When choosing a lab flask, it's important to consider its volume and shape. Some are round and some are conical. Round flasks are used to keep chemicals and solvents from spilling. Pear-shaped flasks are typically used for evaporating solutions to dryness. The rounded V shape of a pear-shaped flask makes it easier to scrape off solids, and it's more convenient to use a syringe to mix the solution. Some lab flasks are made of borosilicate glass, and are intended for storage of chemicals and solutions.

Conical flasks are generally suitable for general laboratory use. They come in four types. Type I flasks are general laboratory flasks. They are designed to be used in most laboratory settings, and have graduated scales and a tapered ground joint. Type II flasks are designed for specific applications, including iodine determination.

Volumetric flasks can range from a few milliliters to two liters. They are calibrated with a calibration line along the narrow neck. The bottom of the meniscus of the flask must be at or below the calibration line to determine its volume.

Despite their unique shapes, conical flasks have a wide base and are commonly used for generating certain mammalian and bacterial cells. These flasks come in a variety of sizes and shapes, and are also suitable for mixing chemicals and solutions. They're designed to be more stable than other flasks, and their wide base prevents spills.
