Borosilicate Round Bottom Flask (500 ML)

Features:

• Made of heat-resistant borosilicate glass.
• Size of round bottom flask is 500 ml.
• Its shape is more resistant to fracturing under vacuum, as a sphere distributes stress across its surface.
• An additional neck allows a dropping funnel to be attached so that reactants drip slowly.

Uses:

• For heating or boiling of liquid.
• Used in distillation.
• Contain chemical reactions.
• Distilling flask in rotatory evaporators.
• Storage of the culture media.
• Preparation of the gas-phase standards for flasks fitted with septa (volumetric calibration is required).

Precautions:

• Wash the round bottom flask before use.
• Before using, examine it carefully – it should not be scratched, cracked, chipped, or etched.
• If the flask contains any defect, remove it from the laboratory as it can seriously weaken the mechanical strength of glass and cause to break while use.
• Never hold it from the neck, always support from the base and sides.
• When stirring solutions in the flask, avoid using stirring rods with sharp ends.
• Always heat gently and gradually to avoid sudden temperature changes as it can cause glass to break due to thermal stock.
