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
• Level 2: High-throughput analysis When robustness and reproducibility are key SureSTART Level 2 vials have very low metal contents and leachables to ensure that they conform to the high standards you need to meet your regulatory requirements. The septa are conditioned to provide a very low level of chromatographic extractables.
Wilmad-LabGlass™ SP Scienceware™ 5mm O.D. Thin Walled Quartz NMR Tube. Wilmad Precision NMR Quartz Tubes have an extremely low thermal expansion rate and high tensile strength which is 14 times more robust during the cooling/heating process than Type 1 Class A glass tubes. Diameter (Metric) Outer. 4.936±0.0065 mm.
selecting septa. PTFE/red rubber septa are not recommended for multiple injections or for samples that need to be stored for further analysis. When applications require a longer time between injections or any type of standard additions, PTFE/silicone septa are always best. What force is required to penetrate the septum?
Technical Support Customer Service. Replace your worn out septa with Thermo Scientific™ SureSTART™ 20 mm Septa (Level 2). Select Level 2 products for high throughput applications, when robustness and reproducibility are key. Choose from various pack sizes of silicone/PTFE or butyl/PTFE septa manufactured with shore values of 45 and 50
Select Level 2 products for high throughput applications, when robustness and reproducibility are key. Choose from a variety of kits containing screw or short thread screw vials with marking spots in clear or amber glass and polypropylene caps with silicone/PTFE septa of various hardness values designed to reduce autosampler needle issues.
• Level 2: High-throughput analysis When robustness and reproducibility are key SureSTART Level 2 vials have very low metal contents and leachables to ensure that they conform to the high standards you need to meet your regulatory requirements. The septa are conditioned to provide a very low level of chromatographic extractables.

Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene and is a PFAS that has numerous applications. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3]

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.
