PP caps with silicone/PTFE septa.
These MRQ30 total recovery vials deliver maximum sample capacity with minimal residual volume (<1 µL). Vials have 9-mm short thread that sits much higher on the vial allowing you to screw on the caps and still use them in a robotic autosampler. Wide-mouth opening provides a large target area reducing the possibility of bent needles—use with bottom or side draw-port needles.
Vials are made of Type 1, Class A 33-expansion borosilicate glass to give you the highest resistance to chemical attack. Low bleed makes these vials clean enough for LCMS analysis.
