However, substandard vials, caps, and septa can lead to sample loss, Headspace vials . ... Aijiren vials: Better analyte retention over time.

Caution must be taken when setting the vial oven temperature; a high temperature can result in furan forma- tion in the sample during analysis. To reduce this 

Verex offers the lowest ion content possible to reduce sample loss and Screw thread Verex™ vials and caps provide low evaporation and reusability.

Screw Cap and Headspace Vial are required to have high temperature which can avoid excessive evaporation and keep the sample bottle proper sealing.

These headspace vials are made to withstand higher temperatures and internal pressures required for volatile gas analyses. They have very low metal content,
