Or a pipette could be used, either volumetric or disposable, and
eliminate trying to transfer small amounts from large bottles.  In
addition, elimination of 4 L bottles of concentrated acid in favor of 1
L bottles greatly reduces risk, both of spills and of the general load
on a lab.

In the case of the larger size bottles, one can pour the acid (or any
reagent) into a suitable size beaker then into the cylinder for
measuring.
