ISKO® Laboratory Volumetric Flask with Glass Stopper - 5ml Borosilicate Glass Measuring Flask for Chemistry Lab (Class B, 2mm Thickness, 10/19 Socket) - Set of 2 - Perfect for Precise Liquid Measurements in School Labs & Research Experiments

Volumetric flask Crafted from Class 'B' borosilicate glass, this volumetric flask surpasses the precision of beakers or Erlenmeyer flasks in measuring liquid volumes for laboratory experiments. With a 2mm glass thickness and a 14/23 Socket size, this flask ensures accurate measurements and connections. Employ this volumetric flask when it's crucial to know both precisely and accurately the volume of the solution being prepared, making it an indispensable tool in the realm of laboratory science. Volumetric Flask: A volumetric flask is a container specifically designed for accurate measurement of a specified volume of liquid. It typically has a narrow neck with a precise calibration mark, allowing for precise volume control. With Glass Stopper: The flask is equipped with a glass stopper. This stopper serves the purpose of sealing the flask to prevent evaporation or contamination of the liquid inside. It contributes to maintaining the accuracy of the measured volume. 2mm Glass Thickness: The glass used in the flask has a thickness of 2mm. This thickness contributes to the durability and stability of the flask, ensuring it can withstand the conditions of laboratory use.
