1. Prepared by:

2. Alcohol
Burner
Is a source of heat. It is a
burner that uses alcohol to
produce fire.

3. A stirring rod or stir rod is a piece of laboratory
equipment used to mix chemicals and liquids for laboratory
purposes. They are usually made of solid glass, about the
thickness and slightly longer than a drinking straw, with
rounded ends. Like most laboratory glass, stir rods are made
of borosilicate (commonly known as pyrex).

4. Beaker
A beaker is a simple container for stirring, mixing and
heating liquids commonly used in many laboratories.
Beakers are generally cylindrical in shape, with a flat
bottom. Most also have a small spout (or "beak") to aid
pouring as shown in the picture. Beakers are available in a
wide range of sizes, from one milliliter up to several liters.

5. Pipette Bulb
Is used to clean the pans of platform balance and get liquid using a pipette.

6. Bunsen Burner
A Bunsen burner, named after Robert
Bunsen, is a common piece of laboratory
equipment that produces a single open
gas flame, which is used for heating,
sterilization, and combustion.[1][2][3][4][5] The
gas can be natural gas (which is
mainly methane) or a liquefied petroleum
gas, such aspropane, butane, or a mixture of
both.

7. The platform balance is a form of equal-arm balance in
which two flat platforms are attached to the top side of
the beam, one at each end. Such a balance has a rider,
or weight, mounted on a bar that has a calibrated scale,
is parallel to the beam, and connects the supports of
the two platforms. This rider is moved along the bar, its
edge marking decimal fractions of the unit weight.
Platform Balance

8. Burette
A burette (also buret) is a device used
in analytical chemistry for the dispensing of
variable, measured amounts of a
chemical solution. A volumetricburette
delivers measured volumes of liquid. Piston
burettes are similar to syringes, but with
precision bore and plunger. Piston burettes
may be manually operated or may be
motorized.[1] A weight burette delivers
measured weights of liquid.[2]

9. Reagent bottles, also known as media bottles or graduated bottles, are containers
made of glass, plastic, borosilicate or related substances, and topped by
special caps or stoppers and are intended to contain chemicals in liquid or powder form
for laboratories and stored in cabinets or on shelves. Some reagent bottles are tinted
amber (actinic), brown or red in order to protect light-sensitive chemical compounds
from visible light, ultraviolet and infrared radiation which may alter or break them
down. The bottles are called "graduated" when they have marks on the sides indicating
the approximate (rarely exact) amount of liquid at a given level within the container. A
reagent bottle is a type of laboratory glassware. The term "reagent" refers to a substance
that is part of a chemical reaction (or an ingredient of which), and "media" is the plural
form of "medium" which refers to the liquid or gas which a reaction happens within, or
is a processing chemical tool such as (for example) a flux.
Reagent Bottle

10. Ceramic Square
Supports hot apparatus to prevent breakage.

11. Rubber Stopper
Supports thermometer and covers the opening of narrow-mouthed
containers.

12. Clay Triangle
A clay triangle is a piece of laboratory apparatus that is
used to support items being heated by a bunsen burner or
other heat source. It is made of wires strung in
an equilateral triangle on which are strung
hollow pipeclay or ceramic tubes. The triangle is usually
supported on a tripod or iron ring. Unlike wire gauze, which
primarily supports glassware such as beakers, laboratory
flasks, or evaporating basins and provides indirect heat
transfer, the pipeclay triangle normally supports
a crucible and allows the flame to heat it directly.

13. Rubber Tubing
Connects a bunsen burner to a gas
outlet

14. Crucible Tongs
Crucible tongs are large pincers made of
welded steel that are used to grasp and take
a hot crucible out of a fire or furnace, or to
move a crucible from one location to
another.

15. Test Tube Brush
A test tube brush is a brush to clean test
tubes. A long slender brush with nylon
bristles. The bristles encircle the brush on all
sides. Care needs to be taken or you can
break the bottom out af the test tube you are
trying to clean. These are very handy in any
science environment.

16. Double Burette Clamp
A double burette clamp is a laboratory
apparatus that is used to hold either a single
burette or two burettes at the same time.
They normally have two single burette
clamps mounted approximately 2 inches
apart on a cross bar to hold two burettes at
the same time.

