You
can try substituting for another liquid, depending on your
application.
I
know a lab that has switched from silicon oil to tetraethylene glycol. It
costs a fraction of silicon oil. It has a flash point of 182 C and boiling
point of 314 C. Since most of their reactions are below 150 C, it works
well for them. It is water soluble so it is easy to handle the small
amount of residue on the surface of a flask.
Be
well,
James

Subject: [DCHAS-L] oil bath
safety
Hello everyone,
Does this group have any tips for safe glassware handling
when using oil baths?
I understand how to handle the heat part, but particularly
tips/tricks for oily / slippery round bottom flasks and how to wipe them
(relatively clean) so they don't get oil everywhere all the
time.....
The specific application is for 2 and 3 liter sized
roundbottom flasks being used on a rotary evaporator - lots of
attaching/detaching is necessary periodically.
Thanks! This group is a wealth of knowledge and
although I've been out of the teaching lab for awhile, I still oversee a lab
that I want to be safe and don't have other scientists around with which to
confer.
