Weighing Bottles
Weighing bottles are convenient for drying and storing solids. Two common varieties of these handy tools are shown in Figure 1.1. The ground-glass portion of the cap-style bottle shown on the left is on the outside and does not come into contact with the contents.

This design eliminates the possibility of some of the sample becoming trapped on the ground-glass surface and subsequently being lost. Ruggedness is a principal advantage of using plastic weighing bottles rather than glass, but plastic abrades easily and is not as easily cleaned as glass.
