    It is often needed to transfer chemicals from one container to another in organic chemistry laboratories. The proper approach to take depends on the nature of what needs to be transferred.

    • 1.3A: Transferring Methods - Solids
      A solid can be dispensed from its reagent jar directly into a vessel or onto a weighing boat or creased piece of paper. If a solid is to be transferred into a vessel containing a narrow mouth (such as a round bottomed flask), a "powder funnel" or wide-mouth funnel can be used. Alternatively, the solid can be nudged off a creased piece of paper in portions using a spatula.
    • 1.3B: Transferring Methods - Liquids
      When transferring liquids with volumes greater than 5 mL, they can be poured directly into vessels. Graduated cylinders and beakers have an indentation in their mouth, so they can be poured controllably as long as the two pieces of glass touch one another.
    • 1.3C: Transferring Methods - Inert Atmospheric Methods
      Meticulously dry or oxygen-free conditions are sometimes necessary when using reagents that react with water or oxygen in the air. To safely and effectively use these reagents, glassware should be oven or flame dried, then the air displaced with a dry, inert gas (often nitrogen or argon). This creates an "inert atmosphere" inside an apparatus, one that will not react with the reagents. Inert gases can be delivered to a flask through gas lines and a gas manifold.
