Our 1L flask busted and the replacement came shattered in the box so decided to try a different brand. So far we've vacuumed the morning brew for about 5 days. Glass quality does seem much better than others. There are no squirrels present in the glass. Frosted glass seal works as expected. No leaks. In case you're wondering. We use a Buchner funnel to make our coffee. Much faster than gravity. :)

I used this flat bottomed flask in a evaporation experiment using a magnetic spin bar coupled with a standard evaporator which I also bought from Laboy to include a 30 degree neck. I was skeptical about the ability of the flask to deal with quenching water once the molten mass had reacted but it performed flawlessly. Recovery of the water from the solution was 99.4% via the condenser tube. I have used Laboy glassware seldom in the past but am convinced now that the future use will be exclusive in our labs.

useful for multiples states of material. the flat bottom level is perfect

You don't need a cork ring with this flask. Compatible with flat-top heating device, nice and thick glass. Arrived well packed and damage-free. I would buy again. Arbee

Works well holds up under heat and is sturdy (dropped on lab table without breaking).

Exactly what I wanted and expected. Great item for science experiments or essential oil diffusion.

A very solid, well made flask. Perfect for small refluxing.

Very nice, strong and thick

Has been amazing distilling nitric acid
