Requests for Equipment : Your main function is to provide equipment for experiment and investigations. The first stage in this process is for someone to ask you for certain items. It is not enough to have an oral request; to avoid confusion, a written requisition is vital, and it should be made available to you some time in advance. It is also possible that the same requests will be made year after year or by different people. It can save your effort, therefore, if you keep the written requests together with the list of equipment and materials that you supplied. You should also have a file containing requests that you have not yet fulfilled.
