The Chemglass CG-1506-23 1000mL heavy-wall round-bottom flask is used for uniform liquid heating. The single neck has a 24/40 standard taper outer joint, and has a 130mm diameter body. Round-bottom flasks provide uniform heating. This flask is made of clear borosilicate glass for durability, chemical- and temperature-resistance, and high mechanical strength under harsh conditions, such as mechanical washing. Borosilicate glass has a low coefficient of thermal expansion and is resistant to thermal stress. The flask meets ASTM International E438, Type 1, Class A specifications for low-expansion borosilicate glass. Boiling flasks are used for heating and boiling liquids, quality testing, sampling, and research, and in lab applications in chemistry, education, research, and life science applications.

Durable!
This is my third round bottom flask, and definitely my favorite so far. It comes down to one feature, as the performance is identical otherwise: Heavy Walls. I'm kinda clumsy, and this thing has already withstood some hair-raising blows with nary a crack. I've also used it for sulfuric acid distillation, which runs at 639°F/337°C using a heating mantle, and it shows no signs of giving up the ghost.

MISLEADING DESCRIPTION!!! Says "3 units" but you only receive ONE UNIT
Description clearly states "3 units" but I only received one flask. The flask is nice, but there are plenty of just as nice flasks for half the price I just paid

Excellent glass
Man this glass just feels like quality. Chemglass is the absolute best when it comes to good quality glassware. I have ordered this flask along with a 34-piece chemistry set from China- this feels like it could drop to the floor and not have a scratch on it, but the same looking flask from the chemistry set looks like it could break in my hand.

Optimistic
Looks good. Not pyrex, buy heavy. Haven't looked closely for consistent thickness. Optimist of it being good for the money.

Another top quality product from Chemglass

A solid flask.
Very good uniform wall thickness, no visible defects anywhere and a professionally ground joint. I highly recommend Chemglass equipment for anyone who wants to do work under a vacuum or with any temperatures above 100c without having to worry about implosions or shattering. Very good quality.

Great round bottom!
It's a great, thick, sturdy flask that fits perfectly with my 24/40 distillation set. My only complaint is that, since I missed the delivery and my apartment has no buzzers, I had to pick it up from a shipping center that, in my location at least, was in a pretty sketchy and hard-to find part of town. But I don't exactly think that's the company's fault, so they get 5 stars anyway! Good piece of equipment.
