Q

Medicine Dropper

A

Used to transfer small quantities of liquids.

18
Q

Micropipette

A

Provides precision in drawing and releasing a specific amount of liquid.

19
Q

Striker

A

Used to create a spark which ignites a Bunsen Burner.

20
Q

Bunsen Burner

A

Used for the heating of (nonvolatile) liquids and solids. Connects via a rubber hose to the gas valve, and burns Methane gas. The flame height is adjustable. Ignited with a Striker.

21
Q

Hot Plate

A

An ‘electric plate’ used to heat up various containers such as Beakers and Erlenmeyer Flasks.

22
Q

Ring Stand

A

Used as a structure to hold various Metal Clamps.

23
Q

Utility Clamp

A

Used to support Flasks and Test Tubes when attached to a Ring Stand.

24
Q

Iron Ring

A

Used, in conjunction with a Ring Stand, to support Funnels, Wire Gauze, or Clay Triangles (Pipestem Triangles).

25
Q

Wire Gauze

A

A metal mesh where you can place various solids on and ignite them with Bunsen Burners. Also used to hold glassware.

26
Q

Evaporating Dish

A

Heat tolerant container that can hold solids or liquids to melt or evaporate.

27
Q

Wash Bottle

A

Holds distilled water in order to wash out pieces of laboratory glassware.

28
Q

Gas Bottle

A

Acts as a vessel to store gasses at above atmospheric pressure.

29
Q

Test Tube Rack

A

Displays Test Tubes side-by-side to show differences in data and experiments.

30
Q

Crucible and Cover

A

Used for heating small amounts of material (often metals) at high temperatures, over a Bunsen Burner.

31
Q

24-Well Plate

A

Used to hold small amounts of liquid to compare different trials in specific tests (ex: acid vs. base indicator). Act as miniature Test Tubes.

32
Q

Safety Goggles

A

Used to protect your eyes from hazardous sources (i.e. corrosive gas, heat, broken glass, etc.)

33
Q

Pipestem Triangle

A

Used to support a Crucible and Cover over a flame or support a Funnel on a Beaker.

34
Q

Funnel

A

Guides liquids or powder into a small opening (typically used in conjunction with Filter Paper.)

35
Q

Thermometer

A

Measure the temperature of a substance in degrees Celsius.

36
Q

Transfer Pipet

A

Plastic, quantitative pipet that is used to dispense chemicals; often used in place of a Medicine Dropper (usually in mL.)

37
Q

Buret

A

Used to dispense small amounts of liquids and sometimes gasses with high precision into usually an Erlenmeyer Flask. These are used in titration experiments.

38
Q

Corks/Stoppers

A

Prevents the escape of liquid or gas during an experiment (used with Test Tubes and Erlenmeyer Flasks.)

39
Q

Electronic Balance

A

Used to measure the mass of primary solids and sometimes liquids. Typically have +/-0.01 gram precision.

40
Q

Analytical Balance

A

A precision measurement tool. Used measure the mass of substances to +/-0.0001 gram precision.

41
Q

Filter Paper

A

Used to separate solids from liquids when typically when using a Funnel.
