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
Wire Gauze
A metal mesh where you can place various solids on and ignite them with Bunsen Burners. Also used to hold glassware.
26
Evaporating Dish
Heat tolerant container that can hold solids or liquids to melt or evaporate.
27
Wash Bottle
Holds distilled water in order to wash out pieces of laboratory glassware.
28
Gas Bottle
Acts as a vessel to store gasses at above atmospheric pressure.
29
Test Tube Rack
Displays Test Tubes side-by-side to show differences in data and experiments.
30
Crucible and Cover
Used for heating small amounts of material (often metals) at high temperatures, over a Bunsen Burner.
31
24-Well Plate
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
Safety Goggles
Used to protect your eyes from hazardous sources (i.e. corrosive gas, heat, broken glass, etc.)
33
Pipestem Triangle
Used to support a Crucible and Cover over a flame or support a Funnel on a Beaker.
34
Funnel
Guides liquids or powder into a small opening (typically used in conjunction with Filter Paper.)
35
Thermometer
Measure the temperature of a substance in degrees Celsius.
36
Transfer Pipet
Plastic, quantitative pipet that is used to dispense chemicals; often used in place of a Medicine Dropper (usually in mL.)
37
Buret
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
Corks/Stoppers
Prevents the escape of liquid or gas during an experiment (used with Test Tubes and Erlenmeyer Flasks.)
39
Electronic Balance
Used to measure the mass of primary solids and sometimes liquids. Typically have +/-0.01 gram precision.
40
Analytical Balance
A precision measurement tool. Used measure the mass of substances to +/-0.0001 gram precision.
41
Filter Paper
Used to separate solids from liquids when typically when using a Funnel.
