Nathaniel Loue P. Ferandez June 16 2015BSMEJune 17, 2015Naming apparatus and their uses in Chemistry.

ObjectivesTo identify different apparatus found in Chemical laboratory.To know which apparatus is suited for certain activity.To mitigate ignorance while conducting experimentations.To know the uses of chemical apparatus.To know the locations where you can obtain them.

AbstractThis paper will elaborate chemical apparatus and their uses which are shown in the data table. The data table consists the information needed to provide proper description of the apparatus and basic knowledge of when and how to use it. A picture is also provided to show what the object looks like, also there is a description for when a picture may fail to deliver unto the readers what the object may be. Question and analysis is also provided to answer similar questions regarding the topic for the reader to fully comprehend the information given. I have also given recommendations on how to take care of the apparatus and where to buy on in case you need to replace the one you broke or in case you dont have one and you need it. Bibliography may also be found in the paper for those interested in going to the source of this information.

Data TableApparatus`UsesDescription

Beaker

Abeakeris a simple container for stirring, mixing and heating liquids commonly used in many laboratoriesBeakers are generally cylindricalin 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 onemilliliterup to severalliters.

Erlenmeyer flaskThe tapered sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations.It features a flat bottom, a conical body, and a cylindrical neck.

Florence flask

It is used as a container to hold liquids.. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use.. A Florence flask has a round body with a flat bottom and a single long neck. They are often made ofborosilicate glassfor heat and chemical resistance. Traditional Florence flasks typically do not have aground glass jointon their rather longer necks, but typically has a slight lip or flange around the tip of the neck. A common volume for a Florence flask is 1litre.

Graduated cylinderA graduated cylinder is used to measure the volume of a liquid.It has a narrow cylindrical shape. Each marked line on the graduated cylindrical represents the amount of liquid that has been measured. Large graduated cylinders are usually made up ofpolypropylenefor its excellent chemical resistance orpolymethylpentenefor its transparency, making them lighter and lessfragilethan using aglassas a material.

Gas collecting bottleUsed when large volumes of gas are produced and must be collected by displacement of waterA flat bottomed bottle with a cylindrical body and narrow neck

Test tubes

Test tubes are widely used bychemiststo hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents. a common piece oflaboratory glasswareconsisting of a finger-like length ofglassor clearplastictubing, open at the top, usually with a rounded U-shaped bottom. A test tube has either a flat bottom, a round bottom, or a conical bottom. Some test tubes are made to accept aground glass stopperor ascrew cap.

Ignition tubesIt is alaboratory tubeused much in the same way as aboiling tube except not being as large and thick-walled.a heavy-walled test tube of hard glass for examining the behavior of heated substances

Test tube holder

Used for holding hot test tubes.Brass wire, with formed loop on either side of handle providing finger grip, has self-closing jaws that take tubes 6 mm to 32 mm diameter.

Test tube brushesIt is used to clean tubes and graduated cylinder.A small metal stick with brush attached to them

Test tube racksUsed for holding and organizing test tubes on the laboratory counter.Wooden rack with holds to hold test tubes, has a concave bottom to hold the test tubes in place

Rubber stoppersUsed to close containers to avoid spillage or contaminationA cylindrical shaped rubber.

Spot platesUsed when we want to perform many small scale reactions at one time.Egg holder shaped ceramic plate

Watch glassUsed to hold a small amount of solid, such as the react product of reaction.A concave glass

Glass stir rodUsed to manually stir solutions. It can also be used to transfer a single drop of a solution.Glass tubes

Medicine droppertransport a measured volume of liquid,Tube with a presser in the end to release air then make a vacuum

Litmus paperBlue litmus paper is used to identify acids and red litmus paper is used to identify bases.awater solublemixture of differentdyesextractedfromlichens. It is often absorbed ontofilter paperto produce one of the oldest forms ofpH indicator, used to test materials for acidity.

ForcepsUsed to pick up small objects.Tweezer like item that has a thin tip

Funnel

Used to aid in the transfer of liquid from one vessel to another.Made of glass and has a wide opening and a narrow ending.

Mohr pipet

Measures and delivers exact volumes of liquids.A narrow tube with measuring lines.

Wash bottleDelivers a wash solution to a specific area.Plastic bottles with a curved narrow neck

Weighing boatUsed to weigh solids that will be transferred to another vessel.Boat shaped plastic.

SpatulasUsed to dispense solid chemicals from their containers.Made of metal which has tips shaped like shovels.

Beaker tongsUsed to move beakers containing hot liquids.Silicone-tipped locking tongs designed to withstand temperatures up to 500 degrees Fahrenheit

Bunsen burnerUsed for heating nonvolatile liquids and solids.A Bunsen burner withneedle valve. The hose barb for the gas tube is on the left and the needle valve for gas flow adjustment is on the opposite side. The air inlet on this particular model is adjusted by rotating the barrel, thus opening or closing the vertical baffles at the base.

Evaporating dishUsed for heating of stable solid compounds and elements.Most are made ofporcelainorborosilicate glass. Shallow glass evaporating dishes are commonly termed "watch glasses", since they resemble the front window of apocket watch

Crucible

Are used for heating certain solids particularly metals, to very high temperatures.Cup shaped ceramic container.

Clay triangleUsed as a support for porcelain crucibles when being heated over a Bunsen burner.A wire with clays attached to the

Crucible tongUsed to pick up other hot objects. Not to be used for picking up beakers.Metal brass

Glass platesUsed to provide a surface for semi-micro scales experiments such as drop reactions and testing of acids and bases.Ash tray shaped tampered glass

Triangular fileUsed to primarily cut glass rod.A metal with the texture of a nail file but shaped triangularly

Ringstands Used as a backbone for carrying the parts for burning.Metal rod with a base below to avoid swaying and to stabilize the platform

Iron ringsUsed to provide a stable, elevated platform for the reactionRing shaped iron with clamps attached to the end to be able to connect with the ring stand

Utility clampsUsed to secure test tubes, distillation columns, and burets to the ringstand.Clamp with a plastic tip with grip to hold tubes when heating

Double buret clampsUsed to buret long graduated tubes in titration.Double ended metal clamp

Wire gauzeProvides a place to stand a beaker.Gauzeis a thin,translucentfabricwith alooseopenweave

Pressed fiber padProvides a surface for hot beakers so that the beaker does not come in contact with a cold countertop and shatter.Made of compressed heat resistant synthetic fibers.

StrikersUsed to light Bunsen burnersMetal wire that has a flint sparker in the end

Conclusion/sources of errorFirst source of error is my lack of experience dealing with these objects.Second source of error is inconsistent definition found on the internet, so I have only inserted the data from a website I trust.Third source of error was my incapability to segregate the items alphabetically because I segregated them in a way which they were relevant to the previous item.

Question and analysisWhat types of apparatus can be found inside a chemical laboratory?Most apparatus found inside a chemical laboratory are used to hold and measure liquidAre the apparatus fragile? If so should it be handled carefully?Most of the apparatus are fragile as they are made of glass. These apparatus should be handled very carefully as they hold dangerous chemicals such as hydrochloric acid (HCL)Can certain apparatus be used for another use?They can be used, but it is not advisable as they may not give the same results if used correctly.Can these apparatus be found in other laboratories?`Yes, but only wet laboratories (laboratories dealing with chemical substances )Where can we buy these items if we need them?I have listed them belowRecommendationI would recommend the following places if you are interested in buying chemical apparatus.Tokyo Rikakikai12th floor, 88 corperate center, 141 Valero street, corner Sedeno Street, Salcedo village, Makati City, 1227, Metro Manila.
