May 18, 2024 · Laboratory glassware, with its wide variety and broad functionality, is fundamental to conducting experiments and analyses. Common types of glassware include beakers, flasks, pipettes, and test tubes—each designed to serve distinct functions.
Mar 17, 2015 · Glassware in the laboratory comes in a range of different shapes and sizes, and is used for a number of purposes. Don’t know your round-bottomed flask from your Florence flask, or your pipettes from your burettes? This graphic has you covered. Below there’s also a little detail on the usage of each. Basic Glassware
Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.

- Measuring Cylinder
- Conical Flask
- Test Tubes
- Round Bottom Flask
- Volumetric Flask
- Filtration Flask
- Funnel
- Separating Funnel
- Burette
This is a plain and simple cylindrical trough made of glass. It is transparent and has a flat bottom. You can find glass beakers in different sizes like 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, and even 1000ml. The glass beaker has readings on the surface to indicate volume levels in the container. It can tolerate heat and also is inert to most solve...
It is similar to a beaker but has a very small diameter and more height. It has graduations on the surface to indicate the liquid volume in it. It is widely used to take a desired volume of liquid into a beaker. Measuring cylinders find their use when the amount of sample to be measured is more than 5ml or 10ml. If less than this, pipettescan be us...
This is a conical-shaped glass apparatus with a round bottom. The conical flaskdoes not contain graduated readings in most cases. It is mostly available in sizes like 25, 50, 100, and 250 ml. Uses: 1. Widely used in titrationslike acid-base, redox, complexometry, etc. Since the mixture requires constant stirring, the sample is taken in a conical fl...
These are the most commonly used glassware in the labs. Test tubesare mostly non-graduated, as one can add the desired volume from a pipette or burette. They are of different sizes, like 5ml, 10mk, 15ml, etc. They have curved bottoms and are not flat like measuring cylinders. They are also required in large numbers as small amounts of reagents can ...
The round-shaped transparent flask with the ability to hold liquidsand has a narrow mouth. Round bottom flasksare available in shapes like 100ml, 250ml, 500ml, etc. Uses: 1. For the distillationof solutions, wherein the substance is taken in the flask and heated from the bottom. 2. For mixing the substances in liquids.
It is a fixed-volume flask used to make molar solutions. The volumetric flasks are round at the bottom with a long narrow neck. See the page formore details on the flask.
The flask is similar to a conical flask with a small vent on the side to connect with a vacuum. Uses:This flask is especially needed for filtration and crystallization of extracts in the chemistry lab.
The funnel, as we know, is equipment to pour solvents and liquids into a narrow-mouth bottle. In the lab, one often needs transparent funnels to pour solvents, powders, and other liquids into other containers. These funnels are very useful as they minimize the chances of waste due to spillage. Uses:This helps in the safe transfer of liquids and als...
Unlike other glassware, a separating funnelis a specially designed apparatus for the separation of liquids. A conical-shaped flask that has an inlet and outlet. It can hold liquid without leaks when closed with a stopper on top. When two or more immisciblesolvents are mixed, the solvents get separated into two layers. The vent at the bottom of the ...
It is a long cylindrical-shaped glass tube with a stopper at one end. This burette hasa uniform diameter all along the length with clearly marked graduation indicating volume. The stopper is fixed before the outlet. Through this, one can extract a desired volume of liquid from it. A burette needs a stand to hold it in place, as shown in the image b...
