Biological Abbreviations GuideSheet and Formulas learly label all containers with content name. Write out the complete chemical and/or biological name or use abbreviations (useful for small containers). If abbreviations are used, display this guide sheet prominently at C several locations in each lab. Extend the list with lab-specific abbreviations, as necessary.
