Flat bottom flasks for heated chemical reactions or distillations are offered at Avantor. Borosilicate glass models feature heavy wall construction in an array of capacities. Select a short or long neck flask to suit your purpose. A reinforced standard taper (24/40) outer joint is offered for most models, however some options do feature other joint sizes. Some flat bottom flasks conform to ASTM requirements. Purchase items individually or in packs.
