Four-Neck Angled Rb Boiling Flask 250ml With 24/40 Center& Side Joints
Special Price $45.55 Regular Price $70.50
- DESIGN----This four neck distilling flask designed with a round bottom and angled necks which allows to attach three lab glassware components for distillation apparatus( simple distillation,steam distillation,fractional distillation,azeotropic distillation).Round bottom design having spherical bottoms are more resistant 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 chemical reactions for reflux set-ups and laboratory-scale synthesis.It also can be used as a distilling flasks and receiving flasks for the distillate. For example, in a Grignard Reaction,a 4 neck flask will be used a distillation 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 4 necks,with 24/40 standard taper joints on the necks accommodating lab apparatus for multi purpose. It features heavy wall spherical body and 250mL capacity.Comparing to the single neck or twin neck flask,the 4 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 4 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.

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 4 neck flask featured extra angled necks with standard taper joints as openings.
WIDELY USED ---Round-bottom flasks are often used to contain chemical reactions especially for reflux set-ups and laboratory-scale synthesis.It also can be used as a distilling flasks and receiving flasks for the distillate.This triple neck flask has standard taper joints on the 4 necks,which allows 4 entries for 4 glassware parts,for example, in a Grignard Reaction,a 4 neck flask will be used a distillation 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 4 necks, one center and two angled,with standard taper joints on the necks accommodating lab apparatus for multi purpose. It features heavy wall spherical body.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.
