Intro to Lab Equipment

!

Balance (scale) , also known as a Triple Beam Scale

is used to weigh the mass of materials using three

beams which eachhold a different weight.

A watch glass is a circular, slightly piece of glass

used in chemistryas a surface to evaporate

a liquid, or as a cover for a beaker.

A dropper glass tube with a hollow rubber bulb at one

end and a small opening at the other, for drawing in

a liquid and expelling it in drops; medicine dropper.

 

 

Wash Bottle is a flexible squeeze-bottle with delivery tube, or a bottle

having two tubes through the cork, so arranged that blowing into

one will force a stream of liquid from the other; used in washing

chemical materials. 2. a bottle containing some washing fluid,

through which gases are passed for the purpose

of freeing them from impurities.

 

Test Tubeis a tube of thin glass closed at one end, used for

various procedures in chemistry and for

the growth of bacterial or viral cultures.

The test tube holder is the holder made out of wire in your lab

drawer. You hold it in your hand and squeeze on the handles

to open the other end, into which you then insert a test tube.

This small piece of equipment does nothing except hold test tubes.

 

 

The clay triangle is used to hold a crucible while the crucible is heated.

 

 

 

 

Pipets are used make precise measurements and to

transfer liquids.

 

Erlenmeyer flasks are used to mix, store, or heat solutions or other liquids.

 

A graduated cylinder is used for more precise volume

measurements.

A stirring rod is used to mix solutions and other substances.

A spatula can be used to remove a sample from the weighing bottle

and the sample placed directly into the flask. 

An iron ring clamp is an iron ring with a clamp that holds glassware

such as a funnel or other objects, such as a wire gauze

or clay triangle for heating with a bunsen burner.

Evaporation, in a technical sense, denotes the conversion of a

liquid into a vapor for the purpose of separating it from another

liquid of higher boiling point. 

 

A rubber stopper is used to seal contents into a container.

 

Test tube racks are used to hold test tubes during experiments or storage.  

 

Crucible tongs are used for picking up hot or

otherwise hazardous material containing vessels.

Utility Clamp is used to secure glassware and other equipment.

A buret is used for delivering the second reactant to the

flask and an indicator or pH Meter is used to

detect the endpoint of the reaction.

A beaker is used for just about anything in a lab.

A Florence flask is used to heat liquids that need to be

heated evenly. 

Goggles are used to protect your eyes in the lab area.

Forceps are used to grasp/hold small items, they are often

used in dissection. 

 

 When placed between glassware and a heat source,

wire gauze allows for more even and gradual heating of glassware

 

Ringstand used to hold glassware in

place during an experimental procedure

Evaporating dish isused to heat

and evaporate liquids

 A pestle is a tool used to crush, mash or grind materials in a mortar

 

 Test tube brush is used to clean small diameter

 test tubes.

 

Crucibles are used to heat substances in the

chemistry lab. 

 

 

Buret Clamps hold valuable laboratory so procedures are

always safely done.

 

Bunsen Burners are used to heat substances in the lab.

 

Beaker Tongs are used to grasp/hold items

like test tubes and beakers. 

A volumetric flask is used to measure

very precisely one specific volume of liquid.
