Adapter allows vessels to be flushed with inert gas while sampling directly through the bore of the T-Bore stopcock. With a 4 mm bore high vacuum glass stopcock with stainless steel constant pressure retention device.

• Very good chemical resistance
• High temperature resistance
• Minimal thermal expansion giving relatively high resistance to temperature changes

Both the glass and PTFE stopcock have 9 mm OD medium wall arms for use with septum stopper.
