DESIGN----Round bottom design having spherical bottoms are more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. A cork stand is needed to keep the round bottom flask upright,or heated by the water bath ,oil bath or sand bath.Comparing to the single neck round bottom flask,this 2 neck flask featured an angled neck with standard taper joint as an extra opening..
WIDELY USED---The 2 neck round bottom flask is widely used in the organic chemistry process like distillation, reflux ,extraction,reaction etc.In a distillation apparatus,the 2 neck round bottom flask used as the distillation flask,the straight neck attaches a 3 way distillation adapter or a distillation column(in fractional distillation),the other neck can be used to connect a thermometer adapter ,bleeding tube, or additional funnel..
DIMENSIONS-----This 2 neck round bottom flask has capacity of 2000mL, with 24/40 center joint & 24/40 side joint,attaching any lab glassware apparatus with standard taper joint..
HEAVY WALL ---The 2 neck flask is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstan....
