Flask, Volumetric. Use these to prepare solutions
of known molarity or percentage. These flasks are marked as Class
A tolerance (Borosil are marked "B"). The 50 mL version is accurate
to +/- 0.05 mL at room temperature. For maximum precision you should calibrate your volumetric glassware with an analytical balance.
