laboratory glove box and its associated devices. General Information: A glove box, also called a dry box, is a confined gas tight space allowing the manipulation of chemicals under an inert atmosphere. To some extent a glove box can be regarded as a substitute for conventional inert-gas Schlenk techniques employed on the laboratory bench.

Glovebox Technique - an overview | ScienceDirect Topics

A typical copolymerization reaction is given below (Table 2, run 3). In a glove box, 15 mL of toluene, 1.736 g (21 mmol) of 1-hexene were mixed together in a 100 mL two-necked round-bottom glass flask with a stirring bar. The flask was taken outside and attached to a Schlenk line, a well-purged ethylene line, and a mercury-sealed stopper.
