 ===== Storing liquids inside a box =====
-Larger amounts of liquids like solvents are best stored inside laboratory screw-top bottles ({{ref>bottles}}).
+Larger amounts of liquids, such as solvents, are best stored in laboratory screw-top bottles ({{ref>bottles}}). Proven suitable sizes are 500 mL, 250 mL, and 100 mL.

+Note that there are different types of screw caps ({{ref>caps}}). Some may not have a gasket ({{ref>without}}). These are unsuitable for a glovebox because they do not seal properly. Therefore, they constantly release small amounts of solvent fumes into the box atmosphere, which saturates the solvent filter prematurely and damages the system. Only use screw caps with a rubber gasket protected by a thin layer of PTFE foil ({{ref>with}}).
