PYREX Volumetric Flask 50 ml With Plastic Snap Cap. The strength of these flasks has been increased appreciably through machine-blown bodies, which are sealed 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 50 mL size is test-tube-shaped.

A Pyrex Volumetric Flask 50 ml is a laboratory glassware item designed for the precise measurement and preparation of liquid volumes, particularly in chemical, biological, and pharmaceutical applications. Made from high-quality borosilicate glass, this flask offers excellent thermal resistance and chemical durability, making it suitable for use in a wide range of laboratory environments.

Key Features of Volumetric Flask 50 ml:

• Material: Borosilicate glass (Pyrex), renowned for its resistance to heat, thermal shock, and chemical reactions, ensuring durability in various lab conditions.
• Capacity: 50 ml, calibrated to contain an exact volume when filled to the graduation mark.
• Calibration: A single etched line on the narrow neck indicates the exact 50 ml volume, ensuring high precision for accurate liquid measurements.
• Stopper: The flask typically comes with a glass or plastic stopper, which helps to prevent contamination and evaporation, maintaining the integrity of the liquid inside.
• Shape: It has a wide, flat base for stability and a long, narrow neck that helps reduce the risk of spills and minimizes evaporation during handling.
