About this item DESIGN----This three neck flask designed with a round bottom and angled necks which allows to attach three lab glassware components for apparatus( simple ,steam ,fractional ,azeotropic ).Round bottom design having spherical bottoms are more resistance to fracturing under vacuum, as a sphere more evenly distributes stress across its surface.and allows more uniform heating or boiling of a liquid. WIDELY USED ---Round-bottom flasks are often used to contain reactions for reflux set-ups and laboratory-scale synthesis.It also can be used as a flasks and receiving flasks for the distillate. For example, in a Grignard Reaction,a 3 neck flask will be used a flask under a heating mantle, the center neck attaches a PTFE adapter for a magnetic stir shaft, the left angled neck attaches a pressure equalizing.The wrong neck attaches a liebig or west condenser. DIMENSIONS-----This durable round bottom flasks with 3 necks, one center and two angled,with 24/40 standard taper joints on the necks accommodating lab apparatus for multi purpose. It features heavy wall spherical body and 2000mL capacity.Comparing to the single neck or twin neck flask,the 3 neck flasks have one more jointed neck for extra function,when it is not needed,the extra necks can be stopped by penny head glass stoppers. HEAVY WALL ---The 3 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 withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable. 100% 45 DAY MONEY BACK GUARANTEE If you are not satisfied for any reason, simply return for a full refund, no questions asked.
