Product Description

By entering your model number, you can make sure that this fits.

STANDARD SIZE--- This round bottom flask is designed with a 45/50 standard taper outer joint, which is interchangeable and leak-free. When compared to a common boiling flask without a ground joint, it is more convenient, safe, and easy to use in laboratory glassware. It has a 500mL capacity.

HEAT-RESISTANT DESIGN ---This RBF is more resistant to fracturing under vacuum thanks to its spherical bottoms, which evenly distribute stress across its surface. Laboy glass flasks have a thick wall design and are hand-blown to ensure uniform wall thickness. They are made of high-quality borosilicate glass and annealed at 800 degrees Celsius. They can be heated directly in an open flame and can withstand typical laboratory thermal variations in chemistry processes such as heating and cooling.

WIDELY USED----The round bottom flask is widely used in organic chemistry. It is used as a distillation flask and receiving flask with a glass condenser and some adapters such as the 14 way distillation adapter and the take-off adapter in a distillation or vacuum distillation apparatus. It is also used as a reaction flask with a reflux condenser in a reflux process. It's also used in rotary evaporators as a distilling flask.

HIGH QUALITY---All Laboy glass condensers are made of high-quality boroslicate glass that meets ASTM E438, have a heavy wall design, are durable, and can be reused. The ground joints are precisely grounded in accordance with US specifications.

Questions & Answers

Is borosilicate glass alkali resistant?

I'm fairly certain that's the case. It's even where nuclear materials are stored.
