Common Laboratory Apparatus and its Uses

laboratory apparatus

Laboratory equipment refers to the various tools used by scientists to carry out experiments and other research activities. Many types of apparatus are used for scientific work in laboratories. however, we have compiled all possible and comprehensive lists of 50 common laboratory apparatus and their uses. we include different items like microscopes, test tubes, beakers, Bunsen burner, spatula, and much more.

these tools enable us to carry out experiments successfully and make accurate measurements or observations. all common lab apparatus should be drawn in outline only and in their correct proportions.

In many cases, the specific apparatus used will be determined by the nature of the experiment being conducted. For example, a microbiologist studying bacteria will need to use a microscope, while a chemist studying the properties of a new compound will need to use test tubes and beakers.

Some of the items of common laboratory apparatus used in the laboratory are shown below. Names and functions of the apparatus used in  the laboratory are:

Bunsen burner

A Bunsen burner is a source of heat or mechanical appliances for which absolute safety is required while using Bunsen Burner. it is linked to a flammable gas source. Mostly a knob is used to adjust the gas flow amount and a pivot collar that manages airflow. Both the knob and collar must be adjusted to get an excellent flame for heating things.

Test Tubes

A test tube is a glass tube with one end closed and the other end open. The closed-end is in a round shape. Test tubes are used in laboratories to hold small samples. They are mainly used for qualitative comparison and assessment.

A very commonplace to see test tubes is the biochemistry lab. When large numbers of the sample are needed to be compared and tested, these test tubes are used to make this easier. They are also easily covered or capped with a glass or rubber stopper.

Safety Tip: Never heat a covered or capped test tube.

Beakers

Beakers are a very common laboratory instrument and are widely useful in the laboratory as a reaction container. they are also used for holding liquid and solid samples or catching liquids from different titrations or filtrates from filtering operations. A beaker is a simple can in most labs. It is used for heating, stirring, and mixing chemicals. Most beakers have spouts on their rims for easy pouring.

They also usually have lips around their rims and markings to measure the volume of liquid they contain. They are not a piece of proper equipment to measure liquids. Beakers are available in a wide range depending on their sizes, such as 50cm3, 100cm3, 250cm3, or 500cm3 are available.

Beaker Tongs

Have you ever needed to grab something hot?

Or pick up a beaker that is heavy and full of liquid?

If so, then these beaker tongs are perfect for your needs! They are made out of stainless steel with silicone grips at the ends. These tongs will allow you to safely handle anything in your lab without getting burned or spilling your experiment!

Titration flasks

It is also known as a Conical Flask. The Erlenmeyer flask was titled in 1861, after its inventor. It has a slim neck and widens toward its base. This allows easy swirling and mixing of the flask without too much possibility of spilling.

The narrow opening also allows the use of a glass or rubber stopper. It can comfortably be clamped to a ring stand as well as shaken or heated easily. Once again, the numberings on the side are meant mainly for estimation not for precision.

Safety Tip: A significant safety tip here is to never heat the flask while it is covered. This causes pressure build-up that results in an explosion.

Funnels

A lab funnel is also like any other funnel but it was specially designed to be used in a laboratory. They are made up of glass or plastic and have either a long stem or a short stem, depending on the purpose, they are needed for. There are a lot of sizes that can be chosen depending upon the amount of liquid that needs to go through them easily and quickly. Funnels are of different sizes 3cm, 5cm, 8cm etc.

Evaporating Dish (China Dish)

An evaporating dish is a small dish made of porcelain used for evaporating and concentrating dilute solutions. It is available in different sizes. It is typically made of glass or metal and has a wide, shallow surface area to allow for evaporation. Evaporating dishes are used for a variety of purposes, including distillation, drying, and concentration of solutions.

Graduated or Measuring cylinders

This is an essential measuring tool for the volume of any liquid. There are a lot of markings, up and down the whole length of the container with special increments. Graduated cylinders are of many sizes. The smaller they are in size or diameter, the more exact or accurate the volume measurements will be. When reviewing the volume from a graduated cylinder, you will consider that the liquid seems to have some indentation.

Measuring cylinders

The liquid around the edges of Graduated Cylinders will be higher than the liquid in the center. This is known as a meniscus. Keep the cylinder at a leveled surface to properly read the volume. They are also available in different sizes 5cm3, 10cm3, 20cm3, 50cm3, 100cm3 and 1000cm3.

Stirring Rod

A stirring Rod or glass stirring rod is used for mixing and stirring different chemicals. it is made up of solid glass  (borosilicate or ) having rounded edges slightly thick and longer than a soda water straw.  Stirring Rods are often 10 to 45 cm long with almost a half-centimeter in diameter. it is also available in the triangular paddle, flat paddle, or round button shape.