17. Erlenmeyers are used in chemistry labs for titration, e.g. for pH, as they can be
held and the contents mixed single-handed leaving the other hand free to
addreagent.[4] Erlenmeyer flasks are extremely useful in the lab setting for stirring
the contents by hand by swirling the flask, as the tapered neck prevents spillage of
the contents.
Erlenmeyer Flask

18. Test Tube holder
It is a clamp that holds a test tube -- for
instance to hold a test tube while heating it
without getting burned. It is made from a
thick piece of metal wire that is shaped into
a spring-loaded clamp to securely hold a test
tube.

19. Test Tube Holder
The function of a test tube holder is to hold
the test tubes and keep them in a secure
position without being held by hand. A test
tube is used to hold small amounts of
solution.

20. Evaporating Dish
An evaporating dish is a piece
of laboratory glassware used for
the evaporation of solids and supernatant
fluids,[note 1] and sometimes to their melting
point. Evaporating dishes are used to
evaporate excess solvents, most commonly
water - to produce a concentrated solution
or a solid precipitate of the dissolved
substance.

21. Test tube rack
The function of a test tube rack is to observe
the chemical substance present in different
test tubes. The test tube rack is also referred
to as a test tube holder.

22. Flame Loop
Is used to hold chemicals during flame test.

23. A thermometer (from the Greek θερμός, thermos, meaning
"hot" and μἐτρον, metron, "measure") is a device that
measures temperature or temperature gradient using a variety of
different principles.[1] A thermometer has two important
elements: the temperature sensor (e.g. the bulb on a mercury-in-
glass thermometer) in which some physical change occurs with
temperature, plus some means of converting this physical change
into a numerical value (e.g. the visible scale that is marked on a
mercury-in-glass thermometer).
Thermometer

24. A Florence flask (also known as a boiling flask) is a type of flask used
as an item of laboratory glassware. It is used as a container to hold
liquids. A Florence flask has a round bottom with a single long neck. It is
designed for uniform heating and ease of swirling; it is produced in a
number of different glass thicknesses to stand different types of use.
They are often made of borosilicate glass to prevent cracks or defacing of
the glass. The flask is named after Florence, Italy. Traditional Florence
flasks typically do not have a ground glass joint on their rather longer
necks but typically have a slight lip or flange around the tip of the neck.
A common size of a Florence flask is 1 litre.[1]
Florence Flask

25. Triple Beam Balance
The Triple Beam Balance is a typical mechanical balance.
It has a beam which is supported by a fulcrum. On one side is a pan on
which the object is placed. On the other side, the beam is split into three
parallel beams , each supporting one weight. In measuring the weight of
an object, rather than adding additional weights, each of the three
weights can be slid along the beam to increase their lever arm.
It works just like a tetter-totter. If you have two people of unequal weight,
the heavier person sits closer to the fulcrum to decrease their lever arm.

26. Forceps or forcipes are a handheld, hinged instrument used for grasping and
holding objects. Forceps are used when fingers are too large to grasp small
objects or when many objects need to be held at one time while the hands are
used to perform a task. The term 'forceps' is used almost exclusively within the
medical field. Outside medicine, people usually refer to forceps
as tweezers, tongs, pliers, clips or clamps.
'Forceps' can be used as both the singular and plural form of the word.
(Example: "I need a forceps.") Also, it is not referred to as a "pair" as one refers
to a "pair of scissors". Etymologically, the word derives from the Latin forca,
meaning a snare or trap.
Mechanically, forceps employ the principle of the lever to grasp and apply
pressure.
Forceps

27. Tripod
A tripod lab equipment is a three-legged
equipment that is usually used as a platform
to hold various flasks, beakers and other
glassware during experiments. It is made of
a strong material such as aluminium.

28. A funnel is a pipe with a wide mouth, good for feeding, often conical mouth and a
narrow stem. It is used to channel liquid or fine-grained substances into containers
with a small opening. Without a funnel, spillage would occur.
Funnels are usually made of stainless steel, aluminium, glass, or plastic. The
material used in its construction should be sturdy enough to withstand the weight
of the substance being transferred, and it should not react with the substance. For
this reason, stainless steel or glass are useful in transferring diesel, while plastic
funnels are useful in the kitchen. Sometimes disposable paper funnels are used in
cases where it would be difficult to adequately clean the funnel afterward (for
example, in adding motor oil to a car). Dropper funnels, also called dropping
funnels or tap funnels, have a tapto allow the controlled release of a liquid.
Funnel

