United Scientific™ UniSafe™ Leakproof Laboratory Grade Wide Mouth LDPE Vented Chemical Wash Bottle, Acetone, 500mL (16oz), 4-Color, Pack of 6

Lovely bottle that works as described. Will definitely be purchasing again!

I've been using these for some time now - I use acetone daily in my home shop, and have used quite a few different acetone bottles.Pro: These retain the acetone like a normal bottle and stop it from evaporating. Pretty standard.Con: They vent a bit oddly and the acetone doesn't come out quickly like a typical bottle seems to. A lot of squeezing only results in a small amount of acetone coming out in an erratic spray.So, they'll do the job and they are cost effective. Just not the best I've used.

I really like these acetone bottles. I work with fiberglass a lot so I use acetone all the time and these just make it a lot easier to keep acetone readily available without it evaporating and without having to worry about it splashing all over the place when trying to pour from the drum in the middle of a layup. These are convenient, easy to use and they put acetone where you need it quickly.

This works good if you like a spattered stream of liquid instead of a nice clean even stream. The way they vented this is that the pickup straw does not make a solid air-tight connection to the screw on top (circled in last picture). So it sucks air when you squeeze the bottle and that air gets intermixed with the output stream. When I think vented I expected a very small air inlet hole in the top with a check valve so you could still squeeze out the liquid, but the air could easily re-enter the bottle when you stopped the squeezing. Personally I don't want the air getting mixed in with the stream, but that may not be important to you.

I use these at home, although it says they are lab-grade, for 99% isopropyl. Seems to keep well in these containers and keeps it readily available for me when I need it. No issues, so far.

The media could not be loaded. Pro: Solid professional grade bottle made of LDPE should stand up to a lot of use, even while holding acetone. Very clear labeling with color coded top.Pro/neutral: The venting is a little weird if you're not used to it, but it helps to make sure that changes in pressure and temperature don't mean that fluid will travel up the tube and spill out. Down side is that it sputters a little when actually using it, but that's worth it in my opinion to eliminate spills of acetone while the bottles are being stored.Neutral: The ink used on the bottle is somewhat/mostly resilient to acetone. I used a cotton swab soaked in acetone to rub a little at a test spot, and it did start to come off. However the ink didn't just immediately dissolve or smear, so it should hold up to an accidental splash of acetone, and won't make a sticky smeary mess all over the bottle when it surely does happen.Con: The tube is a little thick. After using the bottle and you release it, air gets pulled back in through the tube, pulling [most of] the acetone back into the bottle. Because the tube is a little thick, air is able to get around the acetone in the tube, leaving some acetone in the tube which can drip out, often several seconds later. Not so much a problem with water or even alcohol, but acetone and others can be very aggressive. When I moved the bottle after using some acetone, this happened and I accidentally dripped some acetone on my ABS keyboard and "redesigned" one of my keys.In the video, I attempted to spray a consistent stream but it sputtered from the venting. This is worse when you're only spraying small amounts. Again, in my opinion that's neutral, just something to know about. At the end however, a moment after I released the bottle, it dripped again from acetone still in the tube- and once again after I stopped the video. You have to at least know that it can happen and take precautions. Set it down where a drip won't hurt anything, and don't be a moron like me and move acetone over your ABS keyboard (probably a good idea regardless). A couple light squeezes after each use to blow out the tube before setting the bottle down can help, is quick, and an easy habit to get into.

Just picked up these wash bottles, and I must say, I'm impressed with their quality and functionality. I've wanted a set of high quality bottles like this for ages, but from McMaster-Carr they're $$$$The wide mouth design of these bottles makes it easy to fill and dispense liquids, and the vented cap ensures smooth flow and eliminates the risk of vapor lock. The bottles are made from laboratory-grade LDPE material, which makes them durable and resistant to chemicals, acids, and bases.Excellent value for money, and the four-color design makes it easy to color-code different chemicals for quick identification. The bottles are also clearly labeled with "Acetone", but you could easily cover over it with a sticker.Overall, I'm very satisfied with these "UniSafe" Bottles. They're well-designed, functional, and durable, which makes them a great investment for any laboratory or workspace. If you're looking for high-quality wash bottles that offer excellent value for money, these are definitely worth considering.I'll definitely be keeping an eye out for more stuff from this brand!

I had the idea to use this to water my houseplants as most of them don't do too well with wet leaves. I used to use similar bottles in school and I always enjoyed using them.These are similar except that they sputter. All of them do and it is very annoying. As I'm not using this with acetone I can't say the same would happen if I was using acetone but it does seem very likely. I would not want acetone to be splattered beyond the intended area.Regardless, it works well enough for my plants but I'd rather find something a bit better.
