Jonny-Ringo, first and foremost, loves to read and write. One of his specialities is writing on chemistry. In most labs, you'll encounter the same basic apparatus. Here, you will find a picture and an explanation for how to use each piece of equipment.
The Most Common Laboratory Apparatus and Their Uses Are Listed Below
You will learn about:. The first and foremost rule of any laboratory is to be safe! This may seem obvious, but people often disregard safety protocols for one reason or another, putting themselves and those around them in danger. The best thing you can do is to make sure you follow all safety protocols at all times. Safety goggles are required wear in all chemistry labs. Not wearing them puts you in danger of eye irritation and possibly blindness in the case of an accident.
A small droplet of acid could splash out of the container at any time. Better safe than permanently blinded!
Latex gloves should be used when there is a possibility of corrosive chemicals spilling onto your hands. A beaker is a common container in most labs. It is used for mixing, stirring, and heating chemicals. Most beakers have spouts on their rims to aid in pouring.
They also commonly have lips around their rims and markings to measure the volume they contain, although they are not a precise way to measure liquids. Beakers come in a wide range of sizes.
Because of the lip that runs around the rim, a lid for a beaker does not exist. However, a watch glass discussed below can be used to cover the opening to prevent contamination or splashing. Also known as a conical flask, the Erlenmeyer flask was named after its inventor in It has a narrow neck and expands toward its base.
This allows easy mixing and swirling of the flask without too much risk of spilling. The narrow opening also allows for the use of a rubber or glass stopper. It can easily be clamped to a ring stand discussed below as well as heated or shaken mechanically. An important safety tip here is to never heat this flask while it is capped.It is impossible to imagine a laboratory in a school, medical or scientific organisation without special equipment.
What are the most common laboratory apparatus names and uses? We are sure that some of these things can even be found in your home. Superior gear that is designed for lab scientists, medical workers, students and school pupils can be used for different purposes. Some of the ordinary looking apparatus can magnify, weigh, and measure products and others can help us conduct various tests and essential experiments.
You have probably ever asked yourself, "What is the meaning of 'laboratory apparatus'". It can be any piece of equipment created for use in a workroom to perform tests and conduct studies in the relevant field.
Some pieces of the typical laboratory kit are safe to use, while others require special attention and safety requirements. The common laboratory apparatus are the basic things that are applied everywhere, in physics and chemistry, in medical laboratories and educational institutions.
Each piece has its unique name and is meant to be used in a particular way. What laboratory apparatus is used for heating? Which one is used to measure mass? What are other types of practices designed for this or that piece? The answers are below. Biologists, medical workers, and students love to use microscopes in their projects.
This common piece of equipment is present in almost every laboratory. It is used to magnify anything that is tiny for our eyes to of times its normal size. It can also show the slightest details of a thing, even the invisible cells of plants and skin. What laboratory apparatus is used to measure mass? It is a triple beam balance.
It is not a regular scale used in the shops or at home. It is capable of measuring the accurate weight of chemicals 1, 2, 20 grams, etc.
It is a popular type of laboratory apparatus used in chemistry. Whenever you have to measure a particular amount of liquid and the volume matters a lotyou should choose the special volumetric flask that is designed to hold only a precise amount and no more.
These glass flasks can be of different volume, for example, a millilitre flagon, a millilitre cup, etc. These are famous glass tubes designed to hold liquid and chemicals. Most of these tubes are up to 15 centimetres long. They have no marks. But they are transparent and make it easy to view what you have poured into each one, transport liquids, and sometimes even measure chemicals.
Bunsen burners are the most common equipments that perform multiple functions. It not only heats various chemicals to create a particular reaction, but also works as a sterilizer. Students love this electronic meter. Voltmeters are used in electrical circuits. With their help, it is possible to measure the voltage between 2 points.Many types of apparatus are used for scientific work in the laboratories. Some of the items of common laboratory apparatus used in the laboratory are shown below.
A Bunsen burner is a source of heat or mechanical appliances for which absolute safety is required while using Bunsen Burner. 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.
It is usually made of stainless steel or Aluminium having three supporting legs. Apparatus to be heated is placed on the tripod stand. It is mainly used to support or hold the beakers or flasks during the experiments. A Bunsen burner is placed underneath the tripod stand due to its height. It is the iron wire gauze piece posted with asbestos in the center.
