Common use of LABORATORY NOTEBOOK Clause in Contracts

LABORATORY NOTEBOOK. The lab notebook is used as a legal document detailing everything that occurred in the lab. You need to use it in lab to keep track of what you have done and what you have to do. It is therefore very important to prepare your notebook well and take meticulous notes. All writing in the notebook should be in non-erasing black ballpoint pen. Title your lab and fill out the top of the notebook page. Include any objectives. If you are doing a reaction, write the balanced reaction and underneath the reaction write down any pertinent information (such as bp, fw, expected moles, expected grams, density, volume). Leave space for actual moles and actual grams. In fact, write down pertinent information for all chemicals for every lab Write down a concise but complete outline of the procedure to be followed. Remember to leave room to add information or make changes. As you are preparing your notebook, remember to leave room to record amounts that you actually use. Make a drawing of the apparatus you will use. Your notebook will contain all of your calculations, observations and measurements. Record every measurement, observation, mistake and reasoning. Example: “We started over because we dropped the reaction flask.” Label each entry in a meaningful manner that indicates the part of the experiment that corresponds to the entry. Because a lab notebook is a working document, it will most likely contain errors. Errors should have a single line drawn through them. There should be no erasures or white out used in the lab notebook. At the end of the lab period, sign and date each page and then let your instructor verify & initial your notebook.
