Laboy Glass 100mL Single Neck Round Bottom Boiling Flask Heavy Wall with 14/20 Joint Heating Distillation Reaction Receiving Flask Organic Chemistry Lab Glassware

STANDARD SIZE--- This round bottom flask designed with 14/20 standard taper outer joint,interchangeable,leak-free,comparing to common boiling flask without ground joint, it is convenient,safe,easy-operation in laboratory glassware setup.Capacity of 100mL..
HEAT-RESISTANT DESIGN ---With spherical bottoms,this RBF is more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. Laboy glass flasks are heavy wall designed,made by hand-blowing to ensure uniform wall thickness, 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..
WIDELY USED----The round bottom flask is widely used in organic chemistry,in a distillation or vacuum distillation apparatus ,it’s used a a distillation flask and receiving flask with a glass condenser and some adapters like the 10 way distillation adapter,take-off adapter.
In a reflux process,it’s used as a reaction flask with a reflux condenser.It is also used as a Distilling flask in rotary evaporators..
HIGH QUALITY---Laboy glass condensers are all made of high quality boroslicate glass according to ASTM E438,heavy w....
