Volumetric apparatus is an essential requirement for quantitative estimations. Different types of glassware are used in quantitative chemistry to measure the volume of liquids. The reason why only glass equipment is used in chemistry is due to their negligible reactivity, high durability, and lesser costs. However, one needs to use these apparatuses carefully to get appropriate readings each time. Along with this, a regular calibration of volumetric glassware is also compulsory to achieve more accurate results.

What would a chemistry lab be without glassware? Common types of glassware include beakers, flasks, pipettes, and test tubes. Each of these containers has its own unique form and purpose. Beakers are the workhorse glassware of any chemistry lab. Beakers aren't particularly precise. Some aren't even marked with volume measurements. A liter beaker will be accurate to within about ml of liquid.

The flat bottom of a beaker makes it easy to place on flat surfaces such as a lab bench or a hot plate. The spout makes it easy to pour liquids into other containers.

Finally, the wide opening makes it easy to add materials to the beaker. For this reason, beakers are often used for mixing and transferring liquids. There are multiple types of flasks. One of the most common in a chemistry lab is an Erlenmeyer flask. This type of flask has a narrow neck and a flat bottom. It's good for swirling, storing, and heating liquids. For some situations, either a beaker or an Erlenmeyer flask is a good choice, but if you need to seal a container, it's much easier to put a stopper in an Erlenmeyer flask or cover it with parafilm than it is to cover a beaker.

As with beakers, these flasks might or might not have volume marked. Test tubes are good for collecting and holding small samples. They aren't typically used for measuring precise volumes. Those meant to be heated directly with a flame are sometimes made from borosilicate glass, but others are made from less sturdy glass and sometimes plastic. Test tubes don't usually have volume markings.

They are sold according to their size and may have either smooth openings or lips. There are different types of pipettes. Unmarked pipettes deliver liquids drop-wise and might not have volume markings. Other pipettes are used to measure and deliver precise volumes. Micropipettes, for example, can deliver liquids with microliter accuracy. Most pipettes are made of glass, though some are made of plastic.

This type of glassware isn't intended to be exposed to flames or extreme temperatures. Pipettes can be deformed by heat and lose their measurement accuracy under extreme temperatures. A Florence flask, or boiling flask, is a thick-walled, rounded flask with a narrow neck. The neck of the flask allows a clamp so that the glassware can be held securely. This type of flask might measure a precise volume, but often no measurement is listed.

Both ml and liter sizes are common. Volumetric flasks are used to prepare solutions. Each features a narrow neck with a marking, usually for a single precise volume. Because temperature changes cause materials, including glass, to expand or shrink, volumetric flasks aren't meant for heating. These flasks can be stoppered or sealed so that evaporation won't change the concentration of a stored solution. Share Flipboard Email. Anne Marie Helmenstine, Ph.
