00:00So, I've been down a bit of a rabbit hole lately, hunting for lab glassware that doesn't crack the second
00:05you put it on a hot plate, and honestly?
00:07The prices out there are all over the place.
00:10So I did the digging for you.
00:13These are the top 5 glass Erlenmeyer flasks for chemistry labs right now, all of them borosilicate, all of them
00:19insanely well-reviewed, and some of them cost less than a cup of coffee.
00:23Let's get into it.
00:25First up, we've got this one-piece borosilicate conical flask that comes in basically every size you could want, 50,
00:31100, 150, 200, 250, 300, 500, all the way up to a full liter.
00:38What I really like here is the consistency.
00:42Nearly 5,000 of these have sold and it's sitting at a perfect 5-star rating, which tells you the
00:47wall thickness and the pourspouts are actually reliable batch to batch.
00:51At around $9.70, it's not the cheapest on this list, but if you want one flask you can heat,
00:57swirl, and autoclave without babying it, this is a solid pick.
01:01Next, this one might be the best value on the whole list.
01:05It's a G3.3 borosilicate conical flask, and the size range is honestly ridiculous, it goes from 50 milliliters all
01:12the way up to 5 liters.
01:145 liters.
01:16That's a serious piece of glassware for a lab or a homebrew setup.
01:20And the price?
01:23$4.54.
01:25Almost $4,800 sold, 5 stars across the board.
01:29If you're building out a set of flasks from scratch and you don't want to spend a fortune, start here.
01:35The graduations are clear and the glass handles thermal shock like it should.
01:40Now, if you just need something small for titrations or quick reactions, look at the HUAOU.
01:45It comes in 25, 50, and 100 milliliter sizes, made from proper borosilicate 3.3 glass, and it costs $0
01:53.71.
01:55I'm not exaggerating, under a dollar.
01:58At that price you can buy 10 of them, break a few, and still come out ahead.
02:03Over $4,600 sold with a 5-star rating, so this isn't some fragile knockoff.
02:08For students, hobby chemists, or anyone who just needs a bunch of small flasks in rotation, it's a no-brainer.
02:15Coming in at number 4, this laboratory borosilicate conical flask covers 50 through 1,000 milliliters and runs about $10
02:22.06.
02:24It's the priciest one here, so what are you actually paying for?
02:28Heavier, more uniform glass and a really clean rim finish, the kind of thing that matters when you're stoppering it
02:34or fitting a rubber bung.
02:36$4,500 sold, perfect rating.
02:39If this is going into a working lab where it gets used daily and cleaned aggressively, that extra couple of
02:44dollars buys you durability you'll notice.
02:47And last up, the thickened borosilicate 3.3 flask.
02:51The whole selling point is right in the name, Thicker Walls, built for high temperature resistance.
02:57If you're doing anything involving direct heating or big temperature swings, that reinforced glass gives you real peace of mind.
03:04It's $6.41, sitting at a 4.9-star rating with over $4,400 sold.
03:10That's slightly lower rating?
03:13Mostly just shipping complaints, not the glass itself.
03:16For heat-heavy work, this is the one I'd grab.
03:20Alright, that's the 5.
03:22I've dropped links to every single one of these down in the description, so go check the current prices, they
03:28move around a lot.
