Laboy Glass 50mL Single Neck Round Bottom Boiling Features
-
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 50mL.Pack of 6pcs.
-
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 9 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 wall design,durable and reusable.The ground joints are precisely grounded according to US standard.

About Laboy Glass 50mL Single Neck Round Bottom Boiling
Round-bottom flasks (also called round-bottomed flasks, Flasks, round bottom, or RB Flasks)having spherical bottoms are more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. Because of the spherical bottom, cork rings are needed to keep the round bottom flasks upright. When in use, round-bottom flasks are commonly held at the neck by flask clamps on a stand. The flasks are usually used in heating or boiling a liquid, in distillation as distilling flasks and receiving flasks for the distillate, used as the distilling flasks in rotary evaporators. 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.
