These flasks are designed for the determination of phenols in essential oils, light oils, middle oils and creosote oils and for the determination of aldehydes and ketones. They are also used for other applications where a lighter fraction separates out of a solution and requires a volume measurement in situ.

Usage Guide

For basic measurement of liquids in qualitative work a Class B flask is sufficient. For more accurate measurements Class A is appropriate. Class A flasks are calibrated to half the tolerance of Class B flasks and each has a unique serial number for traceability. A certificate of accuracy traceable to national standards can be provided if required. Class A flasks are used in analytical labs, quantitative labs and other controlled environments.
