1. LANGUAGE OF THE LAB Using Laboratory Tools Properly!

2. STORAGE

3. BEAKERS Used for containing liquids. Scale printed on the glass is just an estimation---not accurate, and not used for measuring out precise amounts of liquids! Can be heated.

4. Used for storing liquids. Narrow neck allows for easy storage, it can be closed using either a cork or parafilm! NOT used for measuring! The amounts printed on the flask is highly inaccurate and only allows for the estimation of amounts! ERLENMEYER FLASKS

5. Used to contain, mix, and store small amounts of liquids Not used for measurement of liquids Not accurate TEST TUBES

6. Used to store and centrifuge very small amounts of liquids. Not used for measurement. MICRO-CENTRIFUGE TUBES

7. MEASURMENT

8. Used for Measuring liquid amounts with an accuracy of a tenth of a mL. Good for relatively large amounts of liquids when precise accuracy is not needed! GRADUATED CYLINDER

9. Allows for precise and accurate dispensing of solutions. Accurate to 1/100 th of a mL Used in titrations to evaluate the PH of an unknown solution. BURET

10. Micropipettes—used to precisely dispense small amounts (microliters) of liquid. Pipettes—used to precisely dispense milliliters of a solution. Disposable Pipettes—used for transferring liquid, not accurate! PIPETTES

11. TOOLS

12. Used to mix small amounts of liquid Must be balanced just like the large version used in chemistry MICRO-CENTRIFUGE

13. Hot Plate—Used to heat up solutions. Hard to maintain a specific temperature! Hot Water Bath—Used to heat up solutions at a precise and constant temperature! HEATING

14. Power Source used to run a consistent and known amount of voltage through a electrophoresis cell Gel Electrophoresis Cell—is used to separate molecules based on charge, size, and shape POWER SOURCE AND GEL ELECTROPHORESIS CELLS
