Screw top vials (12 x 32 mm) with 9 mm thread

These vials have a 9 mm thread that allows them to be used with most GC robotic autosampling systems. The thread is higher on the vial and closer together to allow the vials to be used with a shorter cap. The height of the cap is approximately the same as the aluminum crimp seal to allow the arms of the autosamplers to pick up the vial.
  • 40 % wider opening than standard scew cap vials
  • Superior thread design ensures a secure seal
