Frequently Asked Questions

What is a 100 mL volumetric flask used for?

A 100 mL volumetric flask is used to prepare solutions of precise concentration by dissolving a measured amount of solute and diluting to the exact 100 mL graduation mark. Analytical chemists, pharmaceutical researchers, and clinical technicians rely on volumetric flasks for calibration standards, buffer preparation, and serial dilutions.

What is the difference between Class A and Class B volumetric flasks?

Class A volumetric flasks have tighter calibration tolerances per ASTM E288 and include individual or batch calibration certificates for traceability. Class B flasks have wider tolerances and are suitable for educational use and non-critical applications. Both classes are manufactured from the same 3.3 borosilicate glass.

What volumetric flask sizes does LabSupplies.com carry?

LabSupplies.com stocks Globe Scientific volumetric flasks from 1 mL to 2000 mL in Class A and Class B calibrations. Narrow mouth and wide mouth configurations are available, along with polypropylene options for break-resistant applications.
