Corning PYREX Economical Reusable Volumetric Pipets were designed primarily for schools and laboratories where the Class A tolerances is not required. They are constructed with the same wall thickness and length, but have larger tip openings for faster delivery. It is primarily due to this faster delivery that accuracy tolerances are twice those specified for Class A volumetric ware.
