Colpak-Borosilicate-Glass-18mL-Vial-Clear-TC90-A-with-9mm-Blue-Screw-Cap-Silicone-White--PTFE-Red-TC96-BA-Case
Colpak 9mm screw thread vials have a 9-425 GPI thread and the closure is dimensionally equivalent to 11mm crimp cap vials. This means that they can be used in any auto sampler that uses 11mm crimp cap vials. 9mm screw caps have an advantage over 11mm crimp caps because 9mm screw caps can easily be applied and removed by hand and they can be reused.
