First, make sure the glass is fire polished. Second, put a bit of
soap solultion on the end of the glass. The tubing should slip

Tygon is tricky because dry Tygon exhibits a lot of friction. I have been told that briefly sticking the end of a Tygon tube in boiling water will both soften and lubricate it for the insertion of a glass tube.

Subject: [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!
