  • HEAVY WALL ---The 2 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.
This 2 neck round bottom flask is designed with spherical bottom to resist to fracturing under vacuum or heating,which need to sit on a cork stand to keep upstraight or be heated under a fire or heating mantle.
The center and angled side neck have the same or different joints for option.
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.
