Borosilicate Glass Single Neck Round Bottom Flask 5-20000mL

The Single Neck Round Bottom Flask is a commonly used heating and reaction vessel in chemical experiments, with a wide range of applications. Heating can be carried out, usually by placing asbestos mesh on it and using it in conjunction with clamping instruments such as iron frames. Single Neck Round Bottom Flask is a carefully selected thick walled high borosilicate flask. All flasks below 1000ML are hand blown, while those above 2000ML are carefully selected large furnace materials with uniform thickness and durability. Good heat conduction, ultrasonic cleaning is not easy to break, the frosted pipe mouth is smooth and delicate, and the seal fits well.
