The sealing property of the headspace vial is better than that of the threaded vial, and the rubber or silica gel has good re-sealing after the puncture, so it is ideal to preserve the reagents. If some of the organic solvents in use will corrode the silicone or rubber bottle pad, the bottle pad with PTFE coating is required, if in use, the reagent is not used up once, but stay in the headspace...

High-Performance Liquid Chromatography (HPLC) is a technique widely used in the pharmaceutical, biotechnology, and chemical industries for separating, identifying, and quantifying compounds in a mixture. The success of an HPLC analysis depends largely on the quality of the sample preparation, and the choice of the vial is critical in ensuring accurate and reproducible results. Introducing 2mL...

Headspace vials are one of those rare laboratory supplies that are appropriately named: headspace vials are lab vials with extra space at their top (head). Simple! They're typically used in autosampler machines in chromatography, and for that reason are sometimes called autosampler vials or chromatography vials. Headspace vials are available in two major styles: crimp top and screw thread....

Description of 9-425(9mm) Screw Thread Top vialsAijiren screw thread top sample vial design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called an autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijiren screw...

Aijiren Tech crimps top headspace vials are available in a flat or round bottom style, with clear or amber glass. Headspace closures are available in pre-assembled caps with septums or can be ordered individually. Pressure release, seal with lining, and seal with magnetic lining is also optional. https://www.labanalyticaltesting.com/6-20ml-20mm-crimp-top-headspace-nd20.html The material of...
