One of the most common mishaps in chem/bio labs is accidentally bumping a measuring column. Given its shape, it almost always breaks when it hits the table on which it rests. Since its contents can often be corrosive, poisonous or biologically hazardous, it's not just the loss of a pricey bit of glassware but also the risk to workers.
A common safeguard is to mount a rubber collar near the top of the column to at least forestall breakage in the event of a bump. I suppose such collars can be bought from laboratory supply houses but far simpler is to cut a piece off a pool noodle, trim the hole to size, and slip it over the column.
IMO, every shop should have a pool noodle or two. Do a bit of gedanken-designing and I'm sure you'll come up with an application or two. Here's one of my recent uses...
