Ordinary vials and caps without these safety features may burst. All of our headspace vials have a greater wall thickness and round base which enables them to withstand pressure up to 60 psig. Low-volume sampling can be achieved by using a 6 mL vial and vial adapter.
Aijiren polypropylene certified vials for autosampler use are translucent and chemically resistant. They are the vials of choice for pH-sensitive samples, sodium, or heavy metal analyses. Polypropylene vials come in snap, crimp, or screw styles and can contain sample volumes up to 700 µL while leaving minimum residual volumes of less than 3 µL.
Oct 02, 2015 · At the higher temperatures high quality seals are a condition for reproducible analysis free of siloxane contamination [See CRS Clean Seals for some information about siloxanes in vial septa]. Background – How a Crimper Works: Because of the stringent requirements of headspace analysis crimp caps are generally preferred over screw caps.
