Round Bottom Flask

Durable, American-made glass.

We’ve created a variety of unique, American-made round bottom flasks in different styles and volumes to fit the needs of a wide range of laboratories.

All of our round-bottom flasks are made from the highest quality borosilicate glass on the market.

Developed and tested in commercial laboratories.

We carry different options of joint size and number of necks in stock. Through our years of experience in using our own lab and building commercial labs for others, we’ve seen the most common use cases for each style round bottom flask.

We wanted to design custom, superior-quality flasks that could be relied upon for daily use.

Heavily used in labs which need to heat a product as the flask is uniform throughout and provides equal heat over the surface via a heating mantle.

Compatible with our 2-port inlet adapter.

If you would prefer vacuum-filling liquids into your round bottom flask instead of pouring them in, we recommend using our 2-port inlet adapter.
