Hi Joe,

I wash the capillary out using a standard syringe with a hypodermic needle.  I
fill an exetainer vial with distilled water and seal it with an exetainer screw
cap (with a piercable, rubber septa).  Put the gasbench needle into the vial
through the septa and using the syringe, push more distilled water into the
vial to over-fill the vial and drive the water down the gasbench needle and
capillary.  Works for us.

Best wishes,
Alix
