Great idea. And when
purchasing new condensers etc. consider purchasing ones with removable
hose connections like these GL-threaded
ones.
If you have a
resident glassblower, he or she can retrofit existing glassware with GL
threads quite cost-effectively. If you don't have a glassblower,
but do have a large collection of condensers you can outsource it and it
would cost less than buying all new glassware. It would be a
significant cost per unit, but then again it's probably less
expensive than paying for one or two severed
tendons...

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

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=92ve heard of an additional
safety device that can also be used for this purpose=97though I can=92t
find one. I=92ve 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!
