Dripping wash bottles
Hi all,
I find that plastic wash bottles constantly drip whenever they contain volatile liquids like IPA or acetone. This includes ones which are specifically
designated as being for these liquids. This happens even if they are not exposed to direct sunlight or large temperature changes. It can be very
dangerous as a fire hazard and quite a nuisance. Does anyone know a way to prevent this? I would have thought that these containers could be designed
with some kind of valve to vent the vapor automatically.

I have the same problem, the leakage isn't that bad though. Usually I just loosen the cap to equalize the pressure and it doesn't leak for a few days
or weeks. You could always get these if you are that concerned though

Having a couple bottles shouldn't pose a massive risk... Maybe if you had bins with 15-20 of each solvent bottle dripping but otherwise I've never had
problems, home or workplace labs.

I had
the same issue of solvents (acetone, MeOH, EtOH) dripping from wash bottles, simply <em>solved</em> as
<strong>Mailinmypocket</strong> suggests, by partially unscrewing the caps when not in use.

Agreed, loosen the cap a little. Sucks to be in the middle of cleaning and grab the bottle with the loose cap and have your other hand in use but
that's the way it is.

At work we have little white rubber caps that go on the spout to stop drips. Unfortunately I have no idea what they are called or where to buy them.

I guess if one was really bothered by it they could take small rubber stoppers and poke holes with nails into them. Then just press that onto the
spout....

You can buy non-drip wash bottles.
In my observation they are awful.
They drip anyway when you have used them and they don't let you dispense solvent with any precision.
Here's the sort of thing I mean

I'd strongly recommend not buying them.
