    Laboratory Glassware Glossary – Know Your Glassware And Its Uses

    While performing a significant experiment in a laboratory, two things which are extremely important are the quantity of substances and the experiment timing. All of these important points can be ensured with the help of perfectly calibrated and labeled reliable laboratory glassware. There has to be a seamless arrangement of all the lab apparatus along with storage containers to ensure that everything is at its place.

    So here is a brief classification of laboratory glassware with its uses to let you label them and arrange them as per their requirement:

    • Test tubes – As named, it is a slim tube like vessel with a rounded bottom. It can be used to perform a small to medium reaction experiment and for storage. For experiments involving heat emission, a test tube holder is used.

    • Beaker – It is a wide cylindrically shaped graduated container meant for storing liquids. It can be used to store and even heat a chemical over a lab burner. It comes in an array of shapes and sizes.

    • Evaporating Dish – An evaporating dish is a small ceramic dish with a shallow base. It is made from heat resistant glazed porcelain which can be heated over a flame to heat or evaporate a chemical. It is also available in a cylindrical shape with a lip to ease pouring.

    • Flasks – Another very useful laboratory glassware, the Florence Flask or as it is commonly called, a boiling flask has a spherical base and a long slim neck. The base comes in different shapes and sizes such as round and conical. It is used for boiling solutions as the base allows even distribution of heat and the neck lets you hold it easily. Flasks can be arranged with pipettes using corks to obtain different experimental arrangements.

    • Pipette – A pipette is a test tube that is slimmer and longer to allow accurate measurement of liquids. These come in different shapes and sizes; some of which come with a dropper rubber bulb to precisely adjust the amount of liquid in the pipette.

    • Burette – The shape of a burette can be compared to that of a pipette with one difference which is a tap at one end of the tube. This tap lets the user dispense the exact amount of solution from the burette into another vessel just like experiments that involve titration. The tap is controlled with a stop-cock.

    • Condenser – A condenser is a tube contained in another tube with both the tubes insulated so that liquids flowing in each of the tubes don’t mix. This type of construction lets the container perform heat transfer and thus, the temperature of the liquids can be precisely adjusted.

    • Crucible – A crucible lets the user heat a solution at extremely high temperatures. These are cup shaped vessels with a lid to cover. For safe handling of a crucible, a metal holder is needed.

    Highest quality laboratory glassware is manufactured using Borosilicate glass to withstand heat and pressure. To find these basic lab necessities and a lot more, get in touch with us at Rajas Enterprises (India).
