PYREX® VISTA™ 100mL Class B Volumetric Flask with Polyethylene Snap Cap – 70581-100

The PYREX® VISTA™ 100mL Class B Volumetric Flask is a reusable laboratory glass instrument designed for preparing standard solutions, sample dilution, chemical analysis, and routine volumetric measurements. Manufactured by Corning, the flask features a long neck with a permanent calibration line, clear glass construction, and a blue polyethylene snap cap for convenient closure. Its Class B accuracy makes it suitable for general laboratory applications where Class A precision is not required. Ideal for pharmaceutical laboratories, medical laboratories, chemical testing facilities, research institutions, educational laboratories, and quality control departments.
