10 Common Glasswares and Equipment in the chemistry laboratory
There are various Common Glassware and Equipment in the chemistry laboratory
The glassware and pieces of equipment used in the chemistry laboratory are actually many but they have specific uses.
This is a complete list of piecces of apparattus used in chemistry to demostrate titration
For example, the delivery tube is used to bubble gases over water equally for the transport of gases while the gas jar is used to collect gases prepared in the laboratory.
I will like to focus on glassware apparatus and their uses in chemistry laboratory.
Why do we prefer glass wares apparatus to plastics?
Firstly glass wares are of higher quality than plastics and as such may be a little more expensive but some experiments are highly recommended to be performed using glasswares for specific reasons;
1. Glassware pieces of apparatus are very transparent and as such experiments could be monitored easily
2. Glassware can resistant to high temperatures and such appropriate for heating
3. Glass cannot react or interfere with the experiments ( for example in the preparation of nitric acid, the setup is all made of glasswares because the acid will rea t with any other materials)
4. Glasswares are easy to mold or reshape and as such can be made into different sizes and shapes to suit specific experimental reactions.
5. Plastics are not environmentally friendly
Let me use the acid-base reaction (titration) as an example; what are the common glasswares used in titration
What are the glassware used in titration?
Titration is one of the basic experiments, we do in level chemistry.
Titration setup requires the inclusion of pipette burette, conical flask, reagent bottles, and retort stand.
For example, the following pieces of apparatus are used in theexperiment
Conical flask -contains the solution
Burette – for acid
Pipette- for the base
Reagent bottles- indicator and reagent
Retort stand ( not glassware)- to support the burette
What is titration and titration set basic?
Take a look at the titration setup and see what the arrangements look like.
What are the basic Chemistry lab glasswares names and uses?
I will just list the basic glassware pieces of apparatus and pictures to help you understand better.
These are the Chemistry lab glasswares list with pictures.
A common calibrated glassware with a tap or Bob at the end users mainly in titration for dispensing acids or any other liquid. There are about three types of burette; volumetric, piston, and digital burette
Burette is a vital apparatus for quantitative measurement.
2. Pipette :
This is basic glassware equipment used in the chemistry laboratory.
The pipette is not graduated but there is a mark that shows the 20cm3 or 25cm3 capacity mark.
The pipette is used for transferring specific volumes of liquids during experiments.
Though we have different types of pipettes like graduated, dropping, disposable, multichannel etc
A beaker is calibrated glassware with a lip used in mixing liquids and heating solutions.
4. Conical flasks:
This is a cone-shaped flask with a flat bottom sometimes called the Erlenmeyer flask.
This titration flask is used to hold and measure liquids in the labs during experiments.
5. Measuring cylinder:
A graduated narrow cylindrical cylinder used for measuring the volume of liquids.
The graduated cylinder which is otherwise called the measuring cylinder is not very accurate
6. Delivery tubes:
A thin glass tube made of glassware is used for bubbling a gas over liquid or allowing a gas to pass through it onto another container.
7. Flat and round bottom flasks:
Flat and round bottom flasks serve the same purpose but there is a difference in their shapes.
What is the difference between a round bottom flask and a flat bottom flask?
The major difference between the flasks is that the round bottom flask is spherical in shape or has a spherical base and as such cannot stand on its own whereas the flat bottom flask has a flat base and can stand on its own.
Both flasks are usually used for heating though the round bottom flask is better for even distribution of heat.
8. Desiccators and drying pistols
Desiccators and drying pistols are usually used to dry wet reagents or substances in the laboratory.
The Desiccators also protect hygroscopic and deliquescent substances from getting in contact with moisture acid are also used to ensure an airtight seal of the desiccators.
What is a laboratory Condenser?
A condenser is a laboratory apparatus used to convert vapors that is, turn them into liquids – by cooling them down.
10. Volumetric flask:
Volumetric flasks are mainly used for preparing the standard solutions.
It is mainly used to make up solutions to a known volume.
I have explained the common chemistry lab glassware list used in chemistry but the list is not the whole.
