Description
Round Bottom Flasks, Single Neck, Borosilicate Glass 3.3 – Glassco (50 mL to 5000 mL)
Glassco single-neck round bottom flasks are precision-manufactured from borosilicate glass 3.3, offering excellent thermal resistance, chemical durability, and dimensional accuracy. The spherical shape ensures uniform heat distribution, making these flasks ideal for boiling, refluxing, and controlled chemical reactions.
Ground glass joints provide leak-tight connections with condensers, adapters, and other laboratory apparatus. These flasks are widely used in academic, pharmaceutical, and industrial laboratories for synthesis, heating, and distillation processes.
