With the right flask, chemistry projects are a cinch!

No matter what type of chemistry flasks you need for your laboratory, we have you covered. Ours are all made from borosilicate glass to withstand the high temperatures of many science processes.

Shop the following types of science flask: Erlenmeyer, volumetric, filtering, and Florence (boiling). And learn how to use each different type.

Erlenmeyer: Like beakers, use these to mix, dissolve into solutions, and heat or cool solutions. You can also plug them with stoppers and use them to catch vapor or condensed liquid. Also like a beaker, the graduations are approximate.

Volumetric: With a flat bottom and elongated neck, use these to accurately prepare solutions. They're calibrated to contain a certain volume of liquid. Place a weighed amount of solid chemical at the bottom, and then add liquid solvent you reach the fill line.

Florence: Also called boiling flasks, the body of these are round to provide uniform heating or boiling of liquids. Use them to mix or store solutions as well as collect vapor in distillation processes. Their bottoms can be either round or flat.

Filtering: Use to filter mixtures through a funnel and filter paper. A tube near the top of the neck prevents unwanted pressure buildup. Speed up the process with a vacuum pump.