Measuring flasks OR Volumetric flasks

A volumetric flask is a round flask with a flat bottom and long neck. Volumetric Flask is used to measure the exact volume of liquids. There is a short line on the neck that hints at how far to fill the flask. Special caps are available that will not let anything in or out through the flask. These are available in different sizes i.e., 100cm3, 250cm3, 500cm3 and 1000 cm3.

Measuring flasks

Just Remember: The temperature affects the volume; therefore always avoid using liquids that will vary in temperature (for example hot water that will cool).

Buret

Burets are often used for the addition of a precise and accurate volume of liquids. with the use of burets, you can measure or determine the volume of liquids up to nearly 0.01 mL. These are normally attached to a ring stand with a clamp.

A buret is also like a glass tube that is open from the top and becomes a narrow pointed opening at the bottom side. Right above the bottom opening; there is a stopcock.

This stopcock can be turned to control the released amount of liquid. There are also certain markings along the length of the buret that indicates the volume of any liquid present in them. A buret is especially used for the extremely accurate addition of liquids.

By slightly adjusting the stopcock, the amount of releasing liquid can be slowed down to a single drop every few seconds.

Burette

Buret is one of the most accurate tools in the laboratory. To determine the added amount of liquid in the solution, write down the readings, and how much is present initially in the buret. Then when you were finished adding liquids, write down how much liquid is left.

Now, Subtract the final amount of liquid from the initial amount and you have the exact volume of liquid that is added.

Forceps

Forcep is derived from the Latin word forcipes used for holding and grasping small objects in laboratories. they are used when things are picked up in bulk or when large fingers are unable to collect little and tiny things. besides this, “forceps” is a very common word in the medical field. in the common world, forces are referred to under different names like pliers, tweezers, clips, stongs, clamps, etc. basically there are two major types of forceps:

  1. Non-disposable forceps
  2. Disposable forceps

Pipettes

There is a large variety of pipettes that are designed to accomplish many specific goals. However, they all are for measuring the exact volume of liquids and then placing liquids into the other containers. Generally available sizes are 10cm3, 20cm3 and 25cm3.Pipette

Thermometer

The temperature of a substance is measured using a thermometer. The temperature in the laboratory is usually measured in units of degrees Celsius (˚C). There are many different types of thermometers, each designed to measure temperature in different ways.

The most common type of thermometer is the mercury thermometer. Mercury is a metal that expands when heated and contracts when cooled. By placing mercury in a glass tube, it is possible to create a thermometer that is very sensitive to temperature changes.

Thermometer

Striker

The Bunsen burner is lightened by the striker. it is used to create sparks or ignite combustible materials. It consists of a metal rod with a pointed end that is struck by a hard object, causing a spark or flame to be produced.

Strikers are often used to ignite Bunsen burners, gas lamps, or other types of flames. In some cases, a striker may be used to create a small explosion, such as when conducting chemical experiments.

Safety is an important consideration when using a striker. Always point the striker away from your body and any flammable materials. Make sure the area is well-ventilated to avoid any potential explosions or fires.

Watch glasses

A watch glass circular convex or concave rounded piece of the glass often used to hold a small amount of solid or liquid, to evaporate a liquid, while being weighed, and for many other purposes. Watch Glasses are also used for different purposes like evaporation.

it can also work as a lid for a beaker to prevent dust from entering the beaker. in the chemistry Lab, two types of Watch glasses are used such as glass watch glasses and plastic watch glasses.

both types have various sizes and varieties in the market. the glass type is more famous than the plastic type. Most glass type is reused and plastic-type are disposable i.e., for one-time use.

Watch glass

Pipet Bulb

Pipet Bulb is used to draw different liquids into the pipet. it is a small, round, glass or rubber bulb that is used to draw liquids into a pipet and is attached to the pipet at the top and has a small opening at the bottom.

To use the pipet bulb, the pipetter first puts the pipet into the liquid. The pipetter then squeezes the bulb, which sucks the liquid into the pipet. The pipetter can then remove the pipet from the liquid and dispense the liquid into another container.

Iron stand

It is used for hanging (thermometer), and clamping/holding (burette, round bottom flask, etc.). An iron stand is an apparatus that is used to support various types of glassware. It is usually made of cast iron or wrought iron.

The stand has a base that is usually square or rectangular, and it has a vertical rod that extends upward from the base. The rod has a crossbar at the top, and the glassware is typically placed on the crossbar. Iron stands are very sturdy and can support a lot of weight, so they are ideal for supporting heavy glassware such as beakers and Erlenmeyer flasks.

Iron stand

Ring Clamp

A ring clamp is an apparatus used to hold test tubes, beakers, and other cylindrical containers in place. It consists of a metal ring that is attached to a base plate, that is used to adjust the size of the ring. The ring clamp is used to hold the container in place while the contents are being mixed or heated.

