PYREX Volumetric Flask 25 ml with Plastic Snap Cap is the perfect glassware for lab use. The strength of these flasks has been increased appreciably through machine-blown bodies, which are sealed with heavy-beaded, heavy-tubing necks, tooled for snap cap fit. The graduation line is sharp and permanent; large white block letters make the inscription easy to read. The 25 mL size is test-tube-shaped.

A Pyrex Volumetric Flask 25 ml is a laboratory glassware item designed for the precise measurement of liquid volumes, particularly useful in analytical chemistry and other scientific applications. This volumetric flask is made from borosilicate glass, a type of glass known for its resistance to chemical reactions, heat, and thermal shock, making it durable and reliable in various laboratory environments.

Key Features of Pyrex Volumetric Flask 25 ml:

• Material: Borosilicate glass (Pyrex), providing high resistance to thermal and chemical stresses.
• Capacity: 25 ml, calibrated to contain an exact volume of liquid when filled to the single graduation line.
• Calibration: The flask features a precise, etched calibration mark on the narrow neck, which indicates the accurate volume when the liquid level aligns with the line.
• Stopper: The flask usually comes with a glass or plastic stopper, preventing evaporation and contamination of the liquid inside.
• Shape: It has a flat, wide base for stability and a long, narrow neck to minimize spillage and evaporation during use.

Uses:

• Standard Solutions Preparation: Commonly used for preparing exact concentrations of solutions, particularly when working with small amounts of liquid.
• Titrations: Employed in titration processes where accurate volume measurements are required for chemical reactions.
• Dilution of Solutions: The 25 ml capacity makes it suitable for diluting concentrated solutions to achieve desired concentrations.
