Glass Apparatus Used in Chemistry Lab

Here is the list of 25 Glass Apparatus used in chemistry lab and their uses.

1: Reagent Bottle 

They are used in labs to store chemicals in liquid or powder form in cabnets or on shelves.

2: Beaker

Simple container for stirring, mixing and heating liquids.

3: Measuring Cylinder/Graduated Cylinder 

Used to measure the volume of an object more accurate and precise.

4: Dropper

Used to transfer small quantities of liquid.

5: Filter Funnel / Conical Funnel 

Used to channel liquid or fine grained substances into containers with small opening.

6: Safety Goggles 

Goggles are the primary protectors intended to sheild the eyes against liquid or chemical splash , irritating mists,vapors, and fumes.

7: Flat bottom flask

Flat-bottom flasks are commonly used in  distillation , boiling , and  other heating applications that require a stable base.

8: Round bottom flask

Round-bottom flasks are often used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis.

9: Condenser 

In chemistry, a condenser is laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down. Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction.

10: Thermometer 

laboratory thermometer is used to measure the boiling point and freezing point during science experiments. It is also used to measure the temperature of substances.

11: Separating Funnel

Separatory funnels are used in the lab for liquid-liquid extractions, separating a mixture's components into two solvent phases of different densities. The higher density liquid sinks to the bottom and can then be drained from a valve, leaving the less dense liquid in the funnel.

12: Distillation Adaptor / Vaccum Adaptor 

Laboratory adapters are commonly used in distillation setups, where they connect the distillation flask , condenser , and receiver flask.The adapters enable a secure and airtight connection, allowing for the efficient separation of components in a liquid mixture.

13: Burette 

A burette, also called a buret, is a long, graduated, glass tube marked with measurements and used in chemistry. A burette functions as a tool for measuring both liquids and gases A volumetric burette is a long glass tube, while a piston burette is similar to a syringe.

14: Pipette 

A pipette is a laboratory instrument used to measure out or transfer small quantities of liquid , in volumes of millimeter, microliters. 

15: Watch glass

A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker.

16: Volumetric flask

The volumetric flask is used for measuring accurate volumes of liquid materials for laboratory experiments.

17: Stirring Rod

A stirring rod is used for mixing liquids, or solids and liquids. 

18: Petri dish 

A petri dish is used to culture different types of cells, including bacteria and molds. 

19: Test Tube

A test tube is a clear glass or plastic container that is much longer than it is wide, commonly has a U-shaped bottom, and has an open top. Test tubes are used to hold, mix, and heat chemical experiments.

20: Stalagmometer

A stalagmometer is a glass instrument that measures the surface tension of a liquid, and that was often used to determine alcoholic concentration.

21: Viscometer 

A viscometer or rheometer is employed to measure the flow/deformation behavior of a liquid/viscoelastic food. Viscometers are conventionally used to measure the viscous properties of thin and thick liquids while rheometers are more sophisticated than a viscometer to measure the viscous and viscoelastic characteristics.

22: Fusion Tube 

A fusion tube is a narrow tube that is frequently used in laboratories for sodium fusion and determining the melting and boiling points of substances.

23: Erlenmeyer Flask

Erlenmeyer flasks are used for a variety of laboratory liquid handling applications such as  pouring, mixing , storage, and suspension cell culture. The flask is designed with a wide base and narrow neck which makes it easy to swirl liquids without spilling.

24: Spirit Lamp

Spirit lamps are often used for heating small test tubes, performing flame tests, and for simple chemistry experiments. 

25: U-Tube

U-tube manometer contains water or mercury in a U-shaped tube, and is usually used to measure gas pressure.