Wash Bottle

Nowadays polyethylene wash bottles are used in the laboratory for storing distilled water for various operations such as transferring precipitates from a container to the filter paper or washing the precipitates. When the bottle is pressed by hand, water comes out through the jet in the form of a fine stream.

Flat bottomed – Florence flasks, AKA boiling flasks

It is also known as a boiling flask. Florence flask contained a round bottom with a long neck. It is used for holding liquids and can easily be heated and swirled. It can also be capped by glass or rubber stoppers easily. Once again, the safety edict is that this flask never is heated when covered or capped with a stopper. It build-up pressure and can result in an explosion.

Scoopula

A scoopula is a small spoon-like tool that is used to transfer small amounts of powder or liquid from one container to another. It is a common piece of laboratory equipment and can be made from a variety of materials, including plastic, metal, or glass.

Scoopulas are often used to transfer chemicals from one container to another, such as when transferring a powder from a bottle to a beaker. They can also be used to transfer small amounts of liquid, such as when adding a drop of liquid to a test tube.

Erlenmeyer Flasks

The Erlenmeyer flask, also known as a conical flask, is a staple piece of glassware in any laboratory. Its unique shape, with a wide body and narrow neck, makes it ideal for a variety of uses.

One of the most common uses for an Erlenmeyer flask is for mixing and heating chemicals. The narrow neck prevents the contents from spilling, while the wide body allows for a large surface area for heating. The flask can also be placed on a hot plate or Bunsen burner for heating.

Utility Clamp

Utility Clamp resembles a couple of scissors often used to secure glassware to a ring stand. it has a screw in the middle that is used to widen the adjustments between two-prong.  ring stand or retort stand is attached to it. round laboratory glassware is held e.g flasks and beakers etc. with the help of a Utility Clamp. there are three major parts of Utility Clamp:

  • clampdown
  • 2-prong adjust
  • metal rod

Ring Stand

A ring stand helps to support various pieces of equipment such as beakers, flasks, and burets. It typically consists of a metal ring that is mounted on a vertical rod or stand. The ring can be adjusted to different heights, and the rod or stand can be mounted on a base for stability. Ring stands are used in a variety of laboratory settings, and they are an essential piece of equipment for many types of experiments.

Droppers

Droppers are an essential piece of equipment in any laboratory. They are used to transfer small amounts of liquids from one container to another and are available in a variety of sizes and materials. Glass and plastic droppers are the most common, but metal and disposable options are also available.

Droppers come in handy for a variety of tasks in the lab, including adding reagents to test tubes and beakers, transferring small samples for analysis, and measuring out precise amounts of liquid. No matter what the application, choosing the right dropper is essential for accurate and safe results.

Test tube stand

It is made of wood, polyethylene, or steel on which test tubes can be placed in an upright position. Test Tubes are normally held in a test tube rack. Test Tube Racks are specifically designed for this purpose. If these test tubes become risky to touch with bare hands (in a case due to heat or some other reason); test-tube tongs are used to move them.

Test Tube Clamp

On a recent trip to the laboratory, I was able to see and learn about an incredible invention: the test tube clamp. This product is so cool because it can be used as a stand to hold up your test tubes without spilling any liquid. The clamp also has two clamps that can be used as handles for carrying around multiple test tubes at once.

The best part of this invention is that it saves both time and space in labs because scientists no longer need as many lab hands or other furniture such as stands. It’s amazing how one simple tool could make such a huge difference in research!

Clay Triangles

the use of Clay Triangles is seen as very rare but here we can’t miss an opportunity to describe every single opportunity to discuss every apparatus. Clay Triangles are placed on a ring that is attached to a stand that provides support to the funnel, evaporating dish or crucible, etc.

Balance

A balance is an apparatus used to measure the mass of an object. The object to be weighed is placed on one end of the balance, and weights are added to the other end until the balance is in equilibrium. The mass of the object can then be determined by the weights on the balance.

The importance of balance in a laboratory cannot be underestimated. Accurate measurements are essential in any scientific or medical setting, and a balance ensures that these measurements are as precise as possible.

Crucible

The word “crucible” brings to mind images of fiery molten metal, the beating heart of a furnace. The crucible is an instrument used in chemistry laboratories for heating substances until they melt or vaporize. It can also be used for cooling heated material by removing it from the fire and submerging it in water.

But why did this device get its name?

Well, when materials are heated slowly over time, impurities will separate out and rise to the top – like what happens with metals during smelting.

Crucible Tongs

The crucible tongs are a laboratory apparatus that is used to take the hot metal from the furnace into the mold. It’s an essential tool for a chemist, and it can be made using one of two different methods: forging or casting.

Alcohol Burner

alcohol burner is an important part of laboratory equipment. it is used to produce an open flame using alcohol as a burning source.

Syringe

A syringe is an apparatus in the chemistry laboratory used for measuring liquids. It also has many other uses in the medical field that are outside of this blog post’s scope.
