Srew Top Vials And Closures

Screw thread top vials are made of low extractable Borosilicate glass. Especially suited for research studies where stability of the glass is of prime importance. Vials are autoclavable. Polypropylene caps have a specially designed septum resin facing of PTFE & silicone septa. The white polypropylene is glass-filled to provide extra chemical and heat resistance compared to standard polypropylene. The resin-faced silicone septum is bonded to the cap, providing a permanent connection. 9mm screw thread vials have a 9-425GPI thread and the closure is dimensionally equivalent to 11mm crimp cap vials. This means that they can be used in any autosampler that use 11mm crimp vials. 9mm screw caps have an advantage over 11mm crimp caps because 9mm screw caps can easily be applied and removed by hand and be reused. Clear(amber)vials with or without graduated writing area. Both pre-slit and non pre-slit caps are available.All of Starlab vials are excellent fitted for autosamplers.
