I use a manifold (model WMF6000) that has Luer-lock syringe ports for 14
needles, made by S4J. I bought a flow meter from Cole Parmer.
Connect helium tank to manifold, stick a needle going nowhere in each of
the exetainers to serve as a vent, impale the vented exetainers onto
similar needles projecting from syringe ports, adjust flow. Be sure to
cap unused ports. When done flushing, remove the 2 needles from each
exetainer at the same time.
This is a variation on a manifold used in Gilles St. John's lab.
You might be able to connect several of these manifolds together.
I can send a picture if you like.

Subject: [ISOGEOCHEM] Offline Exetainer Flushing
Has anyone developed an off-line method for flushing a full batch
(96) of exetainers? I am unsure of the cost of a stand alone CTC
Analytics PAL autosampler. It would be great to free up the
Gasbench-IRMS for only measurements and let the exetainers/tubes be
prepped separately. Any thoughts?
