Polypropylene vials are used in a wide variety of applications across all market segments including pharmaceutical, environmental, biopharmaceutical, proteomics, and metabolomics. The design of polypropylene HPLC vials is based on how much sample needs to be contained and how much needs to be extracted.
Oct 19, 2015 · The first OOS occurred when a chemist used the caps with non-cut septa on the Shimadzu HPLC. All vials had the first injections with significantly lower areas than the following injections. Prior to this OOS, we allocated the caps with non-cut septa for the Dionex HPLC, and the caps with pre-cut septa for the Shimadzu HPLC.
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.
Quality controlled via a multi-step certification process, we ensure that Waters Certified vials meet and maintain specified levels of cleanliness, glass surface properties, controlled pH shifts and adsorptive losses - from batch to batch and vial to vial.
Purge pump at high flow rate (e.g., 5-10 mL/min.), prime system if necessary. (Prime each pump head separately.) If system has check valve, loosen valve to allow air to escape. If problem persists, flush system with 100% methanol or isopropanol. If problem still persists, contact system manufacturer.

When you shop for lab equipment that vials meet the most stringent requirements for dimensional tolerances, UV cleanliness, and MS cleanliness based on LC/GC standards choose LCGC Certified Clear Glass 12 x 32 mm Screw Neck
Oct 17, 2018 · Abstract The detrimental effect of the interaction between basic analytes and silanol groups on the stationary phases during high-performance liquid chromatography (HPLC) separations has been well characterized, and many new stationary phases have been developed to minimize this effect. Similar interactions can happen between basic analytes and silanol groups on glassware surfaces during
How to Choose the Right Chromatography Vial. Chromatography vials are typically used as temporary sample containers for subsequent gas chromatography (GC) or liquid chromatography (LC) analysis. Consider these factors when choosing the correct vial for your applications.

Headspace vials are the most popular vials for the analysis of gases and are suitable for headspace and SPME experiments. These products are suitable for GC systems. Sample storage Our 4, 8, 10, 16, 20 and 40 mL vials can be used for sample collection and sample storage. We have added a patch to these large vials, making it easy for you to
HPLC: When processing samples in batches of less than 50 use vials as there is little advantage using a 96-well plate as the plate capacity would not be fully utilized. HPLC/UHPLC: Plates are most useful when utilizing a high sample throughput for sample preparation with automated sample handling.
Jul 23, 2020 · By definition, According to the definition, Septa is a circular gasket made of Silicone or silica gel. In HPLC analysis, Septa is usually placed in the Cap of the HPLC Vial to seal the HPLC Vial to ensure that there is no gap between the Cap and the Vial.Aijiren's Septa uses a double-sided material, and the combination of PTFE and Silicone
