Glassware used in a chemistry laboratory is special. It needs to resist chemical attack. Some glassware has to withstand sterilization. Other glassware is used to measure specific volumes, so it can't change its size appreciably over room temperatures. Chemicals may be heated and cooled so the glass needs to resist shattering from thermal shock. For these reasons, most glassware is made from a borosilicate glass, such as Pyrex or Kimax. Some glassware isn't glass at all, but inert plastic such as Teflon.

Each piece of glassware has a name and purpose. Use this photo gallery to learn the names and uses of different types of chemistry laboratory glassware.

Beakers

No lab would be complete without beakers. Beakers are used for routine measuring and mixing in the lab. They are used to measure volumes to within 10% accuracy. Most beakers are made from borosilicate glass, though other materials may be used. The flat bottom and spout allow this piece of glassware to be stable on the lab bench or hot plate, plus it's easy to pour a liquid without making a mess. Beakers are also easy to clean.

A boiling tube is a special variety of test tube that is made specifically for boiling samples. Most boiling tubes are made of borosilicate glass. These thick-walled tubes are usually about 50% larger than average test tubes. The larger diameter allows samples to boil with less chance of bubbling over. The walls of a boiling tube are intended to be immersed in a burner flame.

Burets or burettes are used when it is necessary to dispense a small measured volume of a liquid, as for titration. Burets may be used to calibrate the volumes of other pieces of glassware, such as graduated cylinders. Most burets are made of borosilicate glass with PTFE (Teflon) stopcocks.

An erlenmeyer flask is a cone-shaped container with neck, so you can hold the flask or attach a clamp or use a stopper.

Erlenmeyer flasks are used to measure, mix, and store liquids. The shape makes this flask very stable. They are one of the most common and useful pieces of chemistry lab glassware. Most erlenmeyer flasks are made of borosilicate glass so that they can be heated over a flame or autoclaved. The most common sizes of erlenmeyer flasks probably are 250 ml and 500 ml. They can be found in 50, 125, 250, 500, 1000 ml. You can seal them with a cork or stopper or place plastic or paraffin film or a watch glass on top of them.

A Florence flask or boiling flask is a round-bottom borosilicate glass container with thick walls, capable of withstanding temperature changes. Never place hot glassware on a cold surface, such as a lab bench. It's important to inspect a Florence flask or any piece of glassware prior to heating or cooling and to wear safety goggles when changing the temperature of glass. Improperly heated glassware or weakened glass may shatter when the temperature is changed. Additionally, certain chemicals may weaken the glass.

A funnel is a conical piece of glass or plastic that is used help transfer chemicals from one container to another. Some funnels act as filters, either because of their design of because filter paper or a sieve is placed on the funnel. There are several different types of funnels.

Glass bottles with ground glass stoppers are often used to store stock solutions of chemicals. To avoid contamination, it helps to use one bottle for one chemical. For example, the ammonium hydroxide bottle would only ever be used for ammonium hydroxide.

Graduated cylinders are used to measure volumes accurately. The can be used to calculate the density of an object if its mass is known. Graduated cylinders usually are made from borosilicate glass, though there are plastic cylinders, too. Common sizes are 10, 25, 50, 100, 250, 500, 1000 ml. Choose a cylinder such that the volume to be measured will be in the upper half of the container. This minimizes measurement error.

Petri dishes come as a set, with a flat bottom dish and a flat lid that rests loosely over the bottom. The contents of the dish are exposed to air and light, but the air is exchanged by diffusion, preventing contamination of the contents by microorganisms. Petri dishes that are intended to be autoclaved are made from a borosilicate glass, such as Pyrex or Kimax. Single-use sterile or non-sterile plastic petri dishes also are available. Petri dishes commonly are used for culturing bacteria in a microbiology lab, containing small living specimens, and holding chemical samples.

Pipets or pipettes are droppers calibrated to deliver a specific volume. Some pipets are marked like graduated cylinders. Other pipets are filled to a line to reliably deliver one volume again and again. Pipettes may be made of glass or plastic.

Separatory funnels are used to dispense liquids into other containers, usually as part of an extraction process. They are made of glass. Usually a ring stand is used to support them. Separatory funnels are open at the top, to add liquid and allow for a stopper, cork, or connector. The sloping sides help make it easier to distinguish layers in the liquid. The flow of liquid is controlled using a glass or teflon stopcock. Separatory funnels are used when you need a controlled flow rate, but not the measuring accuracy of a burette or pipette. Usual sizes are 250, 500, 1000, and 2000 ml.

Test tubes are round-bottom cylinders, usually made of borosilicate glass so that they can withstand temperature changes and resist reaction with chemicals. In some cases, test tubes are made from plastic. Test tubes come in several sizes. The most common size is smaller than the test tube shown in this photo (18x150mm is a standard lab test tube size). Sometimes test tubes are called culture tubes. A culture tube is a test tube without a lip.

Volumetric flasks are used to accurately prepare solutions for chemistry. This piece of glassware is characterized by a long neck with a line for measuring a specified volume. Volumetric flasks usually are made of borosilicate glass. They may have flat or round bottoms (usually flat). Typical sizes are 25, 50, 100, 250, 500, 1000 ml.

Watch glasses are concave dishes that have a variety of uses. They can serve as lids for flasks and beakers. Watch glasses are nice for holding small samples for observation under a low-power microscope. Watch glasses are used for evaporating liquid off of samples, such as growing seed crystals. They can be used for making lenses of ice or other liquids. Fill two watch glasses with liquid, freeze the liquid, remove the frozen material, press the flat sides together... lens!
