The septum forms a barrier between your sample analyte in the vial and the outside atmosphere. This barrier protects your sample from external contamination while allowing a needle (from a manual or automatic syringe) to enter the vial, and extract the sample for the next stage of separation.
Septa. Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum
Jun 2, 2020 · Jun. 2nd, 2020. HPLC Sample Vial is widely used in Laboratory analysis. Food safety, Environmental monitoring, and HPLC Sample Vials take an important role. This article focuses on the application of glass sample vials for LC and LC/MS and small molecule applications. Please choose a compatible HPLC Sample Vial according to your experiment
PTFE/Synthetic red rubber septa are an economical choice for general GC and HPLC applications. Used primarily for routine 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.
Aug 22, 2023 · HPLC vials, septa, and caps play indispensable roles in the HPLC process: Preserving Samples: Vials act as guardians for liquid samples, shielding their purity during storage and analysis. Injection Precision: Septa act as sentinels, protecting samples from the HPLC system while preventing evaporation, contamination, and interference.
High-performance liquid chromatography (HPLC) is a broad analytical chemistry technique used to separate compounds in a chemical mixture. These separations utilize the pressure-driven flow of a mobile phase through a column packed with a stationary phase. The mobile phase carries a liquid sample through the column to the detector, and compounds

Oct 21, 2022 · Oct. 21st, 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.
