa material, dark red or gray in color, is specified to withstand over 200 automatic injections at an injection port temperature of 350 °C. You can have confidence in your chromatographic results knowing that each lot of septa goes

PTFE/Silicone Septa: (T/S) High quality, pure silicone is laminated to 0.005” thick PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical.

Mar 31, 2022 · PTFE/silicone septa. PTFE/Silicone is an ideal choice for analyzing volatile organic chemicals. These analyses happen at low concentrations or during operation at higher conditioning temperatures. Store PTFE/Silicone septa in a glass Purepak jar to ensure: 1. minimal background, 2. low permeability, 3. and the best performance of any headspace

cleaningthe vials and septa, they should be placed in an oven and dried at 100 °C forapproximatelyone hour. NOTE:Heating the septa for extended periods of time (i.e., more than one hour) or athigher temperaturesshould be avoided, because the silicone begins to slowly degradeat 105 °C). Also, punctured silicone­backedPTFE­lined septa should

PTFE chemical resistance until punctured, then the septum will have the chemical compatibility of silicone Working temperature range from -40 ˚C to 200 ˚C Pre-slit PTFE/Silicone Provides adequate venting to prevent vacuum formation in sample vial, delivering excellent sample-draw reproducibility Eliminates coring from bottom draw needles

Jul 11, 2023 · Yes, Pre-slit PTFE/Silicone Septa are designed to withstand multiple injections without significant deterioration, maintaining their integrity and preventing sample loss or contamination.

Septa are made from different materials. See below for definitions and uses of different types of septa materials. Rubber septa. Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis.

The associated caps are lined with PTFE or PTFE/silicone to restrict impurity contamination. Aijiren storage vial kits offer a high level of chemical resistance. 40 mL vials are popular sample storage vials. 40 mL amber glass vials are most often used in the environmental market segment for onsite sample collection. 4 mL vials are the smallest

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.

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including

Dec 11, 2018 · NOTE: Heating the septa for extended periods of time (i.e., more than one hour) or at higher temperatures should be avoided, because the silicone begins to slowly degrade at 105 °C). Also, punctured silicone-backed PTFE-lined septa should generally not be reused, because some VOCs have high affinity for the silicone

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 septum is provided with a
