Colleagues -

Does anyone have a great recipe and parts list for the construction of a double-walled side-port or bottom-port needle, the kind where the bottom/side port can be sealed by holding inside a 2-3 mm thick vial septa and the rest flushed with He gas?  E.g. for use on Gasbench, Trace Gas, Multiflow, etc.
