Decrease your risk of failed analysis and sample reruns
Vials and caps are lot tested by HPLC for cleanliness—certificate of analysis included, complete with chromatogram
Compatible with all autosamplers
Minimal pH shift—vials and closures have a neutral pH factor
Certified vials are tested to confirm that the vials, cap, and septa have been properly manufactured, handled, and packaged for quality results. Short thread vials have a wide opening (6.0 mm) with a unique 9-mm 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.
