What are the differences between headspace vials caps/setpa?

  • Hi,

     

    5183-4477 is our standard headspace cap. Because the cap is made from aluminum, it can be easily crimped with manual and electronic crimpers. 8010-0165 and 5190-3987 are both steel, magnetic caps compatible with CTC autosamplers. As they are steel caps, a high powered crimper is needed to crimp them onto the vial. The difference between the two is that septa of 5190-3987 is rated up to 300 C, whereas the septa in 8010-0165 (PTFE/Silicone) is only rated up to 200 C. 

     

    Thanks,

    Jeff
