PYREX® VISTA™ 10mL Class B Volumetric Flask with Polyethylene Snap Cap – 70581-10

The PYREX® VISTA™ 10mL Class B Volumetric Flask is an economical laboratory glass instrument designed for preparing solutions, diluting samples, and measuring precise fixed liquid volumes during routine laboratory procedures. Manufactured by Corning, the flask features a long neck with a permanent calibration mark, a flat-bottom glass body, and a blue polyethylene snap cap for convenient closure. Its Class B accuracy makes it suitable for routine laboratory applications where Class A precision is not required. Ideal for pharmaceutical laboratories, chemical testing facilities, diagnostic laboratories, research institutions, educational laboratories, and quality control departments.