29. A volumetric flask (measuring flask or graduated flask) is a piece
of laboratory glassware, a type of laboratory flask, calibrated to contain a
precise volume at a particular temperature. Volumetric flasks are used for
precise dilutions and preparation of standard solutions. These flasks are
usually pear-shaped, with a flat bottom, and made of glass or plastic. The
flask's mouth is either furnished with a plastic snap/screw cap or fitted with
a joint to accommodate a PTFE or glass stopper.
Volumetric flask

30. A graduated cylinder, measuring cylinder or mixing cylinder is a piece
of laboratory equipment used to measure the volume of a liquid. Graduated
cylinders are generally more accurate and precise than laboratory
flasks and beakers. However, they are less accurate and precise than
volumetric glassware, such as a volumetric flask or volumetric pipette. For
these reasons, graduated cylinders should not be used to
perform volumetric analysis.[1] Graduated cylinders are sometimes used to
indirectly measure the volume of a solid by measuring the displacement of
a liquid.
Graduated Cylinder

31. A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces
of laboratory glassware, such as test tubes and round bottom flasks.
Wash bottles are sealed with a screw-top lid. When hand pressure is applied to
the bottle, the liquid inside becomes pressurized and is forced out of the
nozzle into a narrow stream of liquid.
Most wash bottles are made up of polyethylene, which is a flexible solvent-
resistant petroleum-based plastic. Most bottles contain an internal dip tube
allowing upright use.
Wash Bottles

32. Iron Ring
An iron ring, sometimes called
an iron support ring, [1] is used
in chemistry labs to stabilize
flasks mounted to a ring
stand.[2]
Some iron rings include a
clamp, while others require a
utility clamp to attach to a ring
stand.

33. Watch Glass
A watch glass is a circular, slightly convex-concave piece of glass used in chemistry
as a surface to evaporate a liquid, to hold solids while being weighed, or as a cover for
a beaker. The latter use is generally applied to prevent dust or other particles
entering the beaker; the watch glass does not completely seal the beaker, and so gas
exchanges still occur.
When used as an evaporation surface, a watch glass allows closer observation
of precipitates or crystallisation, and can be placed on a surface of contrasting colour
to improve the visibility overall.
Watch glasses are also sometimes used to cover a glass of whisky, to concentrate the
aromas in the glass, and to prevent spills when the whisky is swirled.[citation needed]

34. Iron Stand
Supports the iron ring or
clamp

35. Wire gauze
used for supporting beakers and flasks when
they are being heated with a Bunsen Burner .
They are constructed of a metal mesh screen
that contains a ceramic fiber circle in the
center that can withstand extremely high
temperatures.

36. Dropper Pipette
Used to transfer small amounts
of liquids to another container

37. Spot Plate
Reaction vessel used for small amounts of substances, especially when
using litmus paper

38. The mortar is a bowl, typically made of hard wood, ceramic or stone.
The pestle is a heavy club-shaped object, the end of which is used for
crushing and grinding. The substance to be ground is placed in the mortar
and ground, crushed or mixed with the pestle. Sometimes referred to as an
"Apothecary Grinder" by individuals unfamiliar with its use, the proper
historical name is "mortar and pestle". The mortar and pestle is usually
utilised when cooking and when crushing ingredients for a certain drug
in pharmacies. It can also be used in masonry and in other types of
construction.
Mortar and Pestle

39. Spatula
Used for getting solid chemicals from reagent bottles.

40. A crucible is a ceramic container capable of withstanding extreme
temperatures, whilst the cover is designed to prevent heat escaping
from the crucible itself. Crucibles are used for a range of purposes, and
are particularly common amongst chemists for the chemical analysis
of various substances
Crucible and Cover

41. Fish Tail
Fish Tail is a Laboratory apparatus inserted
to a Bunsen or a gas burner to spread the
flame.

42. A bell jar is a piece of laboratory equipment
used to contain vacuums.[1] It can be similar
in shape to a bell, and can be manufactured
out of a variety of materials (ranging from
glass to different types of metals). A bell jar
is placed on a base which is vented to a hose
fitting, which can be connected via a hose to
a vacuum pump. By pumping the air out of
the bell jar, a vacuum is formed.

43. Glass tubing
delivery tubes
Used to make droppers for capillary tubes.

44. Desiccator
Used for removing the moisture from
specimens

45. Syringe
Is used for sucking and expelling liquid in fine stream

46. Measuring pipettes
Measures exact volume of liquids

47. Transfer pipette
Used to transfer liquids
