• Premium Quality: Made of high-quality borosilicate glass, heavy glass wall, durable and reusable.
• Standard Size: The round-bottom flask features the 24/40 standard taper outer joint, interchangeable and leak-free. The capacity of 250ml.
• Heat-Resistant: With the round bottom, the boiling flask is more resistant to breaking under vacuum, as a sphere can evenly distribute stress across its surface. Heavy glass wall, made by hand-blowing to ensure even wall thickness, made of high-quality borosilicate glass and annealed at 800 degrees Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in chemistry processes like heating and cooling.
• Wide Application: The round bottom flask is widely used in organic chemistry, in distillation, or vacuum distillation apparatus.
