Lab Flask Features

A flask, on the other hand, is similar to a beaker but has a narrow tubular neck towards the top, and sometimes a round bottom.

Of all the various laboratory flasks out there, the Erlenmeyer flask is the most well known. As stated above, flasks come in a wide variety of forms, but its most common characteristic is its wide base and narrow neck. Flask sizes depend on their selected volume and are typically graduated. Similar to beakers, lab flasks can be made of borosilicate glass or polyethylene polypropylene plastics.

Lab Flask Options

Due to their practicality, there are a wide variety of flask types:

  • Reaction flask: round-bottom flasks with specialized necks to connect to other equipment like a reflux condenser. Typically made out of thick glass to withstand pressure, heat, and vacuums.
  • Distillation flask: As the name implies, specialized to handle liquids that are to be distilled. They come in various sizes but are made of a thinner glass to introduce more heat. Also known as a Kjeldahl flask
  • Reagent Flask: either flat or round-bottom and cannot withstand too much pressure or temperature differences.
  • Erlenmeyer flask: Shaped like a cone and come with various volumetric sizes. They are one of the most common types of flask.
  • Volumetric flask: For preparing liquids dependent on volumetric precision.
  • Dewar flask: Come in various shapes and sizes, but their common characteristic is their double-walled feature to create a near vacuum in between the glass.
  • Evaporating flask: Specific for rotary evaporators
  • Powder flask: For drying powdered substances
  • Retorts: An older style of flask used for distillation, but have been largely replaced by other flasks
  • Buechner flask: Similar to an Erlenmeyer flask, but come with a barb at the neck to attach to other lab equipment.
  • Culture Flask: For cell culturing
