Equipment & Safety Part 1

This is used to hold and dry test tubes.

• Test Tube Rack

• Digital Balance

• Weigh Boat

• Volumetric Flask

This is used to hold small amounts of pre-measured substances.

• Scoopula

• Test Tubes

• Weigh Boat

• Pipette

This is used to measure how much heat energy is in an object.

• Thermometer

• Meter Stick

• Microscope

• Digital Balance

A digital balance is used to

• determine the mass of a larger, heavier objects mass

• weigh or transfer chemicals (usually dry)

• magnify very small items for easier viewing

• determine a smaller, lighter objects mass

A triple beam balance is used to

• determine the mass of a larger, heavier objects mass

• weigh or transfer chemicals (usually dry)

• magnify very small items for easier viewing

• determine a smaller, lighter objects mass

What tool is used for transferring dry chemicals?

(a)  

What tool is used to transfer liquid from one container to another (increments are very small - usually .25 mL per increment)?

(a)  

A _________________ is used to measure large volumes of liquid (increments are larger than a graduated cylinder - usually 25-50 mL per increment).

• Beaker

• Graduated Cylinder

• Erlenmeyer Flask

• Volumetric Flask

A ___________________ is used for making liquid solutions of precise volumes.

• Beaker

• Graduated Cylinder

• Erlenmeyer Flask

• Volumetric Flask

A _______________________ is used to measure volume of liquids - more precise than a beaker (increments are smaller than a beaker - usually 1 mL per increment).
