1. Place a desiccant (like anhydrous CaCl) in the bottom, with a perforated plate above it.
2. Place your samples on the plate.
3. Seal the lid by sliding it on carefully (sometimes "hugging" the desiccator for stability).
4. Connect a vacuum pump to the stopcock and draw air out; the PTFE plug allows for vacuum creation, sealing, and release.
