Ground-Joint Conical Flask for Repeated Sealing
A conventional conical flask left uncapped is prone to contamination, evaporation and spillage when moved. Fitting this flask with a ground joint and a matching hollow glass stopper gives a tight, reusable seal that a rubber bung or loose cover cannot match, while keeping the flask fully glass-on-glass for chemical compatibility. Lab Glassware's rugged construction is built to withstand the everyday handling of a busy teaching or research bench.
