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 IÕve heard of an additional safety device that can also be 
used for this purposeÑthough I canÕt find one.  IÕve 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!
