Onw way of doing it wich allow easy connection and removal is by using a
compression fitting such as "Swagelok" union or reducing union between the
two tubes (as long as the two tubes have an external diameter that
correspond to a tube diameter of the fitting). You can use an "insert" on
the plastic tube to prevent collapsing of the tube by the compression
fitting and use an O-ring with the back ferrule installed backward on the
glass tube. You can also select the material of the fitting that is
compatible with your chemicals. I have used similar set-up at many
occasion and never have any problem.
Hope it helps

[DCHAS-L] attaching tubing to glass
A step in one of the analyses we do in our lab involves connecting Tygon
tubing to the end of a glass tube. We have Kevlar gloves for this
purpose, but I’ve heard of an additional safety device that can also be
used for this purpose—though I can’t find one. I’ve done the obligatory
Google search with no luck. Has anyone heard of or used anything that
reduces the risk of getting cut while attaching hose/tubing to glass tubes
or rods?
Many thanks; I hope everyone has a great weekend!
