Super clean for highly sensitive GCMS and LCMS applications
Vials and caps are lot tested by LCMS for cleanliness—certificate of analysis included, complete with MS scan
Minimal pH shift—vials and closures have a neutral pH factor
Compatible with all autosamplers
Select silicone-free PicoPure Plus septa for MS applications
LCMS certified vials are manufactured using a process that reduces surface activity, improving analytical quantification and minimizing pH shifts in the samples. Surface metals such as sodium and boron that can contaminate samples and interfere with trace analysis are effectively removed. Screw vials feature 9-mm short thread with a unique thread design that allows you to screw on the caps and still use them in a robotic autosampler. The thread sits much higher on the vial allowing space between the bottom of the thread and the shoulder of the vial.
Clear glass vials are made of Type I, Class A 33-expansion borosilicate glass. Amber vials are made of Type I, Class B 51-expansion borosilicate glass and are ideal for light-sensitive samples.