It is placed on the tripod stand so that the flame does not touch the glass apparatus directly, reducing the danger of its breaking. Test Tubes A test tube is a glass tube with one end closed and the other end open.
Common Laboratory Apparatus With Their Uses
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.
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 to easy pouri ng. 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, cm3, cm3 or cm3 are available. It is also known as a Conical Flask. The Erlenmeyer flask was titled inafter 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. 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 nee ds to go through them easily and quickly. Funnels are of different sizes 3cm, 5cm, 8cm etc.Glassware used as laboratory apparatus offers a wide range of containment and transport functions for solutions and other liquids used in laboratories.
Most laboratory glassware is manufactured with borosilicate glass, a particularly durable glass that can safely be used to hold chemicals being heated over a flame and to contain acidic or corrosive chemicals.
All laboratory glassware should be cleaned immediately following use to prevent chemical residue from congealing or hardening. Beakers are glass containers that come in a variety of sizes and can be used for mixing and transporting fluids, heating fluids over an open flame and containing chemicals during a reaction.
While most beakers have graduated volume measurements etched into their glass, the measurements are an approximation that may deviate from the actual volume by five percent, making them unsuitable for use as a precision measurement tool. Glass funnels can be used to guard against spillage when pouring chemicals from one vessel to another, and they can also be fitted with a filter to separate solids from liquids.
Graduated cylinders are tall, narrow containers used for measuring volume. Pipets are used to draw precisely measured amounts of fluid from a receptacle. Volumetric pipets are crafted to draw one specific quantity of a sample, while Mohr pipets have graduations that allow the lab worker to draw varying amounts of a sample.Tagli boschivi
Squeeze bulbs are most often used to draw the fluid into the pipet. Volumetric flasks are used to create precise quantities of solutions. Since Jim Orrill has produced reviews and essays on popular culture for publications including Lemurvision and "Sexis. About the Author. Photo Credits.

You need to know about the common laboratory apparatus and their uses since labs usually contain specialized equipment to help with such work.
Some of the most common kinds of laboratory equipment can magnify, measure, ignite, weigh or hold various substances for a variety of purposes. Microscopes help to magnify things that are too small for the human eye to see well. Volumetric flasks are a kind of glassware that can hold a certain volume of liquid. Bunsen burners help with heating, sterilization or combustion.Chemistry Lab Equipment
Triple beam balances can accurately weigh objects. Test tubes can hold liquids. Voltmeters measure the voltage between two points in an electrical circuit.
Microscopes allow humans to see things that are usually difficult or impossible to see with the naked eye by visually magnifying them.
A List of Chemistry Laboratory Apparatus and Their Uses
Originally invented in the s, the first microscopes were only able to magnify objects to around three or nine times their normal size. Modern microscopes can magnify objects to thousands of times their normal size. They allow humans to see structures, such as the inside of cells, which would otherwise be invisible.
Without the laboratory apparatus and their uses, important breakthroughs, such as the discovery of germs may have never been possible. Compound microscopes are the most common in laboratory environments. Compound microscopes include a base, an illuminator to produce light for better viewing, a stage with clips to hold specimens in place, lenses that provide different levels of magnification, and an eyepiece through which a person can look.
Volumetric flasks are a kind of glassware commonly used in laboratories. These flasks help measure liquids and are more accurate than common measuring cups or flasks. This is because volumetric flasks can hold a precise amount of liquid. For example, a milliliter volumetric flask can only hold milliliters of liquid and no more. Volumetric flasks are popular among chemists since certain reactions require using precise amounts of liquid chemicals.
Bunsen burners are small gas burners that produce a single open flame. They are common in the laboratories of chemists and in school laboratories because they help students observe chemical reactions. The heat from a Bunsen burner can sterilize equipment, heat chemicals to produce specific reactions or facilitate combustion. In a laboratory, you need to know the mass of certain objects, specimens or chemicals with precision. To do this, scientists and medical professionals often use a triple beam balance.
A triple beam balance is a kind of scale that gives an accurate reading of mass using three beamseach marked with different gram increments. The smallest beam is the most precise, using increments of 1 to 10 grams. The middle beam uses increments of 10 grams, while the largest uses increments of grams. Weights attached to each beam can move back and forth.Learn more about Scribd Membership Home.Alex smith hat films instagram
