How to Keep an Organic Laboratory Notebook

How To Keep an Organic Laboratory Notebook 

 The laboratory notebook is an essential tool all science related careers.  The lab notebook is the primary record of experiments.  It is vital to learn how to keep a properly organized notebook for this course and your future research endeavors.  Organic notebooks are different than general chemistry notebooks. 

Every instructor, class and discipline has unique lab notebook keeping rules.  This guide contains the basic lab notebook rules for this course:

  • Notebook must be a bound composition notebook (Graph paper is preferred but not required)
  • Always write in pen (preferred black or blue) (Gel pens are less likely to fade and/or smudging if solvent is spilled on the book)
  • Never erase or use correction fluid or tape (Draw a line through the mistake and write it again: Allows you and others to see your mistakes later      (it might not have been correct),  If an entire section needs to be rewritten, put an “X” over it and write it again)

  • Clearly label the front of your notebook

Student Name

Organic Chemistry Laboratory Notebook

Gwinnett Technical College

Start Date: ______             End Date: _____

  •  Each page should be numbered at the top
  • Right hand (odd numbered) pages are used for writing objective (purpose), special instructions/warnings for chemicals, pre-lab procedures and conclusions
  • Left hand (even numbered) pages are used for diagrams, physical data, observations, modifications, calculations and data recording

  •  Reserve two pages in the front of the book for the Table of Contents.

Table of Contents

Course: Organic Chemistry I

Experiment #

Experiment Title

Page Number

Date of Experiment

 

 

 

 

 

 

 

 

  •  Begin your first experiment on page 5 (remember the first two pages are for the table of contents)

Page 5

 

Experiment Date: Date the lab was conducted

Diagram of lab apparatus: (labeling all glassware)

 

 

Experiment Title: Describes lab content

Physical Data of all chemicals: (use the CRC Handbook to note density, concentration, molar mass, solubility, hazards, precautions, etc.)

 

 

Objective/Purpose:

Observations

 

 

 

Modifications to procedure:

Balanced Equation/ Reaction Mechanism (calculate the theoretical yield of the reaction)

 

 

Calculations:

Procedures/Experimentation: detailed protocol on how to conduct the experiment **DO NOT COPY THE LAB HANDOUT WORD FOR WORD. **

1) Write the procedures in your own words, with as much detail as required for you to understand the steps you will do in the lab. 

2) It is helpful to write it in a stepwise manner, so you can keep track of which step you are on during lab.

3) If changes are made to any step, record the change on the left hand page.

 

 

 

Results: clearly state key results, % Yield, spectra analysis, etc.

 

 

 

Conclusions: Sum up the experiment.  Give a brief explanation of results.

 

  • This notebook will be used to write the formal laboratory report, so include as much detail as possible.

 

*NOTE: YOUR LAB NOTEBOOK WILL NOT ALWAYS BE NEAT!*
